Cctv news Mid-Autumn Festival is a day with special meaning for Chinese, which means gathering, reunion and perfection. Seeing that the annual Mid-Autumn Festival is coming again, many people are looking forward to the Mid-Autumn Festival night, being able to get together with their families and eat a piece of moon cake handed by their families, leaving a fragrance in their mouths and feeling warm.

There is a "moon cake grandmother" Shen Yuee in Haining, Jiaxing, Zhejiang, who is 73 years old. The fresh meat moon cakes she makes are so delicious that it is hard to find a cake.

Every year around the Mid-Autumn Festival, she makes some moon cakes, not for sale, but for giving to others. Grandma Shen said that at first, she made meat moon cakes mainly to give them to the elderly in the community. Later, at the suggestion of her grandson, she began to send meat moon cakes to nursing homes and other places. Unconsciously, it has been four years since she persisted.

"Grandma Moon Cake" is short, kind-hearted and full of energy. Now, on average, she cooks thousands of moon cakes every day, including fresh meat, salt and pepper, and bean paste, which have many flavors. In order to make these moon cakes, Grandma Shen usually gets up at five or six o’clock in the morning and starts to prepare, mixing noodles, buying materials and mixing stuffing … until five or six o’clock in the evening. Later, in order to send it to the nursing home in time, Grandma Shen even needed to get up at 3 am. In addition to sending mooncakes to nursing homes and sanitation workers, Grandma Shen plans to send mooncakes to children’s welfare homes this year so that more people can taste her skills.

Grandma Shen’s good deeds have infected many people around her. Neighbor Zhao Hefen said: "Not only do you send cakes, but you also send zongzi on the Dragon Boat Festival and eight-treasure rice on the New Year. It is the same for everyone. It is really enthusiastic." Hearing others say that she is good, Shen Yuee is a little embarrassed: "Everyone says it’s delicious, so I’m strong enough."

Grandma Shen made moon cakes, and her family also supported her. Grandma Shen has a son and a daughter, both of whom are very promising. She is also keen on doing good deeds at ordinary times. When she knows that her mother wants to make moon cakes for those in need, they give great support both materially and spiritually.

Asked how long this mooncake will last, Grandma Shen said that as long as she has the conditions and ability, as long as she can do it, this mooncake will continue to be made and delivered, not to mention that there are so many people to help her and support her.

A small moon cake condenses Grandma Shen’s purity, truth, goodness and beauty. She sets an example for her children, neighbors and society, and conveys an unusual warm heart of an ordinary person. Another bright moon shines on Kyushu, and another Mid-Autumn Festival warms people’s hearts. Grandma Shen continues this enthusiasm and warmth. It is simple and precious, and it moistens things silently. Let’s say thank you to Grandma Shen!

　　From 23rd to 24th, the "Joint Sword-－2024A" exercise was conducted around Taitai Island in the Eastern Theater of the Chinese People’s Liberation Army.

　　Tan Zhu noticed that public opinion on the island was highly concerned about this large-scale military exercise without warning. Almost all the media immediately reported that China Times News published an editorial pointing out that Lai Qingde’s "Taiwan independence mania" undermined peace in the Taiwan Strait. Media commentator Wang Shangzhi thinks, "‘ Military exercise around the island ’ Appear faster than expected. " Lai Shibao, a representative of public opinion, said that the scale and scope of this "military exercise around the island" have been expanded compared with before, and Lai Qingde should be responsible for this. Analysts said that the PLA military exercise was the whole process of attacking Taiwan by force … …

　　In Tan Zhu’s view, this military exercise is a warning to Lai Qingde: If you dare to seek "independence" provocation, your sword will be drawn immediately!

unprecedented

Play "independence" mode

　　Tan Zhu’s comprehensive analysis of the scope and content of the exercise by military experts from both sides of the strait found that five remarkable features highlighted the unprecedented "independence" mode of the PLA.

　　The first is the exercise code.Lin Yingyou, an assistant professor at the Institute of International Affairs and Strategy of Tamkang University in Taiwan Province, analyzed that from last year’s "United Sword" to this year’s "United Sword -2024A", the "United Sword" exercise may be normalized in the future. Zheng Jian, a mainland military expert, told Tan Zhu that "A" means that if Lai Qingde persists in provocation, it will not be ruled out that there will be "B" and "C" & HELLIP; … The possibility.

　　The second is five encirclement circles.Taiwan Province Island is surrounded by the encirclement of Taipeng, Jinmen, Mazu, Dongyin and Wuqiuyu from three directions: north, south and east. Jie Zhong, a military expert on the island, noticed that this military exercise included "blockade operations" against several outer islands, and even "coastal island assault operations" against Dongyin Island, which was not practiced in the previous "military exercise around Taiwan". Zhang Chi, a mainland military expert, pointed out that the north deterred important political and military targets, the south besieged the important station of Taiwan Navy, and the east blocked the lifeline of Taiwan’s energy import, the escape line of "Taiwan independence" forces and the support line of external forces.

　　The third is the internal and external integration of the island chain.Jie Zhong said that this means that the PLA has the ability to send its powerful naval and air combat power to the tactical position in the western Pacific in eastern Taiwan Province, and cut off Taiwan Province’s external air and sea links. Zheng Jian told Tan Zhu that the PLA’s action was to announce to the "Taiwan independence" forces on the island and external interference forces that Taiwan Province is not a part of the "island chain" but a barrier to China’s national security. The PLA not only has the ability to crush "Taiwan independence", but also has the ability to refuse the so-called "rescue" from outside.

　　Fourth, approaching the "strategic rear" and "second wartime command post" of the Democratic Progressive Party authorities — — The Taiwan Air Force Hualien Base carried out military exercises.Lu Deyun, a military expert on the island, said that the exercise area off Hualien is extremely close to Taiwan Province Island, and the appearance of the liberation warship aircraft at such a close distance has put substantial pressure on the Lai Qingde authorities and the Taiwan military. There are also scholars on the island who believe that this also means that the so-called "combat power preservation" of the Taiwan military has no place at all.

　　Fifth, the three dimensions of "point, line and surface" have formed a threatening situation on Taiwan Province Island.Meng Xiangqing, a military expert on the mainland, pointed out that "point" means directly attacking the prime evil of "Taiwan independence" and pointing directly at the goal of "Taiwan independence". The "line" means that the key points of the exercise are connected into a powerful fire line that locks the island. "Face" means that the whole island of Taiwan Province is covered by a powerful fire net built by the PLA’s long-range fire, long-range guide and fighter planes. It can be said that this PLA exercise has a larger scale and a stronger flavor of actual combat.

Step by step

Military intimidation

　　Since the Democratic Progressive Party authorities came to power in 2016, this is another "military exercise around Taiwan" by the People’s Liberation Army to counter and punish the provocation of "independence". Some experts on the island pointed out that,Judging from several "military exercises around Taiwan", every time "Taiwan independence" provokes, the mainland’s military coercion in the Taiwan Strait will push further into the island.

　　In August 2022, Democratic Progressive Party authorities Goulian Pelosi made a surprise visit to Taiwan Province, and the PLA’s "military exercise around Taiwan" broke through the so-called "central line of the Straits" and "closed the door and beat the dog".At that time, Meng Xiangqing said, "‘ Strait midline ’ We never admit that "has become a hot topic in media reports on the island. According to the analysis of Qi Leyi, a military expert on the island, the military exercise reduced the depth of Taiwan Province’s "defense" to a minimum. Lin Yufang, a former public opinion representative on the island, said that the Taiwan military simply had no ability to break through the blockade.

　　In April 2023, Tsai Ing-Wen visited the United States, and the People’s Liberation Army conducted a "military exercise around Taiwan" and the aircraft carrier patrolled the east.At that time, public opinion on the island was highly focused on the appearance of the "Shandong Ship" aircraft carrier on the east coast of Taiwan Province. Experts on the island said that the "Shandong Ship" passed through the waters adjacent to Miyako Island and crossed the "first island chain", indicating that the "defensive rear" that Taiwan Province always thought no longer existed.

　　This exercise aimed at Lai Qingde’s provocation of seeking "independence" has achieved a new breakthrough.Meng Xiangqing said that Taiwan Island is a typical export-oriented economy, and 97% of its energy is imported. Once the island is blocked, its economy will collapse instantly, and the island may become a "dead island". The PLA focused on the new mode of blocking Taiwan Province Island. Meng Xiangqing emphasized that on the same day, Fujian Marine Police also organized a fleet of ships to carry out comprehensive law enforcement drills in the waters near Wuqiuyu Island and Dongyin Island. The released training diagram showed that the fleet of marine police ships was only 2.8 nautical miles away from Wuqiuyu Island and 3.1 nautical miles away from Dongyin Island, which completely broke through the so-called "restricted waters" designated by the Democratic Progressive Party authorities.

