　　In the past few days, this newspaper has continuously reported the hot situation of live broadcast of goods on e-commerce platforms. Then, is the quality and safety of the goods that consumers buy in the live broadcast room excellent, and can the after-sales rights be guaranteed? Behind the booming live broadcast, how the platform and anchor should be self-disciplined and effectively supervised has become the focus of consumers’ concentrated attention.

　　The advantages and disadvantages of live broadcast products are in doubt.

　　"The price is indeed cheaper than the discount store, but the size and specifications are not the same as the genuine ones." Consumer Mr. Liu told reporters that when he was preparing to place an order to buy a well-known brand sports shoes in the live broadcast room of an e-commerce platform, he found that the 42.5-yard merchants he usually wore did not provide them, and all the optional sizes were integer sizes, and all the "half sizes" were not available. "There are genuine counters in all styles ’ Half size ’ Yes, so I feel that the shoes sold in this live broadcast room are still a bit uneasy. " The reporter learned in the interview that many consumers have doubts about the goods in the live broadcast channel. Mr. Wang, a consumer, said that he saw a mosaic toy during the live broadcast on the e-commerce platform. From the trademark to the packaging box and the theme content of the product set, it was very similar to a well-known brand. On the live broadcast interface, there were even less conspicuous subtitles that were compatible with the building blocks of well-known brands, and the sense of "cottage" was particularly obvious.

　　Is the "original ecology" product reliable?

　　Near the Spring Festival, many agricultural products from rural sellers are very popular in the e-commerce new year promotion activities. Reporters have seen products such as "rural autotrophic pigs", "earth eggs", "farm bacon" and "homemade honey" in the live broadcast rooms of many platforms, but are the quality of these so-called "original ecological" agricultural products directly from the fields really reliable, and is food safety guaranteed? When the reporter communicated with an anchor specializing in "rural autotrophic local pigs", he learned that all the pork, pig liver, pig lungs, etc. sold in the live broadcast room had not been inspected and quarantined. During the live broadcast, the anchor clearly told the reporter that if you want the quarantined pork, you can only go to the supermarket to buy it. The pork sold in his live broadcast room is "self-supporting by farmers" and is now slaughtered and sold without quarantine. In addition, the reporter also saw some bacon, honey, rice wine, etc. recommended by the anchor, which looked good in color and flavor, but it was impossible to know whether the production process and the use of ingredients and additives were standardized.

　　Anchor "self-discipline" can not be ignored

　　The reporter learned in the interview that with the increasing popularity of live broadcast, the "price tag" of some online celebrity anchors has gone up, especially the "head anchor" of live broadcast channels on several major platforms, and the price of live broadcast and anchor commission have been considerable. Therefore, data related to the live broadcast traffic and conversion rate of the anchor commission income are becoming more and more important. According to industry sources, in order to increase the price of the goods and the commission of the anchor, the situation of "brushing the bill" and "brushing the flow" occurs from time to time. This is untrue data for merchants, and to a certain extent, it constitutes false propaganda, misleading consumption, and even a deceptive behavior for consumers. These have become problems that consumers, manufacturers, merchants, platforms and anchors have to face. At the moment when the laws and regulations related to live broadcast delivery are still not perfect, the "self-discipline" of the platform and anchor is particularly important.

　　Our reporter Zhai Weilu

　　Cctv news(Reporter Zhu Chunyan) "If you don’t lose weight in March, you will be sad in April". Every year in March and April, it is a good time for gyms to engage in sales, but this year is different due to the epidemic situation. Will the gym that missed this spring usher in the peak season in May?

　　Wear a mask to keep fit.

　　On April 30th, Liu Jian, a fitness coach, finished exercising in his fitness studio and picked up disinfectant to kill bacteria. "I’m finally ready to welcome members". During this time, he always went to the studio to exercise alone, and then closed the door and left. He joked that it was spending tens of thousands of dollars every month to configure a luxury gym for himself. Liu Jian’s fitness studio is located in Chaoyang District, Beijing. It was closed during the epidemic and is expected to reopen in early May.

