CCTV News:From 8: 00 am yesterday (5th), the aircraft wake reclassification experiment was started in Guangzhou and Shenzhen. The wake generated in the air when an airplane flies is like the waves and eddies caused by a ship sailing in the water, so two airplanes must keep a safe distance in the air.

　　In order to prevent dangerous situations such as pitching, rolling and stall caused by the aircraft behind entering the vortex field at the front tail, ICAO has formulated wake interval standards based on practical experience.

　　The scheme of this experiment comprehensively studies the remarkable characteristics of domestic large-scale hub airports, such as aircraft types and distribution periods, and subdivides heavy and medium-sized aircraft.

　　From 8: 00 a.m., the aircraft participating in the test in Guangzhou and Shenzhen control areas began to fly according to the new safety interval standard. At 8: 05, the interval between Boeing 757 and Airbus A320 was reduced from 9.3 km to 6 km.

　　Kang Nan, Vice Minister of Air Traffic Control Department of Air Traffic Control Bureau of Civil Aviation Administration:With reference to relevant foreign standards and operating experience, and in combination with the actual operating characteristics and distribution characteristics of China civil aviation, we have studied and formulated the wake interval standard of China.

　　Taking Airbus A380, a super heavy aircraft, and Boeing 777, as examples, the wake interval between the front and rear aircraft was reduced from 11.1km to 9.3km, with an optimization range of 16.2%. However, the distance between light aircraft, medium-sized aircraft and heavy aircraft increased by 4.3km and 5.1km respectively, with an increase of more than 45%, and the possibility of being affected by the wake of the preceding aircraft was further reduced.

　　The experiment of aircraft wake reclassification will be conducted at Guangzhou Baiyun Airport and Shenzhen Baoan Airport and their control areas for one year. The first stage is the testing stage, in which China Southern Airlines, Hainan Airlines, Shenzhen Airlines, FedEx and United Parcel Service Company are arranged to participate. The second stage is the promotion stage. On the basis of summarizing the operation experience in the first stage, the wake reclassification method and separation standard are applied to all applicable aircraft operating in Guangzhou and Shenzhen airports.

　　It is estimated that the experiment of aircraft wake reclassification will improve the runway capacity and operational efficiency of civil aviation.

　　The runway capacity is expected to increase by 5% during peak hours, which can effectively alleviate the situation of route congestion, and passengers’ travel efficiency and experience will be further improved.

　　Since 2010, the average annual growth rate of China’s civil aviation flight volume is 11.6%, but the average annual growth rate of civil aviation fixed routes is only 1.7%. At present, there are usually about 400 flights a day on busy international routes, while there are 13 routes with more than 500 flights a day in China.

　　Kang Nan, Vice Minister of Air Traffic Control Department of Air Traffic Control Bureau of Civil Aviation Administration:The current ICAO wake separation standard was formed in the 1970s of last century, which limited the improvement of the capacity and efficiency of our large busy airports to some extent, and also caused unnecessary flight delays and waiting.

　　According to the calculation of the air traffic control department, the annual runway capacity of the top 10 busiest airports in China is expected to increase by about 47,450 flights, the annual runway capacity of Beijing Capital Airport is expected to increase by about 7,665 flights, and the annual runway capacity of the two airports in Shanghai is expected to increase by about 9,490 flights.

　　Beijing, June 15 (Reporter Shangguan Yun) "Has the craze for science fiction literature come?" In fact, I am not so optimistic. " Recently, Chen Qiufan, a science fiction writer, put forward the above views when interviewed by a reporter from Zhongxin.com (WeChat WeChat official account: cns2012).

　　Not long ago, his short story "Fear Machine" was shortlisted for the 10th Global Chinese Science Fiction Xingyun Award, along with works by writers such as Liu Cixin and Liang Qingsan.

　　Love reading science fiction has been rejected.

　　Like science fiction, Chen Qiufan has been interested since he was a child.

