After a long absence, the big screen is finally back!

  On July 16th, China Film Bureau issued a notice that cinemas in low-risk areas can resume opening in an orderly manner on July 20th, provided that all epidemic prevention measures are effectively put in place, while cinemas in medium and high-risk areas are temporarily closed. After the news came out, China fans immediately enthusiastically supported the resumption of cinema with practical actions, and pressed the "accelerate" button for the resumption of China’s film industry: on the first day of the resumption of cinema on July 20, the total box office of the national movies reached 3.5 million yuan, which is still growing in recent days. As of 19: 00 on July 23, the national cumulative box office has exceeded 18.85 million yuan. In addition to China, French, British, Singaporean, Malaysian and other countries have successively joined the "cinema resumption tide". Cinemas in various countries have taken a series of special prevention and control measures to ensure the safety of customers: Britain and France readjusted their cinema seating plans to ensure a safe social distance between audiences, and even dispatched the popular "Minions" to accompany you to the movies; South Korea’s CGV company has introduced a new "contactless cinema" model to reduce risks. During the epidemic period, in order to minimize the risk, various ways of watching movies have emerged: Wal-Mart will transform the parking lot into a drive-in cinema on a large scale, and "floating cinemas" have also emerged in Australia and the United States. You can also enjoy movies by boat on the Seine River. How beautiful it is.However, after 178 days of separation, we need to restart the agreement with cinemas step by step. The experience of returning to work and epidemic prevention measures of cinemas in various countries may help us to abide by various epidemic prevention requirements with awe and cherish this rare reunion time.

  Cinemas around the world welcome to return to work.

  The French is happy to buy old movies.

  Singapore’s movie experience is reassuring.

  The attendance rate of Malaysian cinemas is less than one third.

  With the epidemic situation stabilizing and all walks of life gradually returning to work, cinemas in many countries around the world that have been closed for several months have finally welcomed the first audience.

  On May 28th, local time, French Prime Minister Edward Philippe announced in a live TV broadcast that cinemas will reopen all over France on June 22nd. Since mid-March, in order to curb the spread of Covid-19, French cinemas have been closed, but now they can finally open again. In an interview with French 24 Hours, the cinema manager Louis Meyer said, "No words can express my feelings now. We have been waiting for 99 days."

  Although the cinema has reopened, it is unlikely to return to the state before the epidemic immediately. Because Hollywood and other production companies have postponed the release date of important films, there are no new films to be released in the cinema at first, so the audience will have to accept films with old themes like De Gaulle. Charles de Gaulle is a biographical film about French wartime leaders. During the epidemic, the release was interrupted because of the blockade of cinemas. However, Lisa Nesselson, the cultural editor of 24 Hours in France, thinks that this situation will not dampen the French’s enthusiasm for going to the cinema. On June 22nd, she said: "France can be said to have a real advantage in the reopening of cinemas around the world, because 40% of the 6,000 projection rooms in France are from art galleries, which means that the French is very willing to buy old movies."

  France is one of the countries that love movies most in the world. According to a previous poll, 18.7 million people plan to go to the movies after the cinemas return to work, which accounts for almost one third of the total population of France.

  In addition to France, on June 3rd, Singapore Information and Communication Media Development Board also announced that cinemas in Singapore could reopen on July 13th, but cinemas must take necessary preventive measures to control risks related to novel coronavirus. These measures include: readjusting the seats in cinemas, ensuring a safe distance of at least one meter between customers, allowing family members or friends in the same industry to sit together but not more than five people, controlling the number of people in each screening hall to be less than 50, and taking measures such as distancing themselves from queues and other crowd management.

  Although most Singaporeans think that the protection measures for cinemas are very thorough, some people have made other preparations for safety. In an interview with Singapore’s Today newspaper, Ms. Wang said that she would avoid eating in order not to take off her mask. Mr. Kong, the designer, said in an interview that he would choose to go to the cinema on weekdays to avoid the crowd. Another movie lover, Ben Soh, agrees with this view and says that he would prefer to watch movies on weekdays because it is neither crowded nor safer.

  Mr. Ben Soh has just finished watching The Bridge Curse in Singapore Cinema, and he commented that the viewing experience was reassuring because all the safety measures were strictly put in place.

  After more than 100 days of business suspension, cinemas in Malaysia reopened on July 1. Although there is no new film released, many viewers still choose to return to the cinema to watch the movie live to support the box office, and the operators are deeply grateful for this.

  On July 16th, a spokesman for MBO Cinema said in an interview with Malay Post that the selling rate of movie tickets is slowly increasing. In the past two weeks, the average attendance rate was between 15% and 25%. He said: "At present, our strategic plan is to operate at the optimal level first, and then we will recover the indirect expenses of the cinema in the next few months." However, the spokesman also admitted that how to gain the trust of customers under the new normal and how to solve the problem of lack of new movies brought about by the epidemic are severe challenges for them.

  prevent epidemics

  Safety should also be ensured when returning to work.