　　As the epidemic situation eased, many gyms opened one after another. Mr. Wu, the head of public relations for Super Orangutan, a chain fitness institution, told the reporter that half of the more than 100 classrooms of Super Orangutan in eight cities across the country have been approved and accepted by various places and started to resume business. During the epidemic period, the business should implement systematic epidemic prevention and control measures. When members enter the store, they must take temperature measurement, register their real names, check their health codes, etc., and increase store housekeepers to do cleaning, disinfection and hygiene management.

　　The reporter learned that many yoga studios in Beijing will also open for business. Phoenix Yoga staff said that after the class started on May 1st, the number of members in the class was strictly limited. Previously, the class that accommodated more than 40 people was changed to a maximum of 15 people, and members also needed to carry their own yoga mats to go to class. Yoga mats, towels, cups, etc. were no longer provided in the venue. She said that the venue has arranged to disinfect classrooms, auxiliary rooms, dressing rooms, public areas and toilets at regular intervals every day.

　　According to the Work Plan on Safe and Orderly Opening of Sports and Fitness Facilities in novel coronavirus during the Epidemic Period issued by Beijing Municipal Sports Bureau, at present, except swimming pools and underground sports and fitness facilities, other indoor sports and fitness facilities can be reopened.

　　Dapeng, the coach of an underground swimming and fitness venue in Beijing’s West Third Ring Road, told reporters that the membership card will be postponed. As for when the gym will open, the company is also waiting for a policy notice. Dapeng said that at this time in previous years, he would go out to hand out leaflets after giving lessons to members, "Learn about fitness swimming", but he has been unemployed at home since the Spring Festival holiday this year. Dapeng said that the company didn’t do anything during this time. "The boss has other business." In fact, he himself is not sure whether he can return to this gym to continue his work.

　　The life-saving straw "Cloud Fitness" will not stop.

　　On January 30th, the State Sports General Administration issued the Notice on Vigorously Promoting Scientific Fitness at Home, actively advocating scientific fitness at home. For each gym, driving home fitness has also become a lifeline for enterprises to survive.

　　The Music Carving Campaign, which focuses on private and small class teaching, has about 500 stores nationwide. After offline suspension, it spends tens of millions every month. Han Wei, the founder, predicted that the epidemic would cost Leke at least 100 million yuan, or even several times. During the Spring Festival, Han Wei assembled 100 employees to form a "death squad" to carry out online business, including recording and broadcasting small videos, live broadcasting and offering special courses, which were launched on platforms such as Aauto Quicker and Tik Tok. Yang Shuting, the public relations director of Leke, said: "Online live broadcast has broken the barriers of time and space and attracted a large number of users."

　　"Cloud Fitness" has become a must-have at home for a time. The super orangutan opened the "Super Scarlet Squat in the Home" on a live APP, and the number of online users in the first live broadcast exceeded 170,000, becoming the TOP1 anchor on a live broadcast. Mr. Wu, the head of public relations for Super Orangutan, said that with the arrival of the resumption of work, the number of viewers during this period was less than that in the early days, about 50,000 people per game, and many users have developed the habit of watching live exercises together.

　　With the growth of users, "cloud fitness" has not only become a lifeline for gyms, but also attracted a large number of giants from outside the industry. Alibaba Entertainment, Suning, etc. also joined their sports institutions to continuously launch videos and live broadcasts of fitness guidance on the online platform.

　　For fitness coaches, "cloud fitness" is a challenge, and it also gives them more room to play. During the epidemic, Keepland opened a "cloud small class" to allow coaches to start classes online in the form of a two-way camera. Coach Wang Wei said that he has never adapted to enjoying "small classes in the cloud" now. "Although his income is not as good as usual, he is more motivated to use his own training logic to attend classes."

　　Probe into the boundary of fitness industry

　　Although the income of online teaching is far less than that of offline courses, many insiders said that online exploration has cultivated people’s habit of online consumption, and offline is still the best fitness choice in the future, but online will also be indispensable. Online and offline access will become a new direction of the fitness industry.

　　He Wenyi, executive director of China Sports Industry Research Center in Peking University, believes that if the fitness industry wants to innovate and upgrade, it is necessary to seize the opportunities and challenges in the epidemic, or it may be eliminated. The so-called opportunity is that it is very important for the fitness industry to grasp the innovation of fitness content and products after the epidemic has made people pay enough attention to health.