　　Liu Kuangyu, an associate researcher at Taiwan Province Institute of China Academy of Social Sciences, stressed in an exclusive interview with Master Tan that,The "six-way locking Taiwan" military exercise mode after the counter-Pelosi’s platform attack is still improving and strengthening step by step. Not only "circling the island" and "locking Taiwan" have become the new normal of the PLA’s military exercise against Taiwan, but also "anti-cutting sausage" has become the new normal.This fully shows that the more "Taiwan independence" provokes, the more the PLA tightens its blockade, speeds up its actual combat readiness, and strengthens anti-intervention and regional refusal.

　　Tan Zhu finally wants to say that the PLA’s military operations in the Taiwan Strait have gradually achieved the goal of "closing the door and beating dogs" and "locking turtles in a jar"", the aircraft carrier east patrol, internal resistance and external sealing, falsification of the "middle line", normal control, peacetime and wartime integration, joint warfare as the front. If "Taiwan independence" doesn’t pull back from the brink, it will be thunderous!

First, the third generation synchrotron radiation light source with the highest energy in the world

SPring-8, a large-scale synchrotron radiation facility in Japan, is located in Harima Science Garden City, Hyogo) in Hyogo Prefecture, the center of the Japanese archipelago. It is the third generation synchrotron radiation source with the highest energy in the world. Its English name is Spring-8, which means "8GeV Super Photon Ring", that is, the output power is 8 GeV.

In 1991, under the leadership of MEXT (Ministry of Education, Culture, Sports, Science and Technology), Jaeri (Japan Atomic Energy Research Institute) and Riken (the Institute of Physical and Chemical Research) of Japan began to jointly build SPring-8. The construction cost of the first phase is about 110 billion yen, and the land is donated by Hyogo Prefecture for free. With the joint support of the county government, the county university, various research institutes and commercial enterprises, the project was completed in 1997, and the facilities were opened, which were managed by JASRI (Japan Synchrotron Radiation Research Institute), including the operation, maintenance, transformation, user service and scientific research and development of light sources. JASRI is the only statutory management organization of SPring-8, which is private and non-profit, and employs more than 1,000 employees, 80% of whom are researchers and technicians. From October 1997 to 2010, SPring-8 has built 55 beam line stations.It has served more than 100,000 people in science, industry and business circles in Japan and the world.

Spring-8 in Japan, advanced photon source APS (Argone) in Argonne National Laboratory of the United States and European synchrotron radiation facility ESRF (Grenoble) in Grenoble, France are the three largest high-energy synchrotron radiation facilities in the world.

Third, structural exploration

The accelerator of SPring-8 mainly consists of four parts:　

* injector, Linac, 1GeV；;　

* Booster, 8 GeV;

* large Storage Ring, storage ring, 8GeV, used for high brightness X-ray;　

* Small storage ring, NewSUBARU, 1.5GeV, used for medium short pulse soft X-ray.

　　1. Injector (Linac)　

The linear accelerator section is equipped with 26 3-meter-long accelerating units to accelerate the electron beam energy to 1GeV. The red part in the picture below is a quadrupole magnet used to focus the electron beam.　　

Linear accelerator unit 1　

The electron beam is generated by a thermionic gun impregnated with barium and tungsten. The ion gun is located on the high-voltage board with a voltage of about 180KV. The pulse duration is 1ns or 40ns. The selected beam is focused on a buncher and accelerated to 1GeV energy with 25 accelerating cavities. Electron beam energy dispersion is reduced by energy compressor system (ECS). Then, the linear accelerator as the injector transports the electron beam to the intensifier or the NewSUBARU small storage ring.　

Some parameters of linear accelerator:

2. Booster Synchrotron

Annular, with a circumference of 396 meters. The 1GeV electron beam output from the linear accelerator will be accelerated to 8GeV in the intensifier. The blue image below shows the deflection magnet, which is used to generate synchronous radiation light; The yellow part is a six-stage magnet for stabilizing the electron beam.

Intensifier tunnel intensifier branch point (left) electron beam transport line SSBT (right)　

In FODO, the magnetic focusing structure of the intensifier, bending magnets and quadrupole magnets are alternately arranged, and the repetition frequency of injection, acceleration and output is set to 1Hz, and the harmonic number is 672. If a single beam is injected into the storage ring, an RF elimination system is installed to eliminate other electron beams adjacent to the main beam. The special timing system injects different beams according to the types of light required by each outlet station of the storage ring.　

Some parameters of the enhancer:

3. The large Storage Ring (storage ring)

The electron beam is injected into the storage ring from the transport line SSBT (left).

Huge ring with a circumference of 1436 meters. Its conventional unit consists of 2 deflection magnets, 10 four-stage magnets and 7 six-stage magnets, and its length is about 30 meters. The linear joints are located between conventional units, and are used to install plug-ins, RF accelerating cavities, beam injection systems, beam diagnosis systems, etc., with a total of 44 linear joints.　

Some parameters of large storage ring:

The large storage ring can store 8GeV electron beams for a long time, more than 100 hours. The energy consumed by synchrotron radiation is replenished by accelerating equipment installed in four radio stations around the storage ring. The constant current (top-up) injection mode effectively ensures the constant beam current intensity in the storage ring.　

Link: The 86th academic seminar of the Oriental Science and Technology Forum was held on December 7-8, 2006, with the topic of "beam orbit stability of the third generation synchrotron radiation light source".　

Dr Kouichi Soutome from Japan synchrotron radiation research institute (JASRI) gave a special report on "constant current injection and beam orbit stability of SPring-8". He first emphasized the necessity of providing users with a stable X-ray beam for precision experiments. In order to stabilize the beam position, it is necessary to restrain the beam trajectory change. He pointed out that the top-up injection mode with constant beam intensity in the storage ring can effectively ensure the stability of the synchrotron radiation light intensity. For this reason, SPring-8 has made great efforts to study the sources of various factors that cause orbit change, such as the change of magnet power supply and the vibration of vacuum chamber caused by cooling water.

SPring-8 also improves the beam trajectory correction system and the corresponding measurement system. For top-up implantation, SPing-8 adopts many measures, such as reducing the vibration of stored electron beam caused by implantation, reducing the loss of implanted electron beam, and maintaining long-term high-purity single beam implantation. Finally, he reported the stability of SPring-8 in beam orbit and the performance of top-up injection operation mode. The total current stability in SPring-8 storage ring is controlled within 0.1%, and the current intensity inconsistency of each beam is also controlled within 10%.　

4. NewSUBARU

　　NewSUBARU storage ring　

NewSUBARU, a small storage ring with 1.5GeV, is mainly used to study the application of soft X-ray in industrial field. Built in 1998, Lasti (Laboratory of Advanced Science and Technology for Industry) of Hyogo University is responsible for its operation.　

The circumference of the small storage ring is about 119 meters, and it consists of two 14-meter and four 2.6-meter straight-line sections. In the long straight section, an 11-meter-long undulator and an optical klystron free electron laser device are installed. The electron beam of 1GeV in the linear accelerator can be directly injected into the storage ring.

　　11-meter-long undulator

Some parameters of small storage ring:

Four, beam line and experimental station

SPring-8 has 22 beam lines led by deflection magnets, and up to 24 can be built. There are 26 beam lines led out by the insert, up to 34 can be built, and the length of the straight line section is 4.5 meters; There is one beam line led by the long insert, and at most four beams can be built, and the length of the long straight line section is 25m. These beam lines are generally designed within 80 meters, but 9 can extend to 300 meters and 3 can extend to 1 kilometer.　

1. Layout and classification　

The front-end assembly of the beam line is designed to withstand radiation power, reduce the thermal load of the first optical element in contact, and protect the vacuum of the storage ring in case of beam line failure.

V. Major scientific research achievements

1. Uncover the secret of the mysterious structure and movement mode of water molecules.

Water is a familiar substance, and the structure of water molecule H2O is well known. But perhaps people haven’t thought deeply: where does ice store huge cooling energy? Why is the density of water the highest at 4oC? But above or below 4oC, the water density decreases? Why is the density of solid ice less than liquid water?

Japanese scientists analyzed the structure of water and ice in SPring-8, and some new discoveries solved the long-debated problem about the nature of water. They successfully conducted Compton scattering experiment by using high-energy inelastic scattering beam line BL08W, directly observed the structure and function of ice at high resolution, and verified the accuracy of molecular dynamics simulation. This basic research result can help to develop thermal storage materials and analyze the thermal storage of new materials in the future. The paper was published in the top American science journals.

In fact, as early as 2008, scientists from RIKEN Institute of Physics and Chemistry in Japan proposed two water states with different hydrogen bonding modes by using BL17SU beam line and soft X-ray spectrum of SPring-8, as well as small angle scattering and Raman scattering.

2. Develop general-purpose plastic materials as strong as iron.

Plastic products such as plastic bags and plastic buckets have become widely used and indispensable items in our daily life because they are light, waterproof and cheap. But at the same time, it also has some disadvantages: low tensile strength, easy deformation and not high temperature resistance. They are synthesized from polymers such as polyethylene and polypropylene, and their structures at the molecular level are composed of long chains of carbon atoms. This "string" structure of polymer makes plastic products as soft as biomaterials. However, scientists have found that the tensile strength of materials will increase with the increase of polymer chain length; When carbon chains have tensile strength similar to covalent bonds of carbon atoms in diamonds, general plastics will harden, but they will not have diamond-like strength.