　　"I read science fiction when I was in kindergarten, but I can only read simple plots, and some contents are not very understandable." He remembers reading a series of classic works by Verne and Wells, which "felt like entering a particularly magical world".

　　When he was in junior high school, he tried to write some science fiction novels and then contributed them everywhere. At the age of 15, he sent the novel Bait to the competition and won the prize successfully. When the certificate was sent to the school, it was handed over by the class teacher. Chen Qiufan still remembers the students’ surprise at that time.

　　However, his writing career didn’t start there: after winning the prize, another novel was rejected, which made Chen Qiufan feel somewhat depressed. In addition, to prepare for the college entrance examination, in about two years, he pressed the "pause button" of writing.

　　"I tried to pick up my writing after I was admitted to Peking University. At that time, I took the path of pure literature. " But write to write, those articles can’t satisfy Chen Qiufan, "always feel not attractive enough. So I changed it to writing science fiction. "

　　Since then, he has published sci-fi works such as Fish in Lijiang and Year of the Rat, and won the Global Chinese Science Fiction Nebula for nine times. The Ghost Trio has also been included in the sci-fi anthology "Future People Don’t Exist".

　　It is not easy to add "hard science fiction" elements to novels.

　　Talking about his own creation, Chen Qiufan thinks that the more difficult thing is the combination with scientific and technological elements, that is, the "hard science fiction" elements that people often say.

　　"Not as long as ‘ Have a brain hole ’ You will be able to write good science fiction. " Chen Qiufan explained that when writing, science fiction writers also need to know the most advanced science and technology and scientific facts, and the novels will look better.

　　He feels that if there is an opportunity, science fiction writers can communicate with scientists who work in the front line. "Scientists know the most cutting-edge technology, and writers have a big brain hole. If the two are combined, there may be good results."

　　However, sometimes, some misunderstandings will make Chen Qiufan feel a little helpless. He said that some readers will confuse science fiction with popular science works to varying degrees. "The latter should be particularly accurate about all kinds of knowledge and not allow fiction; The former is still full of literary color, and the two are not the same. "

　　"The fields involved in science fiction literature are not narrow, not just aerospace, space and so on." Chen Qiufan said that it also includes anthropology, ethics and other disciplines. "For example, in The Wandering Earth, when people discuss whether it is feasible to put an engine on the earth, they also think about ecological environment protection and human ethics.".

　　Science fiction literature craze has come? may not

　　After writing science fiction for many years, Chen Qiufan has a deep understanding of the "minority" situation of this literary type: the number of writers is relatively small, and the audience is also small.

　　However, with Liu Cixin winning the Hugo Award in 2015 and the sci-fi movie The Wandering Earth showing in early 2019, this situation seems to be slowly changing. Especially after the The Wandering Earth fire, many people think that "science fiction literature fever" has come.

　　"It seems that science fiction has become a slogan, capital, IP… … A lot of people poured in at once. The film has a relatively wide audience, and The Wandering Earth’s popularity has indeed opened up a more popular market. " Chen Qiufan does not deny that people’s attention to science fiction literature has increased, but he thinks this is not enough to be blindly optimistic.

　　He gave a good reason: "The well-known sci-fi writers such as Hao Jingfang and Liu Cixin won the grand prize, and more people don’t know much about writers like me and Han Song;" There are still few publishing channels for young writers’ works in the traditional sense, and it is difficult to get ahead. "

　　"For example, Mo Yan’s teacher won Nobel Prize in Literature, and his novels are very popular, but the sales of other pure literature writers are good? No. " Chen Qiufan said that at present, the situation of science fiction literature is similar, and the publishing market only prefers great writers who can guarantee a certain sales volume, "said ‘ Science fiction literature craze ’ Come, in fact, not necessarily. "

　　Spring is full in February, and flowers are blooming. A few days ago, 10,000 mu of cherry blossoms in Xiaozhai Town, Ludian, Yunnan Province, were in full bloom, clusters and clusters, covered with branches, just like white snow, which reflected each other with Qingshan village, fresh and pleasant, and made it a quiet and peaceful beautiful countryside scene.