　　The manager of a gym store in Beijing said that due to the epidemic, the physical store could not operate normally, but the company launched the "2020 Anti-epidemic Memorial Card" to upgrade and innovate its products. In addition, online celebrity Store was launched earlier to explore the fitness venues in the new media era, making it a lifestyle platform, a club and a new social place.

　　Han Wei, the founder of Leke, summed up the model of the gym into three versions: 1.0 model, opening a store to earn money from a store; 2.0 mode, establishing an online platform mode to connect users with offline gyms; 3.0 mode, after establishing the online platform, self-operated offline stores, "connecting people and goods yards, and making money offline".

　　In the post-epidemic era, fewer people may invite you to "learn about fitness swimming" on the street, but there may be more and more advertisements recommending you to "buy chicken breast" on the mobile APP.

Special feature of 1905 film network Have you ever wondered what it would be like if your memory disappeared one day?

We have seen too many movies, and we often meet people whose memories are fading away, and some incredible things have happened. Some people rely on their only remaining memories to find clues to solve crimes; Some people hit their heads and all their memories were restored; Some people can’t get their memories back all their lives.

On February 23rd, the movie officially released in the mainland cinema once again took the memory as a knife. However, this time it is a little different.

1 What’s the difference between this film?

The main characters in the film "Love Before Memory Dies" are two old people. Ella Spencer played by helen mirren is a rebellious old girl, while John Spencer played by donald sutherland is a forgetful old warm man.

The old couple are both seriously ill. John has Alzheimer’s disease, which we often call Alzheimer’s disease. The disease makes his memory go wrong and slowly disappears. He needs to live in a nursing home, while Ella has cancer and needs to be admitted to the hospital. At this moment, the two will face eternal separation.

So, the two decided to take a trip in an RV. The English name of the film "The Leisure Seeker" is the name of this RV — — Leisure seekers. They walked all the way from Massachusetts to the south, recalling the experience of spending their holidays with children. This time, their destination was Hemingway’s former residence on Sisuo Island.

I went to Hemingway’s former residence because John’s favorite writer was Hemingway. At the same time, John is also a teacher. His illness makes him forget the names of his wife and children, but he can easily say Hemingway’s works. Hemingway’s famous The Old Man and the Sea was finished here in Xisuo Island, and it is John’s favorite work.

Two old men "ran away from home" behind their children’s backs. John couldn’t drive because of illness, but during the journey, he drove the old car at a gallop. When Ella called the children, she told them, "Son, we won’t be long. There are some things that I must finish with your father.".

The film fills in the grief and sadness that Alzheimer’s disease would have brought to the family with a lot of jokes, making the whole film easy and interesting.

During the trip, John left his wife alone and drove away. When Ella got on a passerby’s motorcycle and caught up with John, John’s reaction was, "Why are you sitting on a motorcycle?" He has completely forgotten that his wife traveled by car with him.

Similarly, when he arrived in Pennsylvania, he asked Ella, "Where are we?" After Ella told him, he asked, "What are we doing in Pennsylvania?" He will forget his children, mistake his students, and forget the purpose of this trip.

However, he can’t forget English grammar. On the way, when they were forced to hand over the money by a sudden robber, he did not forget to correct the grammatical mistakes made by the robber. At this time, Ella scared away the robbers with a prepared shotgun.

"Love Before Memory Dies" is adapted from Michael Sadrian’s novel of the same name. As a road movie, it reveals the story of travel and uncovers an old story (not much to say, it will be spoiled if you talk too much! ), and behind this past, the focus is on marriage and old age.

In the last period of life, their attitude is not negative at all, and life is full of interest everywhere. Ella, played by helen mirren, painted her nails, wore a wig and put on lipstick. Even though she is not young, she is still a delicate woman. During the journey, the two will also look at old photos with slides.

From the preview, we can also see that the two spent a beautiful and romantic night in the hotel suite. John talked to ella to the fullest; "I can’t believe my wife is so beautiful", the gentleman invited her and they embraced and danced together. The couple who have been together for fifty years have a very funny and warm daily life, and their love is indestructible in the face of aging and death.

The two leading actors won numerous awards.