  Encourage advance booking of popcorn.

  "Minions" will accompany you to the movies.

  Trial operation of "Contactless Cinema"

  Although cinemas all over the world have gradually joined the ranks of returning to work, as a gathering place, cinemas still need to take a series of prevention and control measures to ensure the safety of customers and staff during the special period when the epidemic has not completely ended.

  In Britain, cinemas in England resumed business on July 4th, while the opening dates of Northern Ireland, Scotland and Wales were set on July 10th, 15th and 27th respectively.

  The British Film Association has issued corresponding guidelines for this purpose, including:

  ● A certain social distance should be kept between seats, and people from different families should sit separately to limit the number of people in each screening hall;

  ● Stagger the movie playing time, so as to avoid the hall being crowded;

  ● Hand sanitizer and extra cleaning work need to be provided, and employee training should be actively organized;

  ● Encourage people to book online as much as possible, and use electronic tickets and contactless payment;

  ● The sales mode of mixed snack packages will be cancelled, and consumers are encouraged to book popcorn in advance.

  In addition, cinemas will also implement special seat selection schemes. Admit One, which provides ticketing services for ordinary cinemas and multi-hall cinemas, said that when customers book tickets online, the system will automatically generate "bubbles" on the seats around them to maintain a safe social distance. Some cinemas may not allow consumers to choose their own seats, because this may affect the occupancy rate of cinemas.

  Admit One also said that the average width of a seat in a cinema is about 60 cm and the depth is about 97 cm. Therefore, in order to meet the requirement of "2 meters interval between seats", the cinema must leave 12 empty seats around an audience and 16 empty seats around a couple. However, if the social safety distance is 1 meter, cinemas can choose other configuration schemes, but most cinemas can only accommodate customers with about half the seats.

  In France, when going to the cinema, there are no longer "empty" seats around, but those lovely "Minions" dolls. In 2015, these yellow drug-shaped toy figures first appeared in front of the French in the cartoon "Minions" shown in MK2 cinema in the south of Paris. This year, "Minions" wore iconic goggles and work clothes, solemnly "sat" next to the audience, forcing them to leave a safe distance. Cinema trips are not the first time that "Minions" people have been recruited to protect the safety of the audience. They have also appeared in the short public service advertisements jointly launched by the World Health Organization, the United Nations Foundation and lighting and entertainment companies, vividly sharing with the world how to protect each other and protect the community in this epidemic.

  Nowadays, chain cinemas in South Korea are also "racking their brains" to plan new plans, hoping to make fans come back to the cinema more comfortably and safely. CJ-CGV, the largest cinema in South Korea, has launched a "contactless cinema" mode in a sub-cinema in Seoul, where popcorn, hot dogs and soft drinks are moved into vending machines, while other snacks are placed in the sales office and delivered through contactless boxes. Two roving robots have replaced the ticket sellers, and you can know the movie screening time and other cinema information through the touch screen on the robots.

  "This is more hygienic than face-to-face communication, customers will feel safer, and this way is more interesting and cool." Li Seung-soo, an employee of CGV, told VOA. He also said that before the COVID-19 epidemic forced enterprises to take social or physical isolation measures, CGV Company was already considering introducing some automation facilities for cinemas, and the urgency of epidemic prevention eventually led to the emergence of the "contactless cinema" model. In addition, CGV cinemas will regularly disinfect the cinema facilities and leave enough safe space between the audience.

  "This contactless cinema mode of the branch is still in the testing stage." Li Shengzhu added, "According to the progress of this project, we will decide whether to introduce this kind of service in other theaters."

  Coup

  There are many fancy movie theaters.

  Drive-in theaters are sought after again.

  Floating cinema has a unique style.

  Romantic viewing on the Seine River

  In addition to watching movies in cinemas and at home, the epidemic has also spawned a variety of ways to watch movies, and the back-favored drive-in cinema is one of them.

  Drive-in cinema is a special form of cinema, which consists of a large outdoor movie screen, a projector, a snack bar and a parking lot. Fans can watch the big screen in their car and listen to the movie sound on the car radio. During the epidemic period, drive-in cinemas rose again all over the world because of their unique advantages such as privacy and security. According to the latest data from measurement company Comscore, the number of drive-in cinemas in Britain has soared from 3 to 40.