Distinguished professor Hikosaka of The Graduate School of Integrated Arts and Sciences (Hiroshima University) focuses on the study of polymer long chains and their structural and characteristic changes. He examined the blending phase structure of polyethylene long chain and its influence on properties by X-ray diffraction and other methods. The growth mechanism, sliding and diffusion effect mechanism of ideal polymer crystals are formulated. In 1987, the "sliding diffusion theory of polymer crystallization" was put forward.

The research team led by Professor Iwasaka and his doctoral student Kiyoka Okada, who used BL40B2 beam line in 2003-2007, observed the process of nuclear nucleation. ) From 2007 to 2010, using the X-ray scattering device of SPring-8, a new polypropylene-based plastic with strong tensile force and super heat resistance was successfully developed for the first time: NOCs(nano-oriented crystals).

The reason why ordinary plastics have poor tensile strength is because of low crystallinity. High-quality plastics are those with crystallinity of about 50%. In other words, the higher the crystallinity, the stronger the intermolecular interaction, and the stronger the tensile strength and heat resistance. When polymer molecules are regularly arranged, crystals form. Therefore, in order to improve the crystallinity, it is necessary to arrange the polymer molecules regularly as much as possible.

Professor Masamichi Hikosaka, Dr. Kiyoka Okada, holds a new type of polypropylene.

The research team led by Professor Iwasaka found a method to make polymers regularly arranged when plastics are in molten state, and proved that the crystallinity of the method is 92%. Because the structure of NOCsS looks like a real armor, it is composed of small pieces of iron plates, so the model is called "real armor" model. The tensile strength of the new polypropylene is about seven times higher than that of the ordinary plastic material, the heat-resistant temperature reaches 170°C or higher than 176°C, the light transmittance is 99%, and it is recyclable and cheap, because only one process is needed in the traditional polypropylene production process.

This wonderful new plastic material is most likely to be used in the transformation of steel body in traditional automobile industry. Although the thickness of the body will be doubled, its weight is only a quarter of that of steel.

3. Analyze the change of dynamic structure of calcium pump.

A variety of ions participate in the biological activity of organisms. Calcium 2+ ion promotes muscle movement and is one of the most important ions in organisms. It is stored in the endoplasmic reticulum of myofibrils. When calcium ions are released into muscle cells, muscles contract. At the same time, calcium ions need to return to the endoplasmic reticulum to relax the muscles. A membrane protein called calcium pump is responsible for pumping back calcium 2+ ions.

Pumping back calcium ions involves two processes: obtaining and releasing, and the structure of calcium pump changes accordingly. Chikashi Toyoshima (Institute of Molecular and Cellular Biosciences of the University of Tokyo) first discovered this structural change and analyzed the calcium pump structure in nine states.

His research results were published in the British journal Nature in 2000, 2002 and 2004. In view of this series of outstanding achievements, Professor Toyoda was awarded the Asahi Prize in 2009.

4. Discovery of new magnetic materials on meteorites

Every year, thousands of tons of meteorites fall to the earth. Although their surfaces are burnt black, their internal metal and mineral components remain unchanged, so they are called "fossils" in space. It provides powerful evidence for human beings to understand the mysteries of the solar system.

Masato Kotsugi, JASRI) of Japan Synchrotron Radiation Research Institute used the Photoelectron Emission Microscope (PEEM) on BL25SU beam line of SPring-8 to analyze the structure of iron meteorites. Iron meteorite is composed of α phase rich in iron and γ phase rich in nickel. Dr. Xiao Shan confirmed that there is a nano-scale mineral layer at the interface between iron and nickel, which is called Tetrataenite. However, it does not exist on the earth and will become an excellent new magnetic material. Dr. Xiao Shan further analyzed the characteristics of Tetrataenite, which is composed of 50% iron and 50% nickel, and the iron and nickel atoms are alternately arranged, which is a regular periodic crystal structure. It produces a kind of hard magnetism, that is, the magnetization direction will not change easily. Famous hard magnetic materials include permanent magnets and materials used in engines of hybrid vehicles.

Another important discovery of Dr. Xiao Shan: Tetrataenite will be a potential substitute in hard disk manufacturing. Platinum is an indispensable material for the next generation hard disk, but it is a rare metal, and its price is rising. At present, the demand for platinum has exceeded its production capacity. About 2 tons of platinum is used in global hard disk production every year. If Tetrataenite synthesized by iron and nickel can be used as hard disk material, the consumption of platinum will be greatly reduced, thus promoting resource conservation and low-cost production of hard disks.

Chiharu Mitsumata (Toho Kyu University) of Tohoku University in Japan is carrying out basic research on the synthesis of Tetrataenite.

As a result, Dr. Koyama and Professor Sanyan won the second place in Dubose-Crouse Award (international metallic graphic contest) in 2010.

　5. Successfully developed all-solid-state safety battery by nanotechnology.

Professor Hiroshi Kitagawa (Kyoto University) of Kyoto University and Dr Rie Makiura (Kyushu University) of Kyushu University have studied nano-scale silver iodide (AgI) particles. They proved for the first time in the world that it is possible to realize stable solid electrolyte at room temperature. This research achievement is highly valued because of its great development potential. The paper was published in the British scientific journal Nature Materials in May 2009.

6. the three-dimensional structures of Rab27B and Slac2-a are analyzed.

In 2004, Dr. Mitsunori Fukuda (Tohoku University) of the Graduate School of Life Sciences of Northeastern University clarified the transmission mechanism of melanin in melanocytes at the molecular level. In 2008, in cooperation with Shigeyuki Yokoyama of RIKEN Institute of Physical Chemistry, he successfully analyzed the three-dimensional structures of Rab27B and Slac2-a in BL41XU Experimental Station of Structural Biology on SPring-8. Their structural data will greatly promote the research and development of new skin whitening products and drugs to prevent white hair.

7. The new chewing gum Pos-Ca can effectively prevent tooth decay.

Dr. Tomoko Tanaka (the Health Science Laboratory of Ezaki Glico Co., Ltd.) found that calcium phosphate oligosaccharide supported the remineralization of teeth, which promoted the appearance of new chewing gum with calcium phosphate oligosaccharide (Pos-Ca).

8. Research and development of new drugs against influenza virus

Influenza virus consists of eight RNA genes, and there are two types of spike proteins on the surface of virus particles: hemagglutinin (HA) and neuraminidase (NA). Because of its simple structure, the virus cannot replicate itself. However, they can be skillfully replicated by using the replication system of human cells after invading human host cells.

HA, like a key, can invade the human body after combining with glycoprotein on the cell surface. NA plays an important role in the separation and release of progeny virus from cells, and is an enzyme that helps the virus infect other bacteria. The amino acids that make up the above two proteins are prone to mutation. So far, scientists have discovered 16 kinds of HA and 9 kinds of NA proteins. These protein are arbitrarily combined into various types of influenza viruses (H1N1–H16N9). For example, influenza A H1N1, which was prevalent in 2009, and H5N1 virus, avian influenza, which became prevalent in 1997.

Influenza virus encodes 10 kinds of proteins, among which RNA polymerase is very important in virus gene replication. It includes three subunits: PA, PB1 and PB2. When one of them is lacking, RNA polymerase loses its enzyme function and the virus cannot replicate. Therefore, if we can determine the three-dimensional structure of these three subunits, we can block the function of RNA polymerase.

In July 2008, Dr. Sam-Sam (Graduate School of Nanobioscience, yokohama city university) successfully analyzed the combined structure of PA and PB1, and analyzed the enzyme structure related to virus replication, which will accelerate the research and development of new antiviral drugs. It is not far away to realize the wish that people don’t have to worry about the flu in winter.

9. Reveal the secret of solar system formation by analyzing comet dust.

The American Stardust Project, 1999-2007) collected scattered dust samples of comet Wilder II (81P/Wild) and brought them back to Earth. It is expected that by analyzing these samples, information about the origin of comets and the entire solar system 4.6 billion years ago can be obtained.

Dr. Tomoki Nakamura (Kyushu University) of Kyushu University has conducted in-depth research on comet dust. He used the X-ray diffraction experimental device of BL37XU on SPring-8 and the synchrotron radiation facility of KEK to analyze and determine the crystal types and abundance ratio of dust. After that, Professor Akira Tsuchiyama (Osaka University) used the CT scan of BL47XU to visualize the internal structure of comet dust.

Dr. Nakamura found that "meteorite chondrules" originated from comet dust outside the solar system, so they can no longer be explained by the traditional model of solar system formation. "Meteorite chondrules" are the main components of ancient meteorites, rich in magnesium, silicon and a small amount of iron. The doctor believes that the migration of "globules" occurred in the primitive solar system composed of dust disks; However, he said that the analysis accuracy of at least 20 samples will be improved to obtain statistically significant conclusions. He will also continue to carry out comet meteorite dating and determine the migration time. It is expected that a new solar system formation model will be established soon.