"Love Before Memory Disappears" was selected as the main competition unit of Venice Film Festival in 2017. After the premiere of the film festival, some media reporters praised helen mirren’s performance. Helen mirren won the Best Actress at the Venice Film Festival in 2006 for her film, and won the Oscar for Best Actress for The Queen the following year.

Helen mirren in The Queen is noble and solemn, but very conservative. When helen mirren portrays Elizabeth II after learning of Princess Diana’s death, she reminds herself by saying "I am the queen" every day. And her superb acting skills have been greatly affirmed.

In addition, helen mirren won the Best Actress Award at Cannes Film Festival with and twice.

Donald sutherland, the actor, should be the most familiar Canadian in China. He is also quite powerful. He is the winner of the 90th Oscar Lifetime Achievement Award. Previously, he won the Golden Globe Award for Best Supporting Actor twice for Citizen X and War Path.

Donald sutherland has appeared in many films, including series,,, and so on. It is worth noting that he once appeared in the works directed by Xiaogang Feng in 2001. His role is Taylor, the great Hollywood director who came to China to make a film.

It can be said that the performances of donald sutherland and helen mirren were impeccable. Many foreign media commented on "Love Before Memory Dies", although they were quite critical of the film’s plays, they still affirmed the performance of these two drama bones, saying that this is the most attractive part of the film, which is quite convincing. "Every wrinkle is a play, and every expression contains the most complicated emotions in the character’s heart."

3 Italian local teams shoot American films.

Paolo Virzì, the director of Love Before Memory Dies, has shot many Italian local comedies, and can be said to be one of the representative figures. His "My name is Tanino" has all been shortlisted for the Venice Film Festival. "Love Before Memory Dies" is the fourth time that he has been selected for the Venice Film Festival.

But his international fame is not very great. In the 74th Venice Film Festival, many famous directors gathered, and his works also received a lot of attention. Especially with the blessing of the two leading actors, the judges can feel the more delicate emotional expression.

Paolo Virzì never thought that he would make a film that had nothing to do with Italy. When he was invited by an American film producer, he decided that helen mirren and donald sutherland must play the roles.

He said: "When I was filming this film as an American director, I always reminded myself of my Italian identity. On the set, I felt the common feelings of human beings. I tried to look at this story from an Italian perspective, and I kept my own style: shooting this film with a story that is true, human, ironic and mixed with comedy and tragedy. "

Yes, this is the concept that Paolo Virzì has always adhered to: there is always tragedy in comedy, and only dramatic plots can make people laugh.

The foreign media "SSG Syndicate" described the film as a bittersweet and warm journey, and the excellent performance made this film. Film Journal International commented that although this film is a bit ordinary, it is very enjoyable in most cases.

When talking about this film, "CineVue" said: "Sorrow and sadness are often dangerous, but" Love Before Memory Dies "is not like this. Even if love comes to an end, they are still celebrating." The critics of RogerEbert.com even shed tears when watching it.

In addition, although the film was shot in the United States, most of the film’s creative team are Italian. Photographer Luca Bigazzi has worked with Italian director paolo sorrentino in many film and television dramas.

Musician Carlo Wizz and director Paolo Virzì are old partners, and he has participated in Osodo and My Name is Tanino.

Editor Jacob Quadri worked with the director on My Name is Tanino, but he is famous for working with Italian director bernardo bertolucci.

　　The Economic Information Daily reporter learned from the 2019 World Artificial Intelligence Conference on the 29th that China’s artificial intelligence open innovation platform has added a "new army", and 10 head enterprises including Huawei’s basic software and hardware platform, Ping An inclusive finance platform and Xiaomi’s smart home platform have been officially selected.

　　As an important driving force of the new round of scientific and technological revolution and industrial transformation, the development of artificial intelligence industry once again ushered in the policy "dividend" period. In this field, China has gradually embarked on a unique development path of demand-oriented leading business model innovation, market application forcing basic theory and key technology innovation.

　　Support policies for platform expansion are intensively introduced.

　　Shanghai will speed up the construction of a new generation of national experimental zone for artificial intelligence innovation and development, promote scientific and technological innovation and institutional innovation in the same direction, make all the vitality of artificial intelligence knowledge, technology, management and capital compete with generate, encourage the latest achievements of artificial intelligence to take the lead in "testing the water" in Shanghai, strive to make original breakthroughs in some key core areas, and strive to become an important source of global artificial intelligence innovation. This is the information obtained by the reporter at the World Artificial Intelligence Conference on the 29th.