  In the United States, as part of its cooperation with Tribeca enterprises, Wal-Mart will turn its 160 parking lots into contactless drive-in cinemas from August, which will increase the total number of drive-in cinemas in the United States by at least 50%. "Since we held the Tribeca Film Festival 19 years ago, the drive-in cinema has been a landmark project in Tribeca." Jane Rosenthal, founder of Tribeca Enterprise, said in a statement, "Tribeca drive-in cinema is not only an interesting and nostalgic way to watch movies, but also one of the safest ways for people to gather. We are very happy to cooperate with Wal-Mart to bring more people together and share this special movie-watching experience. "

  The drive-in cinema will last until October this year, covering a total of 320 movies. The specific list of movies to be shown is yet to be determined, but Wal-Mart said that movies suitable for families and "special appearances of filmmakers and other celebrities" will be included.

  Wal-Mart is not the only company that has converted its parking lot into a cinema. The Marcus chain cinema in the midwest of the United States has also launched a drive-in cinema project this year, and has formulated a series of epidemic prevention measures to ensure the safety of the audience. The cinema emphasizes that sick people should stay at home, and customers who choose to watch movies should also wear masks in the cinema lounge or when collecting coupons.

  If you think it’s a little depressing to watch movies in such an airtight car, you might as well try to get some fresh air on the boat.

  Beyond Cinema, headquartered in Sydney, will set up water cinemas in many cities in Australia and the United States, so that the audience can enjoy the scenery while watching movies.

  "The cinema will consist of 12 to 24 mini-boats, each of which can accommodate up to 8 people." Beyond Cinema official website’s registration page shows, "You will need to pay the ticket price of the whole boat to ensure that only family and friends can sit together, thus maintaining the social distance between the boats."

  New york’s water viewing time is scheduled for one week from September 16th to September 20th this year. The specific movie playlist has not yet been announced, but officials say both classic old movies and new movies will be covered.

  Beyond Cinema is not the only organizer of "Floating Cinema" — — On the banks of the Seine in France, the "Paris Beach Festival" also held a grand water viewing ceremony.

  The "Paris Beach Festival" is an activity held in France every summer. During the event, some areas along the banks of the Seine will be paved with sand to form artificial beaches, providing Parisians with a place to relax.

  This year, Paris cooperated with MK2 Cinema to hold a water viewing celebration. On July 18th, the audience can choose to watch the French comedy "The Grand Bath" on an electric boat or on a chair on the river bank. Elisha Karmitz, CEO of MK2 Cinema, said in an interview with Euronews: "After several months of city blockade, we think we should find a suitable way to tell people and the world that the cinema has reopened in Paris, the movie capital of the world."

  industry

  The way to survive after the epidemic

  Although the reopening of cinemas paved the way for the release of new films, and the fancy viewing mode also provided new ideas for the development of the industry, we still can’t ignore the heavy blow suffered by the film industry during the epidemic.

  On March 4th, 007 official Twitter announced that the series "007: No Time to Die" originally scheduled for release in April will be postponed to its premiere in November, which is the first Hollywood film in North America to be postponed due to the epidemic. Changing the release date is undoubtedly a huge loss for the film, which means that huge publicity expenses have hit Shui Piao, which is like the first stone thrown into the water, causing ripples in the film circle. On April 4th, Mulan announced that the release date of the film would be postponed from March 27th to July 24th, while Tenet, which was originally scheduled to be released in July, was also postponed to August due to the epidemic, and this date was postponed again recently.

  According to the Guardian, director Nick Rowland’s first film "Rest on a Horse" was originally scheduled to be released on March 27th, but as the release date approached, he felt more and more anxious. "Around January and February, I noticed the news that the COVID-19 epidemic began to spread in Europe. I suddenly realized that when" Leaning on a Horse "was released, it happened to be the most serious moment of the London epidemic. What would you do in this case? I’m ambivalent, but it’s too late to postpone the release now, so we have to promote it. But at the same time, we have to advise our family and friends to stay at home and watch movies instead of going to the cinema. It took me six years to shoot this film, but I only got a few days to show it, which is really unacceptable. "

  On June 19th, the British Film Association and the Film Publishers Association organized a film industry recovery plan called "Restarting Cinema: Content Recovery" through the cross-industry group "Cinema First", and created a huge film library of 450 films including Hollywood classics, independent films and modern blockbusters to help cinemas recover quickly after several months of suspension. Andy Leyshon, CEO of the British Film Distribution Association, said: "We value you, we miss you, and this time we support you with some really great movies."

  Film production around the world is still in a state of stagnation, and films such as Avatar sequel and Jurassic World: Sanctuary The Matrix 4 have been forced to suspend production due to the epidemic. According to the data of statista information platform, as of mid-March 2020, the revenue loss of the global film industry has reached 7 billion US dollars, and it is estimated that this figure is likely to increase by another 10 billion US dollars in April and May.