10. Nanotechnology promotes the innovation of "new materials"

The shape characteristics of fullerenes discovered in 1985-containing 60 carbon atoms, like a football-have aroused widespread concern in the scientific community. In 1991, columnar carbon nanotubes were discovered. In January, 2008, Associate Professor Kitura & Hisa Nori Shinohara (Nagoya University) of Nagoya University successfully synthesized a nano-scale metal wire.

Carbon allotropes: diamonds and graphite, fullerenes and carbon nanotubes.

Pure gold is prone to oxidation reaction, but a very thin nanowire can exist stably in the air because nano-scale materials have a unique stable structure. In order to observe the internal structure of nanotubes, Associate Professor Bei Puliang conducted solid soft X-ray spectroscopy experiments at BL25SU experimental station in Spring–8. He observed that the absorption of Er by X-rays was unique, thus confirming that ErCl3 line was formed in carbon nanotubes.

Carbon nanotubes in fullerenes look like pods.

ErCL3 structural model (Er atoms in red and CL atoms in green)

Professor Tian Zhuo (University of Tokyo/RIKEN) of Tokyo University and Institute of Physical Chemistry is regarded as the most imaginative and productive polymer chemist in the world. In recent years, he took SPring-8 as an important research tool, and first successfully determined the structure of a new type of conductive graphite nanotubes. Then, he showed with solid evidence that the hydrophilicity and hydrophobicity of graphite molecules were closely connected in hydrophobic groups, forming tubular spiral molecular pairs. In addition, he also successfully designed a liquid crystal phase with short intermolecular programs. Both research results were published in the Journal American Chemical Society in 2008. In 2009, the design of "bicontinuous cubic liquid crystal materials in discoid molecules" was published on the cover of the magazine of American Chemical Society, and he also won the Polymer Chemistry Award of American Chemical Society.

11. Develop earthquake observation technology.

With the joint efforts of Tokyo Institute of Technology, Japan Agency of Marine-Earth Science and Technology and Japan Synchrotron Radiation Research Center (JASRI), it is found that the deepest part of the earth’s core is made of iron with hexagonal close-packed structure. The state of metallic iron under ultra-high pressure and ultra-high temperature conditions is similar to the state of the earth’s core simulated by ultra-high pressure and ultra-high temperature. Scientists used SPring-8 high-brightness X-ray to observe the changes of single crystal structure of metallic iron, and found for the first time that the hexagonal close-packed structure was stable under extreme conditions of high temperature and high pressure. The analysis of the crystal structure is helpful to the analysis of earthquake observation and greatly strengthens people’s understanding of the formation and development of the core. This achievement was published in the American journal Science on October 15th, 2010.

12. Analyze the gel mechanism of self-assembly from the molecular level.

Recently, a joint research group of The University of Kitakyushu and JARSI announced that the molecular structure of the solvent in the gel state was analyzed on the BL03XU Advanced Soft Materials and BL40B2 Structural Biology II Experimental Station by using SPring-8 high-brightness synchrotron radiation. The research results benefit from organogelator (low molecular weight compound). As long as 1% solvent is added to it, the whole solvent will gel, which will greatly help to prevent environmental pollution caused by offshore oil spill. The paper was published online in the October 2010 issue of Polymer Journal.

Sixth, look forward to the future

The resolution of traditional optical microscope is limited by the wavelength of light, while the wavelength of X-ray is 10,000 times shorter than that of visible light, and the resolution reaches the atomic level, which means that the three-dimensional structure of a single atom in matter can be observed. X-ray is widely used in medical treatment, life science and material science. However, the light generated by X-ray light sources (including synchrotron radiation) is not uniform and the wave fields are inconsistent. Laser can produce uniform light by using a pair of mirrors. This urges scientists to make every effort to explore a new technology to realize a mirrorless laser, that is, XFEL: X-ray Free Electron Laser (XFEL). XFEL is an X-ray that combines the characteristics of free-electron laser. It is called the most promising new light source in the future with the most scientific exploration and discovery value. It is also called "dream light source" and "new dawn of the scientific era". It has the dual characteristics of laser and radiation light, and can work in the whole X-ray band. It is much better than the third generation synchrotron radiation light source in brightness, coherence and time structure, and is internationally recognized as one of the feasible technical routes of the "fourth generation light source".

The United States, Europe and Japan have successively developed XFEL, and raised it to the height of national strategy to deploy and implement it. LCLS(Linac Coherent Light Source, Stanford Linear Accelerator Center, USA), the first X-ray free electron laser device in the world, came out in 2009. The European Free Electron Laser Facility (European XFEL) is jointly participated by DESY of Germany and 11 other European countries. The core project is a 3.4-kilometer underground tunnel, which was officially started on July 1, 2010. It is expected to be completed in 2014 and the first scientific experiment will be conducted in 2015.

SPring-8 has already started the prefabrication and research of XFEL, and the accelerator prototype has successfully produced the first laser beam. In 2006, the XFEL project started. At present, the 700-meter-long 8GeV X-ray free electron laser device is under final construction and is expected to be put into operation in fiscal year 2011. exist

2.XFEL facilities

SPring-8′ s X-rays can produce light 10 billion times brighter than the sun, while XFEL produces light 1 billion times brighter than SPring-8, and the pulse is 1000 times shorter than the existing X-ray source. The higher brightness light source enables scientists to observe the three-dimensional structure of atoms and their ultra-fast motion more realistically.

Design parameters:

Electron beam energy: 8 GeV

Electron beam diameter: 40 um

X-ray wavelength: > 0.06 nm

X-ray peak power: 5 GW

X-ray pulse length: < 100fsec

X-ray peak brightness: 1033 photons/s/mm2/mrad2/0.1% b.w. 。

The original quality of electron beam determines the quality of free electron laser. Scientists have specially designed an ultra-high voltage thermal electron gun, which uses a single-crystal cerium-hexabromoboride cathode (CEB 6) to emit a fine, highly collimated and stable electron beam. Then, it is transported into the electron beam compression system, and the peak current will be strengthened to several thousand amperes.

The electron beam energy is rapidly increased to 8GeV by a C-band linear accelerator, and then transported into a vacuum undulator to generate intense XFEL radiation.

C-band linear accelerator was developed by SPring-8 and KEK. C-band acceleration gradient (35MeV/m) greatly shortens the length of the accelerator. The total length was originally an accelerator structure with a precision of 1282mia and micron, and it was finally installed in a tunnel with a length of 400m.

3. Create new technologies

Coherent X-ray imaging technology: Microscopic images of various materials at atomic level can be obtained.

Imaging process: X-ray laser → sample → coherent scattering mode → phase recovery → clear structure image.

XFEL’s ultrashort pulse can detect the ultrafast motion of matter in femtosecond.

Protein Structure Analysis: The analysis of new materials will surely lead to the birth of new functional products in biology and medicine.

Living cell biology: Real-time data acquisition will open a new way for the study of living cells.

Nanotechnology: Ultra-short wave XFEL will help to create new functional materials.

With XFEL, scientists can observe extreme phenomena in astronomy, plasma science and basic physics.

The Institute for Molecular Science, Niigata University, Nagoya University and JASRI/RIKEN of the National Research Institute of Japan jointly studied the intense ultraviolet free electron laser irradiated to argon atoms, and successfully analyzed the specific process of multi-electron emission.

In order to accurately measure the fluctuation in free electron laser, scientists analyzed all the electronic energy of argon atom irradiated by laser pulse at the speed of 20 pulses per second. They found that the absorption of electrons and multiphotons only occurs when the light intensity is very high, and clarified the importance of resonance state in multiphoton absorption. The research results show that the research of nano-science, nano-technology and material preparation can be promoted by using X-free electron laser on the basis of selecting appropriate laser wavelength and corresponding resonance conditions. The paper was published in american physical society’s scientific journal Physical Review Express on September 24th, 2010.

The information comes from http://www.spring8.or.jp/en/.

Vanke’s largest shareholder has changed.

On the evening of June 9th, China Evergrande (0333.HK) announced that it had transferred 1553210974 shares of Vanke A(000002.SZ) to Shenzhen Metro Group for 29.2 billion yuan, with a shareholding ratio of 14.07%.

Subsequently, Vanke Enterprise Co., Ltd. (000002.SZ) also announced that Shenzhen Metro Group Co., Ltd. will hold 3242810791 shares of Vanke A shares, accounting for 29.38% of the company’s total share capital, becoming the largest shareholder of Vanke.

According to the information disclosed by both parties, the consideration for the sale of Vanke A shares by Evergrande this time is 18.80 yuan/share. According to the previously disclosed data, the cost of holding Vanke A by Evergrande is 23.35 yuan/share. Evergrande’s loss from the sale of Vanke A shares was 7.07 billion yuan. Evergrande plans to use the proceeds from the sale mainly to repay the debts of the Group.