From 2012 to 2021, the share of local skin care increased first and then decreased, and the share of local makeup increased by nearly 14pcts； in ten years; At present, the channel and media dividends have faded, local high-quality leading brands have increased investment in research and development, product strength has increased, and high-end has quietly advanced; At the same time, local brands have a deeper understanding of domestic channels and marketing, and local brands have diverted to international high-end brands, and their overall share has entered the bottom area, and their future promotion is expected.

▍ China skin care market: the share of local brands rises first and then falls; At present, the local leading brands are diverging from international high-end brands, and their share is at the bottom.

2012-2021: The share of local skin care increased from 24.8% in 2012 to 34.3% in 2018, and then fell back to 27.7% in 2021; The share of French brands has increased from stable (14% ~ 15% in 2012-2018) to 22.1% in 2021, which is closely related to the strong product strength of French brands and their advantages in sensitive repair and anti-aging. Korean brand share rose first and then stabilized, from 1.2% to 4.5% in 2012-2016, then the mass line weakened but the high-end line increased, and the overall share was stable. Since 2022, many factors such as marketing, channels and local epidemic have caused many changes in the trend. Among them, the local leading companies are becoming increasingly high-end, and the diversion of overseas high-end brands is expected to drive the local share to the bottom.

▍ China makeup market: the share of local brands has been promoted to the leading position, and the high-end has been quietly promoted.

2012-2021: The share of local cosmetics increased from 15.0% to 28.8%, and increased by nearly 14pcts； in 10 years; The share of American makeup decreased from 33.8% to 16.2%, a decrease of 17.6pcts；; After 2016, the share of French make-up increased to 30%+,which is closely related to its advantages in brand heritage, fashion leading and product strength. The share of Korean makeup increased from 7.0% in 2012 to 11.7% in 2016, and then decreased to 8.3% in 2021. Local make-up brands have changed significantly since 2021H2: 1) From fashionable color products (lipstick, eye shadow, etc.) to technical foundation (liquid foundation, etc.), from flow play to brand building; 2) Increase R&D investment, rely on cultural confidence, and strive to catch up with international brands in some sub-categories and product series.

▍ The channel and media dividends faded, and local brands increased investment in R&D, returned to product strength and accumulated brand strength.

Channel change: from 2001 to 2010, CS stores, supermarkets and other brands gave birth to beauty channels; In 2011-2015, the offline was good, the online rose, and the brand enjoyed a double-line bonus; In 2016-2021H, international brands increased rapidly, and new brands emerged; Since 2021H, channel and media dividends have subsided.

Marketing change: from celebrity endorsement to multidimensional grass planting, from big-screen advertising to content marketing and value recognition.

Advanced R&D: In recent years, the brand of skin care of pharmaceutical origin has performed outstandingly, from "medicine" to "makeup", with better quality control and efficacy; Local brands such as Polaiya/Betani/Huaxi /PMPM gather head R&D talents at home and abroad; Synthetic biotechnology promotes the innovation iteration of beauty raw materials, local raw material enterprises flourish, and the curtain of domestic substitution of raw materials opens.

▍ Risk factors:

Discount promotion of international brands suppresses local brands; The relationship between beauty brands and e-commerce platforms is unbalanced; It takes time to accumulate significant results in R&D investment; Scattered epidemic situation repeatedly affects the demand and sales of beauty; Policy supervision strictly affects the growth rate of the industry; The speed and range of domestic substitution of raw materials may not meet expectations.

▍ Investment suggestion:

As a typical optional consumer product, beauty cosmetics have both efficacy and spiritual attributes, with efficacy depending on technology and spirit relying on culture. Local brands increase investment in R&D, and product strength is quietly improved; At the same time, we have a deeper understanding of local channels and marketing. It is expected that the share of high-end and ultra-high-end will increase in the future, which will drive the overall share to rebound. At the present stage of fading dividends and full competition, strong marketing, channels, operational capabilities and sustained high R&D investment are indispensable.