  In order to alleviate the pressure brought by the cancellation of the premiere, the closure of cinemas and the sharp drop in box office, film companies are constantly seeking new profit growth points, and the streaming media platform has become their target. Disney+is a streaming media service platform launched by Disney. During the period from February to May this year, the number of subscribers of the platform has doubled to more than 50 million. Trolls World Tour, the new film of Universal Pictures, directly crossed the cinema and implemented the online on-demand mode. In the first three weeks of its release, it achieved nearly $100 million in revenue, exceeding the income generated by the first film "Magic Hair Wizard" in the cinema for five months. Moreover, the film company will get a higher percentage of revenue rebate if it chooses to release online, which is about 80%, while the cinema release is only 60%.

  Italy’s Circuito Cinema combines online and offline broadcasting, and launched a transactional video-on-demand platform plan called MioCinema on May 18th. On this platform, viewers can pay 7 euros to watch a movie online, and 40% of each online payment can be used to buy movie tickets for cinemas that are still closed. But when the epidemic is stable and everything returns to normal, the cinema and streaming media will be separated again.

  Although the online platform seems to provide a virtual space where movies can be played permanently, various video websites, the projection of the living room at home, and the computer screen that can be fast-forwarded at any time can’t replace the touching silver screen. Many fans are still eagerly looking forward to returning to the cinema and completely immersing themselves in the beautiful light and shadow outside ordinary life in the "dark" space. Richard Linklater, an American producer, said in an interview in The New York Times: "This is a common dream, starting with filmmakers and ending with the audience, in a space that is now regarded as more fragile, where we all agree to get together quietly."

  Before a cinema in San Francisco closed down, it left a message on the sign at the door, "Keep healthy and safe, and then we will come back soon."

  This is also the deep expectation of all people who love movies. This edition/Zhangyuan

Strategic analysis and enlightenment of ExxonMobil’s biochemical business development

  Fu kai mei Xue Jing China petroleum & petrochemical research institute

  At present, global petroleum and petrochemical companies are accelerating the pace of low-carbon transformation, and biochemistry has become one of the key areas of common concern for all companies. ExxonMobil, as the world’s leading integrated upstream and downstream oil company, has advantages in resources, technology, market and other aspects. Many years ago, ExxonMobil took biochemistry as a part of its business layout and achieved certain results.

  Development course of biochemical business

  According to different business positioning and development priorities, the development of ExxonMobil’s biochemical business can be roughly divided into two stages.

  The first stage (2009— 2016): Forward-looking layout. Exxonmobil believes that microalgae is a more potential raw material for producing biofuels in the future compared with corn and straw, so it takes the third generation biofuel based on microalgae as the entry point for the company to enter the biochemical field, and invests a lot of money in key layout. In 2009, ExxonMobil invested $600 million to develop microalgae biofuels in cooperation with the biotechnology company Synthetic Genomics. In 2015, we invested USD 1 million to cooperate with Michigan State University to improve the production efficiency of algae oil and microalgae products. In addition, we also cooperated with Colorado University of Mining and Technology to conduct basic research on algae photosynthesis and carbon sequestration.

  The second stage (2016-present): strategic adjustment. After more than 10 years of exploration in the field of microalgae biofuels, ExxonMobil believes that this technology is still far from industrialization (it will only be competitive when the price of crude oil reaches 500 US dollars/barrel), and then its layout will focus on the second generation biofuels with agricultural and forestry wastes and waste oils as raw materials. The company has stopped investing in the microalgae project of Colorado University of Mining and Technology and the biotechnology company Viridos (formerly known as Synthetic Genomics). At the same time, cooperate with REG, a renewable energy group, to study the production of biodiesel from agricultural wastes; Cooperate with Colijn Company to expand raw materials to different kinds of cellulose; Acquisition of a 49.9% stake in Biojet, a Norwegian biofuel company, to enhance the supply capacity of biofuels.

  Strategic analysis of biochemical business development

  Since 2009, although the development of global liquid biofuels once fell into a trough, ExxonMobil has kept its biofuel business in several business restructurings, and explored the technology of making biofuels and biochemicals from different biomass raw materials. Its development strategy has the following three characteristics.

  First, relying on its own development orientation and advanced layout, biofuel technology is taken as the breakthrough point of biochemical business layout. Because the fuel business is the absolute advantage of ExxonMobil, it chose to start from this field when laying out its biochemical business, and turned its eyes to microalgae with more potential in the future to become a leader in this field. Recently, although the focus of ExxonMobil’s layout has shifted, it is still based on the fuel field, and its target is mainly the second-generation biodiesel and sustainable aviation fuel with supply gap in the current market. In terms of technical route, it has developed the second generation biodiesel production process based on cellulose biological enzyme conversion, which has been successfully applied to automobiles and heavy trucks; The pretreatment of forest waste based on traditional chemical transformation — Gasification — Fischer-Tropsch synthesis process can produce the second generation biodiesel and sustainable aviation fuel. In addition to cooperative development, ExxonMobil also increased the supply of low-carbon fuel through mergers and acquisitions of mature enterprises and procurement.