At this year’s performance conference of Evergrande, a reporter asked if he would be unwilling to accept Vanke’s investment loss. Xu Jiayin’s answer is, "How can you say that you are unwilling to do something? Everything you do is a pleasant thing."

For Shenzhen Metro, this is the second time this year that it has received the equity of Vanke.

On January 13th this year, Shenzhen Railway has bought 15.31% shares of Vanke A from China Resources. Together with the shares of Vanke bought from Evergrande this time, it has become the largest shareholder of Vanke with a shareholding ratio of 29.38%, while Baoneng has retired to the second largest shareholder of Vanke with a shareholding ratio of 25.4%, and Anbang is the third largest shareholder with a shareholding ratio of 6.73%.

At this point, Evergrande has completely withdrawn from the battle of "Bao Wan".

Since Evergrande first disclosed the purchase of Vanke A on August 4, 2016, Evergrande spent 36.273 billion yuan on the acquisition of Vanke A..

Before the sale of Vanke’s shares, Evergrande irrevocably entrusted the voting rights, proposal rights and the right to attend the shareholders’ meeting of Vanke to Shenzhen Railway on March 16, and Shenzhen Railway decided to exercise it at its own discretion. At that time, the agreed period was one year.

It is worth mentioning that after Evergrande made this decision, it also indicates that Evergrande will give up the nomination right of Vanke’s director candidates.

At that time, Shenzhen Railway once said that as an important shareholder and strategic investor of Vanke, Shenzhen Metro Group is optimistic about the future development prospects of Vanke and does not rule out continuing to increase its shareholding in Vanke in the future.

As the largest shareholder of Vanke, there is only about one month left before the lifting of the ban on Vanke shares held by Baoneng Department. According to the provisions of the Securities Law and the Measures for the Administration of the Acquisition of Listed Companies, in the acquisition of listed companies, the purchaser’s shareholding shall not be transferred within 12 months after the completion of the acquisition. According to the regulations of the CSRC, investors who acquire shares of listed companies and become the largest shareholder, but the shareholding ratio is less than 30%, should also abide by this regulation.

According to the fact that Baoneng was the largest shareholder of Vanke before, every time it increased its holdings, the shares held by its name and its concerted parties needed to be correspondingly extended and locked for 12 months. Up to now, the last time Baoneng purchased Vanke A was on July 6, 2016. Based on this calculation, Baoneng’s shares in Vanke A can be sold after July 6.

At the close, China Evergrande reported HK$ 16.64 per share, down by 0.12%. Vanke’s announcement on the same day showed that the company will resume trading on June 12.

According to the previous arrangement, Vanke will hold the 2016 annual general meeting of shareholders on June 30, 2017. However, the issue of "general election of the board of directors", which is generally concerned by the market, is still not mentioned in the agenda of this shareholders’ meeting. As of the end of June, Vanke’s board of directors will serve for three months.

In this regard, Vanke told The Paper that there is still no timetable for the re-election of the board of directors. According to Vanke’s statement when answering investors’ questions in Shenzhen Stock Exchange on May 16th, the change plan is being actively brewed, and once it is mature, it will start the change immediately.

　　Passing Yang Jie, the director of The Journey to the West, made him become attached to Tang Priest, and successfully shaped the role of Tang Priest in The Journey to the West, becoming the last Tang Priest to "get the true scriptures";

　　His marriage with Ms. Chen Lihua, who is ten years older than him, has caused a lot of controversy, and he laughed it off.

　　After the marriage, he quietly walked off the stage, quit the screen, and then walked out of the public eye.

　　● Yesterday reappeared.

　　On December 23rd, 1952, Zhongrui Chi was born into a family of five generations of Peking Opera in Beijing. He was deeply influenced by the art of Peking Opera since childhood. However, Zhongrui Chi failed to take the road of Peking Opera in the end, for one thing, he was 1.80 meters tall, and for another, he caught up with the Cultural Revolution in China.

　　Although he didn’t enter Beijing Opera, the artistic edification he received since he was a child can’t be lost. Zhongrui Chi took a tortuous artistic path: first he worked as a farmer in Heilongjiang Construction Corps, and then he worked as a literary and art soldier in Yunnan. After he retired, he was admitted to China Broadcasting Art Troupe. Two years later, he was sent to Shanghai Theatre Academy to go to college and became the first batch of college students after the Cultural Revolution.

　　After graduation, Zhongrui Chi came to China TV production center and became a professional actor. He has shot a large number of film and television works, playing Du Mingguang in Golden Late Autumn. The second son Huan in "Love in the Pen"; Sun Shuikang, the leader of aquatic products in This is not a misunderstanding; Characters such as Sai Shang Xiao in Harbin at Night.

　　One day in 1984, Zhongrui Chi finished filming Harbin at Night and went back to the troupe to get his salary. In the dark corridor, he almost ran into an oncoming stranger, Yang Jie, the director of The Journey to the West.

　　At that time, The Journey to the West had just filmed half of it. Xu Shaohua, the actor of Tang Priest, had to leave the crew for some reason. Without the "master", the whole crew was in a state of downtime, and director Yang Jiezheng was so anxious about it that she met Zhongrui Chi.

　　"I have to say that this is the Buddha’s edge. When I passed by in the corridor, Yang Jie decided that I was the best candidate for Tang Priest. A week after we met, I put on my cassock and rode on Bai Longma. "

　　In 1988, The Journey to the West premiered in China, and the Tang Priest played by Zhongrui Chi was unanimously recognized by the audience. The four men became the most popular stars for a time, and attracted much attention wherever they went. However, at this moment, Zhongrui Chi chose to leave. He married Ms. Chen Lihua, the richest man in China, who was ten years older than him, and retired from the entertainment industry and started a new life.

　　Our reporter takes you to visit the new life in Zhongrui Chi.

　　They had a glorious history; They may have spent your youth with you; They used to be idols of a generation … Time flies and times have changed. Now they have bid farewell to their glory and started a new life. Show you their second life by comparing them. In this issue, the character-Zhongrui Chi is recorded.

　　"Late Chief" in Luxury Palace [nowadays]

　　At 9: 00 a.m. in a spring March, we arrived at the gate of China Red Sandalwood Museum on the northwest side of Gaobeidian Bridge in Beijing’s East Fourth Ring Road. Compared with the busy and congested streets in the morning rush hour, it was particularly spacious and deserted.

　　At the gate, a big boy wearing a security uniform just pushed out the wooden box for collecting tickets. Under his guidance, we bypassed the museum in front and came to the back. We walked past a stone bridge, and there was a building with more than ten floors. The exquisite decoration of the building made people think of the word "magnificent". Upstairs, in the middle of the building, the three golden characters "Lihua Pavilion" shine in the sun.

　　Walking into the interior of Lihua Pavilion, you will immediately feel the solemnity and luxury inside, just like walking into an ancient palace: there is a wide rosewood screen facing you, a huge and beautiful crystal chandelier overhead, all doors, windows and partitions are made of wood, with couplets and carved beams and painted buildings, and two elevators are hidden behind the antique wooden door frame, which makes people have to sigh the perfect combination of classical and modern.

　　This is a modern comprehensive building with a classical appearance, with office area, hotel, gym, swimming pool, KTV and so on.

　　We were taken into a reception room on the second floor. There are three floors in the room, which are still wooden doors, wooden windows and wooden floors. The outermost room is a rosewood screen, a plush chair and a mahogany long table, the second room is a circle of sofas and coffee tables, and the innermost room is a rosewood collapse. No sooner had we settled down in the plush chair than someone came in and poured tea.

　　After sitting for a moment, with the sound of footsteps coming from the corridor and the greeting of the staff, Zhongrui Chi came in. He was in a good mental state, flushed and with a gentle smile on his face. It is still the appearance of the Tang Priest in The Journey to the West in the past, and it is still a loud and magnetic voice. The opening remarks are: "As soon as you see this rosewood museum, you will understand what I have done since I left the audience for more than ten years, at a glance."

　　Why did Zhongrui Chi, who successfully shaped the role of Tang Priest in The Journey to the West, put aside his good performing career and open the rosewood museum instead? This has to start with his marriage.

　　In a resort hotel in Suzhou, Ms. Zhang and her family booked a 2-night stay, as well as a 2-day vegetarian meal and Chinese massage. "Our family has &lsquo; Yangkang &rsquo; After a while, the relevant policies have been relaxed, and our family has not traveled for a long time, so we hope to go out for fun, but unlike before, &lsquo; Yangkang &rsquo; After that, we paid more attention to healing tourism, instead of arranging too full a trip, mainly to relax ourselves and even add some rehabilitation projects. " Ms. Zhang said.

　　Ms. Zhang’s travel choices and ideas are typical representatives of many tourists this year. CBN recently publicly conducted a questionnaire survey on "Consumer Recovery, Will You Buy in buy buy?" After collecting more than 1,200 valid questionnaires, it was found that it was asked "Which fields of goods or services would you consume?" At that time, tourism ranked first, reaching 91.24%. In other words, tourism that can satisfy people’s spiritual pleasure consumption is what most people will choose in the consumer market this year, and many tourists’ willingness to travel this year is obviously strengthened compared with previous years.