　　At the same time, Shanghai will make good use of major opportunities such as the construction of a new area of the Pilot Free Trade Zone, the integrated development of science and technology innovation board and the Yangtze River Delta, build a global frontier innovation platform and benchmark for application scenarios, promote standard communication, facility connectivity, smooth trade and financial intermediation in the field of artificial intelligence, and promote the cross-regional cross-disciplinary cross-industry development of artificial intelligence.

　　This is just a "microcosm". At the forum on the same day, the Ministry of Science and Technology officially added ten national new-generation artificial intelligence open innovation platforms, including relying on Shanghai Yitu Network Technology Co., Ltd. to build a national new-generation artificial intelligence open innovation platform for visual computing, relying on Shanghai Mingluo Artificial Intelligence (Group) Co., Ltd. to build a national new-generation artificial intelligence open innovation platform for marketing intelligence, and relying on Huawei Technologies Co., Ltd. to build a national new-generation artificial intelligence open innovation platform for basic software and hardware. Since then, China’s national AI innovation platform has expanded to 15.

　　While building a top-level communication platform for the development of artificial intelligence in the world, the Ministry of Industry and Information Technology also continued to "unveil the list" for the world. At the meeting, four test tracks were launched: intelligent networked car, medical image-assisted diagnosis, visual image identification and smart sensor.

　　New technology blessing industrialization accelerates landing

　　Under the "blessing" of new technologies, the industrialization of artificial intelligence in China has accelerated. "According to the calculation of relevant institutions, the scale of China’s artificial intelligence industry is expected to exceed 160 billion yuan by 2020, driving related industries to exceed 1 trillion yuan." Lin Nianxiu, deputy director of the National Development and Reform Commission, said at the meeting.

　　At present, the blueprint of a new generation of artificial intelligence industry in China has initially appeared. Among them, the national new-generation artificial intelligence innovation and development pilot zones in Beijing and Shanghai have taken the lead, and the new-generation artificial intelligence demonstration parks are accelerating. The three major artificial intelligence industrial clusters represented by Beijing-Tianjin-Hebei, Yangtze River Delta, Guangdong, Hong Kong and Macao have taken shape, and the total number of artificial intelligence enterprises accounts for 86% of the country.

　　With the development of new technologies such as big data, cloud computing, speech recognition, face recognition, security, somatosensory interaction, and intelligent manufacturing, in addition to BAT betting, Haier, Huawei, Xiaomi, Meituan, Didi, and Today Headlines have also entered the field of artificial intelligence.

　　In this regard, industry experts pointed out that "artificial intelligence+manufacturing" is still an important foothold for the development of artificial intelligence. With the spillover effect of artificial intelligence on traditional industries, the application scenarios of artificial intelligence enterprises will accelerate. At present, in addition to building autonomous driving by Baidu, building urban brains by Alibaba Cloud Company, building medical images by Tencent, building intelligent voice by Iflytek and building intelligent vision by Shang Tang Group, the new generation of artificial intelligence open innovation platforms are widely used in manufacturing, medical care, transportation, home, security, network security and other fields. There are more than 1,000 artificial intelligence enterprises in China, and the upsurge of AI chips and open source continues to heat up. The head start-ups such as Shang Tang, Yuncong, Defiance and Yitu are facing fierce competition.

　　Take SAIC Motor Group as an example. In recent years, it has built the largest cloud computing big data center and the first artificial intelligence laboratory in the industry around the three major areas of intelligent driving, smart travel and intelligent manufacturing, actively explored the integration of big data, cloud computing, artificial intelligence, 5G and other information and communication technologies with application scenarios, seized the development opportunity of deep integration of cutting-edge technologies and the real economy, and accelerated the evolution and transformation of the automobile industry. The 5G smart heavy truck is the latest achievement of SAIC’s independent innovation. Combined with the advanced 5G-V2X vehicle communication technology, it can realize L4 automatic driving, centimeter-level positioning, accurate parking, interaction with automation equipment and queue driving.