  Second, based on the breakthrough in biofuel production, it gradually expanded to the research and exploration of raw materials and products. On the one hand, ExxonMobil continues to expand the range of raw materials and explore the feasibility of vegetable oil, waste cooking oil, alcohol and carbon dioxide as sustainable raw materials. For example, converting biomass and waste into renewable methanol to produce sustainable aviation fuel; Convert the captured carbon dioxide into sustainable aviation fuel. On the other hand, we will expand product varieties and develop bio-based lubricant base oil and other products besides biodiesel and sustainable aviation fuel. For example, we cooperated with the University of Wisconsin to carry out a joint research project on biomass upgrading technology to increase the added value of bio-based products through further reaction.

  The third is to take rapid breakthrough as the development goal and adopt different R&D models based on its own R&D foundation. ExxonMobil’s bio-fuel technology route is mainly divided into two categories: one is bio-refining technology route based on traditional refining, and the other is industrial biotechnology route based on fermentation and enzyme catalysis. For the former, ExxonMobil has accumulated profound research, focusing on independent research and development. Aiming at the utilization of biomass raw materials such as vegetable oil and restaurant waste oil, it developed proprietary technology EMRD^TM and dewaxing catalyst BIDW^TM. By hydrodeoxygenation and isomerization of triglycerides, the second generation biodiesel (or sustainable aviation fuel) was obtained, and the product had good low-temperature fluidity. For industrial biotechnology, ExxonMobil mainly develops through cooperation with mature companies and universities. For example, we cooperated with REG and Colijn Company to produce biodiesel from renewable cellulose sugar from fermented agricultural wastes, so as to improve the conversion rate and biodiesel yield.

  Suggestions to China’s petroleum and petrochemical companies

  In May, 2022, the National Development and Reform Commission issued the "Tenth Five-Year Plan for Bio-economic Development", which put forward the objectives of bio-economic development and defined four key development areas, including the substitute application of biomass, and pressed the acceleration button for the development of biochemical industry. By analyzing the development experience of ExxonMobil, the following three suggestions are put forward for the development of biochemical business of China’s petrochemical companies.

  First, seize the opportunity of the times, coordinate the overall layout of the company’s business, and do a good job in top-level design. China’s petroleum and petrochemical companies should seize the opportunity period of bio-economy, base on the company’s goal of low-carbon development and energy transformation, and combine their own development characteristics and foundations to select and focus on appropriate biochemical business segments, such as biofuels or bio-based chemicals. Coordinate and optimize the overall layout of biochemical business and its existing business, do a good job in top-level design and formulate practical implementation paths, give full play to the advantages of biochemical technology such as negative carbon attributes, high reaction efficiency and reduced dependence on crude oil, and help the company to transform into a green and low-carbon company.

  Second, in the early stage of new business development, expand open cooperation and technology introduction to seize market opportunities. For China’s petrochemical enterprises, compared with the traditional refining and chemical business, the biochemical business is relatively new. When entering a new field, we can refer to ExxonMobil’s development strategy, speed up technological breakthrough by cooperating with leading enterprises in the industry or introducing technology, realize the large-scale application of key biochemical technologies as soon as possible, and seize market opportunities. For example, relying on the company’s existing technology and equipment, biomass oil products with relatively stable quantity and properties can be obtained through cooperation with biomass oil producers to replace part of crude oil and produce biofuels and bio-based chemicals with mixed feed.

  Third, when the business development enters a mature stage, strengthen the forward-looking technology reserve and create a competitive advantage. At present, global scientific and technological innovation has entered an unprecedented intensive active period, and new technologies such as synthetic biology and gene editing are reconstructing the competitive pattern of various industries. With the biochemical business of China’s petrochemical companies on the right track, it is suggested that they closely follow the development trend of scientific and technological innovation in the field, rely on the company’s existing technological innovation system, focus on the bottleneck and demand of industrial development, start with basic research, develop forward-looking technology and subversive technology reserves, and strengthen the protection of intellectual property rights of related technologies to create new competitive advantages in the biochemical field.

Scientists make glass "rejuvenate"

  ◎ Intern reporter Li Zhao Yu Dou Peng

  From towering skyscrapers to small and exquisite chronograph watches, glass can be seen everywhere in life.

  Peng Shou, deputy to the National People’s Congress, academician of China Academy of Engineering, chief engineer of China Building Materials Group and president of China Building Materials Research Institute of Glass New Materials, said in an interview that it is necessary to vigorously promote energy conservation and carbon reduction in the glass industry, so that the glass industry in China can "go green".