　　After recent interviews and investigations, the First Financial Reporter learned that this year, with the recovery of outbound travel and the warming of inter-provincial travel, tourism will inevitably usher in recovery and business opportunities. After experiencing the epidemic, more tourists began to favor healing tours and some extended cultural tours with experience. Of course, how to restart the outbound travel business, do a good job in the derivative projects of Dawen Travel and attract tourism professionals are also challenges that the industry needs to face.

　　90% of the respondents want to travel, and nearly 60% of the tourists have a single budget of more than 10,000 yuan.

　　In the three years since the epidemic, outbound travel has been suspended, domestic travel has been repeatedly blown, and repeated epidemics in various places have also made scenic spots open and closed. Local consumption has become the main mode of tourism in the past three years, which has given birth to some in-depth local tourism products.

　　This year, with the relaxation of relevant policies, people’s willingness to travel, which has been suppressed for many years, seems to have a "small blowout". According to the questionnaire survey of CBN’s Consumer Recovery, Will You Buy in buy buy, 91.24% of the respondents chose to have a travel plan this year. When asked whether this year’s willingness to travel has increased compared with previous years, 85.85% of the respondents said that this year’s willingness to travel has increased or at least remained the same.

　　The above questionnaire survey also shows that 60.2% of the respondents have plans for domestic travel this year, and 32.37% of the respondents plan to go both for domestic travel and outbound travel this year.

　　In terms of tourism consumption expenditure, 57.39% of the respondents have a budget of 10,000 ~ 20,000 yuan per capita for single tourism consumption this year, and 32.6% of the respondents have a budget of 5,000 ~ 10,000 yuan for single tourism consumption, accounting for 5.63% of the respondents with 1000 yuan ~ 5,000 yuan.

　　"In 2019, the tourism industry reached a relative peak. The tourism market in the past few years should have been very vigorous. However, when it encountered an epidemic, both domestic and outbound travel were hit. However, after the epidemic, people have strengthened their willingness to travel, and some spiritual pleasures have been favored by people. You see, in the consumption of Women’s Day just past, &lsquo; Yueji &rsquo; It’s a key word. Women are very particular about their inner experience when they travel. Therefore, we will see that in the process of consumption recovery this year, more subdivided products with spiritual pleasure will be released, and more themed tourist routes and accommodation products will be developed. " Cheng Chaogong, chief researcher of Tongcheng Research Institute, told the First Financial Reporter.

　　Inter-provincial tourism is heating up, and the healing market has great potential.

　　According to the tourism market data of Spring Festival, Women’s Day and other nodes this year, domestic tourism is the first to recover, and the results of the questionnaire survey of "Consumption Recovery, Will You Buy in buy buy" of CBN also show that 60.2% of the respondents have plans for domestic tourism this year.

　　"Last year’s camping was in the market &lsquo; Kill &rsquo; Out of a horse &lsquo; Dark horse &rsquo; In fact, it is also a market cultivated because everyone can only focus on local consumption. Among them, the consumption of camping, RV and related supplies increased significantly in 2022. " Yang Songbai, general manager of RV Life Home, told the First Financial Reporter.

　　According to the data of companies such as Ctrip, Tongcheng, Mama Donkey, Flying Pig, Qunar, Tuniu, Mahoneycomb and Spring and Autumn Tourism, last year, in low-risk areas, the "two-hour holiday circle" became the mainstream. Last year, the local tour orders during holidays such as "May Day" accounted for more than 80%, and most of them were non-group tourists, while camping became a "dark horse". The surrounding camping market continued to heat up during the "May Day" last year, and the popularity of "camping" related travel search increased by 117% from the previous month. At that time, the number of camping orders for flying pigs increased by over 350% month-on-month, and Hangzhou, Chengdu, Guangzhou, Shenzhen, Wuhan, Beijing, Zhuhai, Changzhou, Foshan and Chongqing ranked among the top ten cities in China as popular camping tourist sources.

　　In Yang Songbai’s view, after the rapid recovery of cross-provincial tourism this year, camping and other popular tourism projects last year can still be continued, but we must make sub-products that meet the needs of consumers. "For example, some high-quality local tourism projects can be retained, but they can be combined with inter-provincial RV camping, travel agency channel marketing and local homestays to make domestic tourism products. Nowadays, there are many young guests who like to drive by car, experience special homestays and travel freely. We must understand their needs. " Yang Songbai told the First Financial Reporter.

　　In addition to camping and RV tours, three years after the outbreak, a large number of consumers are paying more and more attention to health-related consumption, and healing tourism is one of them.

　　According to the survey results of CBN’s "Consumer Recovery, Will You Buy in buy buy?", more consumers have increased their spending in the health field this year, among which 87.18% of the respondents have a willingness to consume healthy food. It is worth noting that as many as 55.24% of the respondents are willing to participate in healing tourism this year, and 30.15% of the respondents have plans to participate in rehabilitation activities this year. It can be seen that healing tourism is a bright direction in the recovery of tourism consumption this year.

　　"The epidemic once pressed the pause button for our industry, but this year is definitely a business opportunity for recovery. There are two sides to everything. Although the epidemic situation has a great impact on the cultural tourism industry, it has also made more consumers pay attention to health care, and healing tourism has become a trend. The core products of the project "Yin Yu Shui Zhong Tian" invested and developed by us include the journey of mindfulness life, the series of trips of body and mind co-cultivation, etc. to help guests understand their physical and mental health, and also include service teams such as Chinese medicine practitioners, rehabilitation experts, health coaches and nutritionists. These holiday tourism projects combined with healing courses are very in line with people’s demand for recreational travel this year. This year, our key planning project is the Unity International Cultural Festival, to discuss with the industry how to cope with the challenges brought by the development of the times. This year, we will continue to deepen the health industry and continue to help promote the development of the big health industry. " Cao Weide, chairman of Wanbang Pan Asia Group and founder of Yinyu, said in an interview with China Business News.

　　It is precisely because of the warming of healing tourism that according to the data of Ctrip, Tongcheng, Mama Donkey, Flying Pig, Qunar, Tuniu, Mawei and Spring and Autumn Tourism, the heat of cities near and south of the Tropic of Cancer such as Sanya, Zhuhai, Xishuangbanna, Dali, Xiamen, Haikou, Tengchong and Beihai soared. Among them, the healing holiday tour in Sanya and some areas of Yunnan is the most popular. Yang Yang, general manager of Beijing Spring and Autumn Travel Agency, said that at the beginning of this year, many tourists chose to go to Sanya for "continuous recuperation", and most of these tourists were "Yangkang" tourists from North China. Spring and Autumn Tourism has also developed a variety of tourism products suitable for "Yangkang" treatment and recuperation, which directly boosted the recovery of cross-provincial tourism this year.

　　Opportunities and challenges of restarting outbound travel

　　Recently, for the tourism market, it can be said that there are frequent good news. First, it is pointed out in the government work report that restoring and expanding consumption are given priority. Increase the income of urban and rural residents through multiple channels. Stabilize bulk consumption and promote the recovery of life service consumption.

　　On March 10th, the Ministry of Culture and Tourism issued the Notice of the General Office of the Ministry of Culture and Tourism on the pilot resumption of the travel agency’s business of China citizens’ outbound teams to relevant countries (the second batch). According to the circular, starting from March 15th, 2023, the national travel agencies and online travel enterprises will be resumed on a pilot basis to operate China citizens’ outbound group tours to relevant countries (the second batch) and "air tickets+hotels" business. From now on, travel agencies and online travel companies can carry out preparations such as product release, publicity and promotion. List of countries involved in (the second batch of) outbound group tours: Nepal, Brunei, Vietnam, Mongolia, Iran, Jordan, Tanzania, Namibia, Mauritius, Zimbabwe, Uganda, Zambia, Senegal, Kazakhstan, Uzbekistan, Georgia, Azerbaijan, Armenia, Serbia, Croatia, France, Greece, Spain, Iceland, Albania, Italy and Denmark.

　　According to the survey results of CBN’s "Consumer Recovery, Will You Buy in buy buy", 32.37% of the respondents plan to travel both domestically and abroad this year. In other words, at least one-third of the respondents have the willingness to spend on this year’s outbound travel.

　　At the beginning of February this year, a number of outbound team tours started, mainly in the Southeast Asian market. The major overseas tourism bureaus have also started marketing for the China market in the near future. For example, the National Tourism Administration of Thailand originally planned to attract 5-6 million China tourists to Thailand this year, but after seeing the recent upsurge of China tourists’ enthusiasm for traveling to Thailand, it immediately raised its expected target. "In 2019, the number of tourists from China visiting Thailand was about 11 million, accounting for about a quarter of the total tourists in Thailand. According to the current good recovery momentum, we have raised our expectations. We now expect 7 million to 8 million China tourists to travel to Thailand this year." Yutasa, director of the National Tourism Administration of Thailand, recently revealed in an interview with the First Financial Reporter.