　　The penetration of the new generation of artificial intelligence technology into traditional industries is unprecedented. Lei Tao, CEO of Tianyun Big Data, said that with the mature application of cloud computing and open source software technology and the arrival of the era of big data, IT began to transform into DT, the ecology was reshuffled, and the information industry itself had undergone subversive changes.

　　The construction of industry legal system has been accelerated and improved.

　　As a new thing, artificial intelligence has been controversial in law and ethics. In May 2019, the Shanghai National New Generation Artificial Intelligence Innovation and Development Experimental Zone was unveiled, which clarified the relevant tasks of establishing and improving policies, regulations, ethical norms and governance systems. In June, the National Professional Committee of New Generation Artificial Intelligence Governance issued the Principles of New Generation Artificial Intelligence Governance, which highlighted the theme of responsible and open collaboration.

　　On the 29th, the Youth Working Committee of Shanghai Computer Society issued the Shanghai Declaration on Innovative Governance of Artificial Intelligence for Young Scientists in China in 2019 (hereinafter referred to as the Shanghai Declaration), emphasizing the four major responsibilities that should be followed in the development of artificial intelligence: ethical responsibility, safety responsibility, legal responsibility and social responsibility.

　　Ma Huateng, Chairman and CEO of Tencent Board of Directors, said that the urgency of AI governance is getting higher and higher, and AI governance should be guided by "technology is good" to ensure that AI is "knowable", "controllable", "available" and "reliable". Ma Huateng also said that today, no country has all the resources, technologies and capabilities needed for a new round of global scientific, technological and industrial revolution. Strengthening global governance and cooperation is an indispensable part of the development of AI.

　　"We must actively promote pluralistic co-governance, adhere to multi-agent participation, combine multiple means, tailor governance rules, deepen moral and ethical research, strengthen security, protect personal privacy, standardize industry order, and escort the healthy and orderly development of artificial intelligence." Lin Nianxiu revealed that the country will focus on three major actions in the next step.

　　The first is to implement the artificial intelligence innovation partner action. Focus on 100 artificial enterprises, intelligent technology enterprises and application enterprises, support collaborative research and development, collaborative production and collaborative promotion, solve common technologies, and promote the deep integration of artificial intelligence and real economy. The second is to implement artificial intelligence resource sharing actions. Build an artificial intelligence industry innovation center, improve the open source platform system, deepen the integration of government information systems and information resources sharing, issue guidance to promote the development of new infrastructure, and build an artificial intelligence industry ecology. The third is to implement the open development action of artificial intelligence. Deepen all-round cooperation with countries around the world in the fields of artificial intelligence technology, standards, industries, laws and regulations, ethics, etc., discuss artificial intelligence governance rules, jointly build major artificial intelligence projects, and share the development achievements of artificial intelligence.

　　The PLA Military Orchestra played the swearing-in ceremony in the Great Hall of the People. Photo by Sun Xiaomeng

　　This is the first time since the founding of the Republic that a grand constitutional oath ceremony was held at the National People’s Congress. The people of the whole country witnessed this solemn and sacred process through television cameras.

　　As part of the swearing-in ceremony of the national leaders’ constitution, the two pieces of music, the swearing-in ceremony song and the chairman’s horn, were specially created by the PLA Military Orchestra and have not been played in public before.

　　"Now hold the constitutional oath ceremony of the first meeting of the 13th National People’s Congress of the People’s Republic of China!" At 10: 50 am on March 17th, a solemn and powerful bugle sounded at the Great Hall of the People. With the music played by the Military Orchestra of China People’s Liberation Army, the swearing-in ceremony of the Constitution kicked off. The ceremonial soldiers marched forward, escorting the Constitution of People’s Republic of China (PRC) and placing it on the oath platform.