  In fact, glass should not only "go green", but also be expected to "rejuvenate" — — With the increase of service time, glass will age, which is usually accompanied by the deterioration of physical and mechanical properties. In recent years, more and more attention has been paid to how to "rejuvenate" aging glassy substances and restore their properties.

  At the end of 2022, Jiang Minqiang, a researcher at the Institute of Mechanics, Chinese Academy of Sciences, revealed a new mechanism for the rejuvenation of severely aging metallic glass through research, which deepened the understanding of the rejuvenation of glass structure. Relevant research results were published in Fundamental Research, a multidisciplinary English journal headed and sponsored by the National Natural Science Foundation of China.

  Glass aging: a slow transition from disorder to order

  To make glass "rejuvenate", we must first understand how glass "ages".

  Jiang Minqiang introduced that from a microscopic point of view, glass is an amorphous solid with irregular structure. He gave an example to the reporter: in crystalline solids such as steel, atoms are arranged in an orderly manner like students sitting quietly in a classroom, showing a regular shape. In glass, an amorphous solid with irregular structure, atoms are just like students after class, running around the campus, showing a disorderly arrangement.

  The phenomenon of glass aging, in essence, is the transition of glass from the disordered state when it was initially formed to the orderly state. "Generally speaking, the total energy of matter is higher in disorder state, while in order state, the total energy of matter is lower. As time goes on, glass will gradually change from a high-energy state to a low-energy state. This process is generally called glass aging. " Jiang Minqiang explained that if the aging time is long enough, or the aging is accelerated by heating up, the glass can even be transformed into a solid crystal with a regular structure.

  Glass aging will affect many properties of glass, such as toughness, optical properties and electrical conductivity, which is a phenomenon that people want to delay or even avoid. Therefore, as a process of reversing glass aging, glass rejuvenation has long been widely concerned by researchers.

  "The rejuvenation of glass is the reverse process of glass aging, that is, the glass that makes the atoms relatively orderly after aging slowly returns to the relatively disordered state of atoms." Jiang Minqiang said. In the previous research on glass rejuvenation, the researchers found that the younger glass will release some enthalpy when it is heated to a certain temperature, and the higher the younger the glass is, the more enthalpy will be released during heating. Enthalpy is an important state parameter to characterize the energy of material system. Generally speaking, enthalpy is the energy released by young glass during heating.

  "Our research believes that the above views do not apply to severely aging glass. With the increase of the degree of youthfulness, the enthalpy release of severely aged glass has not changed, or even has no enthalpy release at all. " The research of Jiang Minqiang’s team shows that the previous views on glass aging mechanism are not applicable to severely aging glass, which updates people’s understanding of the mechanism of glass structure rejuvenation.

  "Unintentionally inserted willow": The research result is unexpected.

  "In fact, the breakthrough of this research stems from our research team ‘ Unintentionally inserted willow ’ An attempt. " Jiang Minqiang said that the initial purpose of this experiment was only to prepare experimental samples. "Our team originally prepared samples for another experiment. In order to strengthen the scientific nature of the experiment, it is necessary to eliminate the thermal history of the samples and ensure that their structures are consistent. We anneal the glass samples at low temperature — — Slowly heat the metallic glass to a certain temperature and keep it for enough time, and then cool it to room temperature at a certain speed. " Subsequently, the research team rejuvenated these glasses in a severely aging state through mechanical deformation. The result was unexpected — — "We obviously input energy into the glass through mechanical work. Why don’t these glasses release enthalpy and become younger?" This is contrary to the previous mainstream view.

  This result puzzled the research team. In order to solve the mystery, in addition to measuring enthalpy, the research team also measured the high temperature of glass samples (450K— 750K) and low temperature (1.9K— 100K), and then the atomic vibration information and topological structure information of glass are investigated. "In the course of the experiment, the research team found that although the parameter of enthalpy release before glass transition remains unchanged in some cases, the effective enthalpy change during glass transition and the atomic vibration Bose peak reflected by low temperature specific heat will change accordingly." Jiang Minqiang further explained, "This shows that enthalpy release is not the only physical quantity reflecting the rejuvenation of glass."

  When talking about why the enthalpy release remains unchanged, Jiang Minqiang once again explained with vivid examples: "If we put a ball in ‘ Concave ’ The concave part of the zigzag plane, this ball will naturally remain in place. This stable state is like severely aged glass. And if we put this ‘ Concave ’ The zigzag plane is inclined at some angles. Although the height of the recess, that is, the energy level of the glassy substance, remains almost unchanged, the glass state represented by the ball will become unstable, and then the phenomenon of glass rejuvenation will appear. "

  The results show that, in addition to the previous mainstream point of view, the rejuvenation of glass can be directly reflected in the release of enthalpy, that is, the improvement of energy level, and can also be reflected in the inclination of energy plane, that is, the free volume can be redistributed in space through local structural rearrangement. "This is also the new mechanism of rejuvenation of severely aging glassy substances that we have discovered." Jiang Minqiang said.