　　At the same time, Tourism Dubai, Tourism Australia, Tourism New Zealand and Tourism Singapore are all getting together for promotion.

　　"The further relaxation of outbound travel will inevitably play a positive role in the recovery of the tourism market this year. But we must also see the challenges faced by the recovery of the outbound travel market. For example, compared with domestic travel, outbound travel needs to go through a series of procedures, which are different according to the requirements of different countries, and some visa reservations need to be queued. Three years later, the local docking personnel in many outbound destination countries have also undergone great changes. For example, many local Chinese restaurants in Europe and America have switched to other formats, so it is very difficult to make a group meal of Chinese food now, and it is necessary to find a local catering business again. Local tour guides should also be re-docked. Moreover, many hotels in Europe have to book half a year or more in advance, and it is not easy to get a lot of rooms at once. The route of outbound group tour should also be redesigned, and the conflict between Russia and Ukraine has also led to various cost increases in some European tourist destination countries. International flights have not fully recovered, and these factors will make it take some time for some long-distance outbound travel in Europe and America to recover. To restart the docking of ground connection resources, we can foresee that the prices of some outbound travel products may double due to fewer flights and rising local costs. " Gu Wei, assistant general manager of Shanghai Airlines Tourism Group, spoke bluntly to the First Financial Reporter.

　　According to the questionnaire results of CBN’s Consumer Recovery, Will You Buy in buy buy, 57.39% of the respondents’ per capita spending budget for a single trip this year is 10,000-20,000 yuan, while 32.6% of the respondents’ per capita spending budget is 5,000-10,000 yuan. Judging from this, the per capita spending budget of the consumers interviewed this year is not low, even higher than in previous years.

　　Tourism enterprises pay attention to creating scenes and recruiting talents again.

　　In view of the positive recovery of tourism consumption this year, major tourism enterprises, scenic spots, hotels and other operators are gearing up. After three years of epidemic, most of the tourists are very sober and professional in this process &mdash; &mdash; Pure low price does not attract too many consumers, but to create attractive and cost-effective products.

　　"In the past, when people talked about tourism, especially group tours, it seemed that the cheaper the better, and this once caused many tourism disputes. Now what we see is that consumers are also mature, and everyone’s requirements for high cost performance of products are prominent. So what we need to do is to integrate the resources of scenic spots and major tourist destinations, and work with them to create some new products that meet the needs of consumers. This year, we will have plans to cooperate with some regional tourist attractions or local tourism-related operators to develop projects. We can participate in investment or act as operators, instead of the past travel agencies blindly serving as organizers to send tourists. " Liu Ning, director and president of Shanghai Jinjiang Tourism Holdings Co., Ltd., revealed in an interview with China Business News.

　　This is also confirmed in the questionnaire survey of CBN’s Consumer Recovery, Will You Buy in buy buy? In the questionnaire, what elements can promote consumption? Most respondents said that it was not low price, but high cost performance accounted for 93.9%, high-quality goods accounted for 90.85%, and value-added space accounted for 86.47%. It can be seen that the goods with high cost performance are the ones that consumers are most willing to spend money on, while the low price factor accounts for only 4.93%.

　　The Shanghai Tourism Industry Association revealed to the First Financial Reporter that in order to make more subdivided products and cost-effective products, it is necessary to pay attention to the creation of derivative scenes of Dawen Travel. For example, in the past, tourism was purely a trip, but now many tourism products can be combined with catering and culture, and some high-quality immersive experience projects and script projects can be created as consumption scenes of Dawen Travel. Of course, this kind of project development needs the cooperation of professional planning and cultural tourism resources.

　　Nowadays, Ctrip, Tongcheng Travel, Mahoneycomb, etc. are all strengthening cooperation with tourism destination resources, hoping to gather offline scenic spots, accommodation and other partners for common development. For example, recently, Tongcheng Travel announced that it intends to acquire Tongcheng Tourism at a total cost of no more than 700 million yuan. This is an attempt and layout of one-way travel in the leisure tourism and holiday market under the background of strong recovery of the tourism industry. At the end of December last year, Tongcheng Travel announced that it would acquire Tongcheng International Travel Service and promote the deep integration of its tourism and holiday business. The proposed acquisition of Tongcheng Tourism is a continuation of Tongcheng Tourism’s leisure tourism and holiday market. If this intentional acquisition can be achieved, it will effectively supplement and extend the existing business of Tongcheng Travel and deepen the control over the upstream core resources.

　　It is noteworthy that due to the three-year epidemic, some travel agencies and upstream and downstream partners still face problems such as resource shortage, and they urgently need support from traffic, technology, data and capital to seize the new opportunities of industrial rejuvenation. How to jointly promote the development of digital intelligence in the industry is a problem that should be considered.

　　In addition, the talent plan is also worthy of attention. Many tourism industry feedback, three years since the epidemic, many tourism practitioners have changed careers, this year’s consumption recovery, tourism recovery process needs a large number of professionals to help, which requires recruiting suitable candidates from college graduates and mature talents. Just recently, 10 companies, including Ctrip, announced the joint launch of the "Travel Mulan Plan", which plans to provide more than 20,000+jobs for women in 2023. Sun Jie, the co-founder of the plan and CEO of Ctrip Group, said that this move is to better meet the business growth demand in the first year of tourism recovery, and at the same time help more women get equal opportunities for development in the workplace.

　　Cheng Chaogong estimates that domestic tourism can be restored to 70% ~ 80% in 2019 this year, while Southeast Asia tourism in the outbound tourism market may be restored to about 70% ~ 80% in 2019. Of course, everything depends on the actual development of the market.

　　1. What is the meaning of "trade-in of household appliances"?

　　"Trade-in of household appliances" refers to the behavior of consumers selling old household appliances and buying new ones. Consumers sell five types of old household appliances specified by the state, such as televisions, refrigerators (freezers), washing machines, air conditioners and computers. After being recycled by the household appliance recycling enterprises determined by the tender, they obtain the nationally printed household appliance trade-in recycling certificate, and then purchase the above five types of new household appliances at the household appliance sales enterprises determined by the tender with the trade-in recycling certificate and the consumer’s valid certificate, and apply for the price subsidy for household appliances trade-in.

　　2. When will the city continue to implement the trade-in policy for home appliances?

　　According to the Letter of the Ministry of Commerce, the Ministry of Finance and the Ministry of Environmental Protection on Printing and Distributing the Work Plan for the Promotion of Household Appliances Trade-in and the Implementation Measures for Household Appliances Trade-in (Revised Draft) formulated by seven ministries and commissions, this Municipality will continue to implement the policy of household appliances trade-in after the end of the pilot period, and the implementation period is tentatively set as December 31, 2011. During this period, buyers who participate in the trade-in of household appliances in this city can apply for the price subsidy for the trade-in of household appliances in accordance with the regulations, obtain the recycling certificate for the trade-in of household appliances and purchase new household appliances from the successful home appliance sales enterprise.

　　3. Are there any restrictions on the types of home appliances that participate in the trade-in of home appliances?

　　The types of household appliances that can participate in the trade-in of household appliances during the promotion and implementation period of this Municipality are the same as those in the pilot period, and they are still five types of household appliances: televisions, refrigerators (including freezers), washing machines, air conditioners and computers. The state only subsidizes buyers who sell the above five categories of old household appliances and buy the above five categories of new household appliances, but the purchase of new household appliances is not subject to the corresponding restrictions on the types of old household appliances sold. For example, after the buyer sells an old TV and obtains the certificate of recycling household appliances, he can go to the successful home appliance sales enterprise to buy any of the five types of household appliances (such as refrigerators or washing machines), and can apply for price subsidies according to the prescribed standards.

　　4. What is the subsidy standard for replacing old appliances with new ones?

　　During the promotion and implementation period, the subsidy standard in the pilot stage is still used, that is, 10% of the sales price of new household appliances is subsidized, but the upper limit of the subsidy standard is limited for each type of household appliances. Among them, the maximum subsidy for TV sets is 400 yuan/set, for refrigerators (including freezers) is 300 yuan/set, for washing machines is 250 yuan/set, for air conditioners is 350 yuan/set and for computers is 400 yuan/set.

　　5. Is there any reference price standard for selling old household appliances?

　　Beijing Renewable Resources Recycling and Second-hand Goods Industry Association, after consulting with household appliances recycling enterprises and dismantling enterprises, referred to the residual value of resources after dismantling old household appliances and the costs of recycling enterprises and dismantling enterprises, and considered the public’s acceptance of the recycling price of old household appliances, formulated the reference price of recycling old household appliances and the integrity standard of main parts. The price is published by the association and clearly stated at various recycling outlets.

　　Hand in the old household appliances can choose the national household appliances trade-in policy or other ways to hand in the old according to the actual situation. The recycling price of used household appliances shall be determined through negotiation between the buyer and the recycling enterprise, and both parties may refer to this price standard when negotiating.