　　接着，新当选的国家主席、中央军委主席习近平从主席团座席起身走向宣誓台时，又一段铿锵激昂的号角奏响，将整个宪法宣誓仪式烘托得更加神圣与庄严。

　　创 作

　　“今年2月初，全国人大交给我们一项任务——为宪法宣誓仪式创作一首乐曲。”解放军军乐团副团长张海峰告诉记者。

　　这样的创作，看似开放自由，实则限制颇多，音乐的时长、风格、元素等都需要考虑仪式的实际情况。

　　军乐团经过研究，首先将音乐形式确定为号角。“号角，有昭示的含义。”在宪法宣誓仪式中，宣誓人庄重地诵读誓词是整个仪式最重要最核心的部分。在此之前演奏号角，昭示神圣的一刻即将来临，最为合适。

　　“第一，选用国歌作为音乐素材；第二，最后以长音收尾；第三，乐曲的配器增加长号。”代表军乐团在人民大会堂里工作了34年的张海峰根据自己的经验给创作者提出建议。

　　在这样重要的场合上，使用的音乐元素需要慎重考虑，国歌无疑非常合适——它是国家的象征，足够庄重，仪式感强。

　　乐曲以长音结尾，则蕴含微调的妙处。“举行宪法宣誓仪式时，宣誓人既可能是一位领导人，也可能是数位领导人，走到宣誓台前的脚步有快有慢。以长音收尾，便于根据实际情况对尾音做出调整。”张副团长说。

　　至于乐器的选用，“通常说来，号角用小号作为主要乐器。但增加长号后，声部可以由3个变为8个。”短短20秒的乐曲才能够表现足够丰富的内涵。

　　最终，创作了“9·3”阅兵号角、2018年元旦天安门升旗号角等作品的解放军军乐团创作室副主任郭思达完成了作曲任务。作品交回人大审定后，获得通过。军乐团又收到建议，再创作一首。

　　“新的曲子可以使用国际歌作为素材，并增加乐器小军鼓。”张海峰从党代会闭幕式上演奏的国际歌得到灵感。

　　最终，第一首曲子被选作宣誓仪式曲，第二首曲子由于打击乐的加入，节奏感强，更加激昂奋发、铿锵有力，成为主席出场号角。

　　准 备

　　解放军军乐团此次演奏宣誓仪式曲和主席出场号角时，在形式上做出了特别安排——通常只用在室外举行的国家典礼上的礼号，首次走进了人民大会堂。八面号旗挂在微微上扬的号管上，给人以耳目一新的感觉，仪式感更强，烘托典礼的隆重。

　　In order to ensure that there are no mistakes in the performance at the constitutional oath ceremony, "I went to the General Assembly Hall to rehearse for five times." As the conductor of live performance at the venue, Zhang Haifeng said.

　　However, the first rehearsal found problems. Generally, when a band plays, a certain distance will be left between the conductor and the musician, so that the musician can observe the conductor’s movements. However, limited by the space in the Great Hall of the People, there is only one row of seats between the conductor and the first row of musicians, and the stations are almost parallel. In the past, the band could make trombone players stand back by adjusting their formation. But this time, there are only eight trumpeters, eight trombones and two military drummers. In this way, the distance between the trombone player and the conductor is too close, and the line of sight is just blocked by the horn of the trombone, and the conductor’s action is completely invisible.

　　In order to solve this problem, the military orchestra asked the musical instrument support personnel who should have been sitting in the back row to leave to make room, and the musicians moved back two rows as a whole.

　　Play

　　Eighteen performers of the PLA Military Orchestra have been carefully selected from the orchestra and participated in many important performance activities. They are of excellent quality and confident in their performances.

　　However, because of the many "firsts" of activities, there is no experience to refer to, and I am still nervous. "The procedures for swearing-in activities need to be remembered in particular." For example, before president and the chairman of the Central Military Commission take the oath, the host of the conference will first announce the ceremony, and then broadcast it once by the live broadcast host of the conference. At this time, the performance will start; Before the vice chairman and members of the Central Military Commission take the oath collectively, the host of the live broadcast will increase the password of "Please take the oath in place".

　　Before the performance, although Zhang Haifeng had memorized the procedure, his heart was still tense. The same is true for musicians. "At that time, some trumpeters were already inhaling and ready to play, but I couldn’t beat until the password was finished." Zhang Haifeng said, "All the comrades in the regiment are sweating for me."

　　At the end of the performance, Zhang Haifeng felt proud and lucky. Proud, he participated in such groundbreaking activities on such a solemn and sacred occasion as a live conductor on behalf of the military orchestra. Fortunately, he caught up with the new era. Since the 18th National Congress of the Communist Party of China, the frequency of military orchestras participating in major foreign affairs activities has become higher and higher, which has made him personally feel that the international status of the motherland is constantly improving and the country’s development is getting better and better.