  Expand the scene: provide a broad application space

  This study also found that with the glass entering a steady flow state, the above three physical parameters representing the rejuvenation will tend to saturation values, so it was first determined experimentally that the upper limit of the glass structure rejuvenation was a "frozen" steady flow state.

  If water is used as an analogy, glass that forms liquid at high temperature is like water, while glass that solidifies at low temperature is like ice. "The limit of the rejuvenation of the glass structure is that the high-temperature glass liquid is suddenly frozen by rapid cooling, thus forming a similar ‘ Frozen running water ’ The material state. " Jiang Minqiang explained, "In this case, the glass will maintain almost the same material structure as the liquid state under the solid appearance, and its fluidity will reach the limit of current understanding."

  The new mechanism of rejuvenation of glassy materials revealed in this study not only allows us to better understand the related causes and processes of glass aging in physical essence, but also has great potential application space in promoting the batch rejuvenation of aging glass. "The research team is currently communicating with companies engaged in glass production or research and development, trying to find a good combination point to promote technology to the market."

  In addition, Jiang Minqiang also found that the new mechanism revealed in this study is also expected to be applied to the preparation of advanced metal materials.

  "Generally speaking, the strength and toughness of metal materials cannot be both. With the increase of strength, toughness will decrease, and vice versa. " Jiang Minqiang said, "How to overcome this inherent inversion relationship is a problem that must be faced in preparing advanced metal materials with both strength and toughness."

  The total energy level of high-strength metal materials at the microscopic level is generally very low. If energy is input by heating and other methods, it is almost impossible to try to improve the toughness of metal materials by raising the total energy level, which often requires extremely high energy input.

  "If we can use the new mechanism discovered in this study to adjust the energy plane angle of metal materials when the total energy level is low, we can improve the disorder of atoms and enhance the toughness of metal materials while maintaining the macro strength unchanged. Through this method, we can effectively avoid huge energy input and greatly reduce the cost of preparing high-toughness metal materials. " Jiang Minqiang said that his team is constantly trying to make a decisive breakthrough and provide new ideas for solving the irreconcilable contradiction between the strength and toughness of metal materials for a long time.

Review of weekend news: the central bank set up 300 billion yuan of guaranteed housing refinancing.

  Macroeconomics > > >

  The People’s Bank of China plans to set up a re-loan for affordable housing: the scale of 300 billion yuan can be extended for 4 times.

  On May 17th, the People’s Bank of China announced that it planned to set up affordable housing refinancing. The refinancing scale is 300 billion yuan, the interest rate is 1.75%, the term is one year, and it can be extended for four times. The distribution targets include 21 national banks including China Development Bank, policy banks, state-owned commercial banks, Postal Savings Bank and joint-stock commercial banks. In accordance with the principle of independent decision-making and risk-bearing, banks issue loans to local state-owned enterprises selected by the city government and purchase completed unsold commercial houses for affordable housing. The People’s Bank of China will issue re-loans according to 60% of the loan principal, which can drive bank loans of 500 billion yuan. Tao Ling, deputy governor of the People’s Bank of China, said at the policy briefing in the State Council on May 17th that the decision was no longer to set the lower limit of interest rate policy for first-home and second-home loans at the national level. For first-tier cities and some hot cities, the city government can still decide the lower limit of local mortgage interest rate policy according to local conditions. If the relationship between supply and demand in the real estate market changes greatly in the future, the People’s Bank of China will promptly resume the implementation of the policy lower limit or guide the city government to resume the policy lower limit to regulate supply and demand. After canceling the lower limit of the mortgage interest rate policy, commercial banks can decide the interest rate level independently according to the customer’s risk situation to realize the marketization of mortgage interest rate.

  Economic Daily: Real estate credit policy is further optimized.

  The Economic Daily article pointed out that the People’s Bank of China issued a number of notices, explicitly canceling the lower limit of mortgage interest rate at the national level, lowering the mortgage down payment ratio and provident fund loan interest rate, and launching the refinancing of affordable housing. Experts believe that the new round of support policy is the continuation and expansion of the previous real estate credit policy, further enhancing the financial support. The reporter learned from the central bank that by the end of April this year, 67 of the 343 cities in China had cancelled the lower limit of the first home loan interest rate. Financial institutions reported that after the lower limit of mortgage interest rate in these cities was abolished, the interest rate declined to some extent, but after full competition, the market formed a new and relatively stable equilibrium level, which played a driving role in the local new mortgage issuance. Market experts predict that after this policy adjustment, more cities will cancel the lower interest rate limit, and the independent pricing space of some hot cities that retain the local lower limit will also be significantly expanded. In the eyes of the industry, the future mortgage is still the best asset of the bank. It is expected that the implementation of the policy will lead to an increase in the new volume of bank mortgage, which can make up for the interest income from the decline in interest rates to some extent.