　　6. What should I do if the main parts are incomplete when selling old household appliances?

　　Handing over old household appliances should meet the integrity requirements of the main parts of old household appliances. If the old household appliances sold are short of major components, the household appliance recycling enterprise will reduce the purchase price as appropriate according to the lack of major components, and the specific recycling price will be determined through consultation between the recycling enterprise and the seller.

　　7. Is the subsidy object of home appliance trade-in in this city restricted by household registration?

　　The subsidy object of home appliance trade-in in this city is residents with Beijing hukou and legal entities registered in Beijing (collectively referred to as buyers above); At present, non-Beijing hukou personnel and non-Beijing registered legal entities cannot enjoy the subsidy policy of home appliances trade-in in this city.

　　8. Is there a quantity limit for buyers to participate in the trade-in of home appliances?

　　In the pilot stage, there is no quantitative restriction on buyers’ participation in home appliance trade-in. However, during the promotion and implementation period (from June 1, 2010 to December 31, 2011), according to the "Implementation Measures for Household Appliances Trade-in (Revised Draft)" formulated by seven national ministries and commissions, the number of individuals participating in household appliances trade-in, selling old household appliances and buying new ones does not exceed five; Legal entities participate in the trade-in of home appliances, and the number of old home appliances sold and new home appliances purchased does not exceed 50. Because the identity certificate of the purchaser who buys new household appliances and sells old household appliances must be consistent, when the number of new household appliances purchased with the recycling certificate exceeds a limited number, the part exceeding the limited number cannot enjoy the subsidy for buying new household appliances.

　　9. Are the new household appliances purchased by consumers and the old household appliances sold during the pilot period within the limit?

　　At present, the "Household Appliances Trade-in Management Information System" has shielded the records of purchasing new household appliances and selling old household appliances before June 1, 2010. Therefore, during the pilot period, the number of consumers who have purchased new household appliances and sold old household appliances is not counted in the restricted number. That is to say, if consumers have bought five new household appliances with the same ID card during the pilot period, but recalculated from June 1, 2010, they can buy at most five new household appliances.

　　10. What are the procedures for buyers to sell old household appliances and buy new ones?

　　(1) There are two ways for buyers to participate in the trade-in of household appliances in physical stores.

　　1. Participate in the trade-in procedure by "handing in the old before purchasing the new":

　　(1) The purchaser can apply for selling the old household appliances within the scope of the old-for-new subsidy to the winning recycling enterprise in the residential area through the Internet, telephone and other means, or can transport the old household appliances and sell them to the nearest household appliance recycling network;

　　(2) According to the ID card information provided by the purchaser, the household appliance recycling enterprise logs in the "Household Appliance Trade-in Management Information System" to check the number of used household appliances sold by the purchaser. When the number of used household appliances sold by the purchaser reaches 5, the purchaser shall be clearly informed;

　　(3) The home appliance recycling enterprise shall provide the old home appliance recycling service according to the requirements of the purchaser, and make an acquisition with reference to the published reference price of the old home appliance recycling during the promotion implementation period and the integrity requirements of the main parts of the old home appliance (if the main parts of the old home appliance are missing, the recycling enterprise may negotiate with the purchaser for pricing), and issue a nationally printed home appliance trade-in recycling certificate to the purchaser;

　　(4) The original and photocopy of the buyer’s trade-in recycling certificate and identity certificate (including ID card, household register, military officer’s card or soldier’s card that can prove the household registration in this city) (the legal entity must hold the original and photocopy of the business license and legal entity code certificate) to the successful home appliance sales enterprise to arbitrarily purchase home appliances within the scope of subsidy, and apply for price subsidy to the sales enterprise on site.

　　2. Participate in the trade-in procedures by "purchasing new products first and then handing over old ones":

　　(1) After the buyer goes to a home appliance sales enterprise with dual qualifications of home appliance recycling and sales, he should show the original ID card, and according to the tips of the staff, go to the service desk to inquire about the number of new and old purchases. When the number of new or old units has reached 5, the home appliance sales enterprise shall clearly inform the purchaser;

　　(2) After purchasing new home appliances, make an appointment with the home appliance sales enterprise to recycle old home appliances;

　　(3) When the sales enterprise distributes the new household appliances to the buyers, it will recycle and tow away the old household appliances according to the appointment, and issue the old household appliances recycling certificate to the buyers;

　　(4) The purchaser applies for price subsidies at the original home appliance sales outlets with the old home appliance recycling certificate, the invoice for purchasing new home appliances and the original and photocopy of the identity certificate.

　　(two) the purchaser through e-commerce enterprises to participate in household appliances trade-in procedures.

　　1. The purchaser applies for recycling old household appliances to an e-commerce enterprise with the qualification of exchanging old household appliances for new ones through the Internet (the information such as the category, brand, product manufacturer, model, serial number of the fuselage, seller’s name and ID number of the old household appliances should be listed in detail), and orders the selected new household appliances through the Internet;

　　2. According to the ID card information provided by the purchaser, the e-commerce enterprise logs in the "Household Appliances Trade-in Management Information System" to check the number of old and new purchases made by the purchaser. The e-commerce enterprise shall notify the purchaser when the purchaser has handed in the old ones or purchased five new ones;

　　3. E-commerce enterprises shall fill in the old household appliances recycling voucher and the Application Form for Home Appliances Trade-in Subsidy according to the above-mentioned information on trade-in and purchase of new ones, and arrange the distribution of new household appliances to buyers;

　　4. The e-commerce enterprise distributes the new household appliances to the buyer’s home, collects the payment at the full price, recycles and drags away the old household appliances of the buyer, and confirms the information of the recycling voucher with the buyer, and asks the buyer to sign the Application Form for Home Appliances Trade-in Subsidy and provide a copy of the ID card;

　　5. After reviewing the relevant subsidy information of the purchaser, the e-commerce enterprise will advance the payment for old household appliances and the price subsidy for new household appliances to the purchaser.

　　11. Why do buyers need to provide the original identification when selling old household appliances and applying for subsidies for new household appliances?

　　Because the country has set a number limit for buyers to participate in the trade-in of household appliances during the promotion and implementation period, if the number of used household appliances sold by individual buyers with the same ID card exceeds 5, the excess part cannot participate in the trade-in of household appliances. Therefore, buyers need to provide the original ID card when selling old household appliances, and recycling enterprises should log in to the "Household Appliances Trade-in Management Information System" of the Ministry of Commerce in time to check the number of old household appliances sold by buyers; When recycling, the recycling personnel should check the original ID card of the purchaser before filling out the recycling certificate of old household appliances.

　　In order to facilitate buyers to sell old household appliances, Beijing is divided into five recycling areas, and each recycling area has more than three household appliance recycling enterprises responsible for recycling old household appliances in that area (see the attached table for details). In principle, the buyer sells old household appliances to the nearest recycling outlets of household appliance recycling enterprises responsible for recycling in this area according to the place of residence; Household appliance recycling enterprises provide home recycling services for old household appliances according to the winning recycling area. In addition, enterprises with dual qualifications of selling and recycling can provide a "one-stop" service for sending new and old appliances, that is, buyers first go to the sales enterprise to buy new household appliances, and the sales enterprise recycles and drags away the old household appliances while sending them to the door. If the buyer carries and sells the old household appliances to the household appliance recycling enterprise by himself, it is not restricted by the region.

　　22. Can new home appliances that enjoy the subsidy policy of "home appliances going to the countryside" apply for trade-in subsidies again?

　　The Implementation Measures for Trade-in of Home Appliances (Revised Draft) clearly stipulates that new home appliances that have enjoyed the subsidy policy of "Home Appliances Going to the Countryside" shall not enjoy the trade-in subsidy repeatedly. Therefore, if the purchaser has purchased home appliances to the countryside and has applied for subsidies for home appliances to the countryside, he can no longer apply for subsidies for replacing old appliances with new ones.

　　23. Can buyers buy new home appliances before selling old ones?

　　Yes, but it can only be implemented in enterprises with dual qualifications of recycling and sales. That is, the purchaser can ask the enterprise to recycle the old household appliances while sending them to the door after the enterprise purchases the new household appliances. It should be emphasized that the home appliance sales enterprise shall not require the purchaser to purchase new home appliances before recycling old ones, and shall not set the time and standard for subsidizing the old-for-new certificates by itself.

　　24. How does the government strengthen the management of participating enterprises in the trade-in of household appliances?

　　In order to strengthen the management of the sales and recycling enterprises of trade-in household appliances, the Beijing Municipal Commission of Commerce and other seven departments have formulated the Detailed Rules for the Implementation of Trade-in Household Appliances in Beijing and its supplementary provisions. Signed "Household Appliance Trade-in Recovery Agreement" and "Household Appliance Trade-in Sales Agreement" with the successful home appliance recycling enterprises and home appliance sales enterprises; A performance bond of 100,000 yuan was collected from each successful bidder; Formulated the management regulations of trade-in vouchers and the penalty standards for breach of contract.