　　Tips and representative works

　　The Military Orchestra of China People’s Liberation Army belongs to the Political Work Department of the Central Military Commission. Formerly known as the North China Military Region Military Band established in January 1948. In 1949, he participated in the founding ceremony in New China as the main band and played National Anthem of the People’s Republic of China for the first time. It was formally expanded and established in 1952.

　　Over the years, the Military Orchestra has composed and performed more than 2,000 wind music works in different forms, and recorded and distributed hundreds of wind music tapes, records, music scores and monographs. Representative works include: Welcome March (Wei Qun), Farewell March (Zheng Lu), Flowers Song (Yan Xiao ‘ou), Athletes March (Jia Shuang), Horn of Handover Ceremony of Hong Kong and Macao (Wang Hesheng), Divided March (Luo Lang) and so on.

　　CCTV News:In the early morning of the 22nd, a flight independently developed by China for bio-aviation kerosene was added and landed smoothly in Chicago, USA. Surprisingly,The bio-jet fuel filled in this flight is made of waste cooking oil, which is what we call waste cooking oil!

　　The first transoceanic commercial passenger flight of bio-jet fuel in China

　　This is the first trans-ocean commercial passenger flight of bio-jet fuel in China.

　　Hainan Airlines 787, fueled with China Petrochemical No.1 bio-jet fuel, took off from the Capital Airport at 14:15 Beijing time on the 21st. Carrying 186 passengers and 15 crew members, it landed smoothly at Chicago O ‘Hare International Airport at 2:11 am Beijing time on the 22nd after 11 hours and 41 minutes.

　　Captain Sun Jianfeng:

　　The whole flight was very smooth and smooth. The maximum flying altitude has reached 41,000 feet. The engine is in good condition. Fuel is in good condition. The purpose of this verification flight was completely achieved.

　　canEffectively reduce carbon emissions

　　Bioaviation kerosene takes renewable resources as raw materials, mainly includingCoconut oil and palm oilEtc., even includingAnimal fat, waste fat on the table, which is what we often call "gutter oil".

　　Sinopec No.1 Bio-jet fuel used for transoceanic commercial passenger flights is made from waste cooking oil and blended with conventional jet fuel at a ratio of 15:85.

　　The use of bio-jet fuel can effectively reduce carbon emissions while ensuring the original flight safety and efficiency.

　　Large-scale emission reduction: equivalent to planting 300 million trees a year

　　Statistics show that 1 ton of traditional jet fuel will emit 3.2 tons of carbon dioxide after burning. At present, China’s jet fuel consumption is about 30 million tons. If all of them are replaced by bio-jet fuel, at least 30% of each ton of bio-jet fuel will be reduced, which will reduce carbon dioxide emissions by about 33 million tons a year, which is equivalent to planting nearly 300 million trees and stopping nearly 20 million economical cars for one year.

　　Ji Yuan, deputy director of the Development Planning Department of the Civil Aviation Administration, said that bio-fuel is a very effective means for civil aviation to achieve the goal of emission reduction while expanding production.

　　"Waste oil" breaks through the bottleneck of aviation industry development

　　At the 2014 United Nations Climate Summit, China promised to reduce carbon emissions by 40%-45% by 2020, in which the civil aviation industry is a key target.

　　Ji Yuan, Deputy Director of Development Planning Department of CAAC:

　　The current goal of ICAO is carbon neutral growth after 2020. That is, after 2020, although production is still increasing, carbon emissions will no longer increase. Therefore, whichever country develops rapidly, the pressure on which country is bound to be great.

　　The carbon dioxide emitted by biofuels can be absorbed by plants, and the carbon dioxide emission can be reduced by more than 35% or even more than 50% by this cycle. At the same time, it can also reduce the possibility of waste oil flowing to the table.

　　Only four countries in the world have it.This technology

　　China began to develop bio-jet fuel in 2006, and now it has become the second largest country after the United States, France and Finland.The fourth country with independent research and development technology of bio-jet fuel.

　　In 2011, Zhenhai Refining & Chemical Company of China Petrochemical Company built the first demonstration device of bio-jet fuel industry in Asia in its production base, with an annual production capacity of 100,000 tons, which is enough for Beijing to fly to new york for 200-300 times.