Putin is still the leader when he leaves office. People hope that he will remain in power and let the United States kneel down.

    Chairman of the United Russia Party talks about the future "birthright" of the President.


    Putin will remain a "national leader" after leaving office next year.


    □ Ou Ye (special feature of China Daily)


    "If Putin stays in power, we will make the United States kneel down"-a Russian government worker said. After the United Russia Party won the State Duma election, the future political identity and status of the current President Putin became the focus of attention.


    The chairman of the United Russia Party made it clear a few days ago that Putin will remain the leader after leaving office.


    USA-Today reported on the 6th that although Putin’s second presidential term will end in 2008, many people in Russia hope that he will remain in power because of his stable political situation and rapid economic growth.


    A 24-year-old Russian government statistics office worker said: "Russia is strong again. If Putin stays in power, we will make the United States kneel."


    Prior to this, Putin had said that he hoped to maintain his political influence after leaving the Kremlin. There is public opinion that Putin may amend the constitution to seek re-election, but Putin has repeatedly said that he respects the constitution and has no intention of amending it.


    The issue of Putin’s official "birthright" in the future has always been the focus of the United Russia Party, which won an overwhelming victory in the just-concluded Russian State Duma election. Gryzlov, chairman of the party, said: "Putin is our national leader. No matter what he will do after the presidential election, he will still be the leader of our nation."


    Some Kremlin officials analyzed that the results of the State Duma election showed that the mass base supporting Putin to remain in power was relatively broad, but the role of the so-called "state leader" could not be determined at present.

Old guns are happy with novices, and they can safely analyze the off-road configuration of tank 300.

  [Original by Aika Automotive Technology Channel]

  Tank 300 has been listed in China for some time. Although there have been several "hot searches" in cross-country circles, consumers’ enthusiasm for it remains undiminished. January was the first complete month after the listing of Tank 300, and its sales volume exceeded 6,000. This performance is even enviable. Some people say that this achievement has taken advantage of the withdrawal of foreign hard-core SUV models from the China market, but in my opinion, friends who play cross-country are often the people who know the most about cars. If there is no excellent product strength, Tank 300 will be "selling itself" again, and even no one will really place an order.

  Why does Tank 300 become a fragrant bun in the hearts of off-road fans? Some people say that it has a girder, some say that it has a differential lock, and others say that it is a technological configuration. In my opinion, it is difficult for a single product to form the excellent off-road performance of Tank 300. Only by combining these can the final Tank 300 be formed. So what excellent off-road configurations does it have?

Analysis of off-road configuration of tank 300

  If you ask the older generation of off-road players what a car can be regarded as a hard-core SUV, it will definitely give you three criteria, first, the non-loaded body structure (that is, the beam structure), second, the front and rear integral bridge suspension structure, and finally, the four-wheel drive system with differential lock. Therefore, herdsman, Toyota LC70 (series) and Mercedes-Benz G (old models) will exist in the hearts of off-road players like totems.

  With the development of consumer demand, the above three criteria are also changing. For example, the suspension structure has basically evolved into a front double wishbone rear integral bridge, which combines the dual needs of road and off-road, such as Toyota Prado, Land Cruiser and Mercedes-Benz G; The differential lock can also be added later; However, the non-load-bearing body structure remains unchanged, because it can ensure the strength of the body to the greatest extent when it is off-road, and the force is more dispersed when it is dragged.

Analysis of off-road configuration of tank 300

  There is no doubt that the tank 300 has all the three criteria mentioned above. First of all, the non-load-bearing body structure, after Haval H5 and Haval H9, the design of the tank 300 has become more mature. Ensuring a high-rigidity body structure is the main design feature of the tank 300. For this reason, the maximum cross-section of its longitudinal beam has reached 160mmx130mm, and there are 22 reinforcing plates for reinforcement, so there is no problem in meeting the conventional off-road requirements.

  In terms of suspension, the tank 300 uses the integral bridge structure with front double wishbone and rear five links, which is also the structure widely used by other hard-core SUVs, including Mercedes-Benz G, Prado, Land Cruiser and other models, except herdsman/Jimny. Its advantage is that it gives consideration to comfort and off-road performance to the greatest extent, and it also has excellent passing performance while ensuring road handling.

  Tank 300 adopts part-time 4wd system, which has the advantage of simple and reliable structure. Among them, 2H mode is high-speed rear drive, which is suitable for general paved roads. 4H high-speed four-wheel drive and 4L low-speed four-wheel drive are only suitable for unpaved roads because there is no central differential. In the 4L mode, the torque of the tank 300 will be amplified by 2.48 times.
