Many people once said that Chinese people are eager for great achievements and Chinese scientists are impetuous. With a little scientific research innovation, they would boast to the outside world, claiming to be the best in the world or the world's first. In fact, there is a big gap with foreign countries, the innovative achievements are exaggerated, many of which cannot be industrialized, and after releasing the good news through the media, they soon fizzle out. Regarding this statement, based on Baidu searches, it is not difficult to find that between 2016 and 2017, Chinese official media publicized "world's first" technologies. Further verification was conducted through CNKI (China National Knowledge Infrastructure) and relevant patent searches, and some research was carried out on the application and achievements of some current project technologies. We found 5 cases, which will now be compared one by one. "Intelligent micro-casting and forging" 3D printing technology In July 2016, domestic media reported on a metal 3D printing technology "intelligent micro-casting and forging" developed under the leadership of Professor Zhang Haiou from the School of Mechanical Engineering, Huazhong University of Science and Technology. Since this technology uses 3D printing combined with forging, it directly avoids 8 processes in the traditional casting and forging process from casting, blooming to finishing. It not only has higher production efficiency and significantly reduces costs, but also the manufactured metal components have higher strength, toughness, fatigue life and reliability. The size of the produced products can be 4 times that of similar German enterprises, so it is the world's first. After this news was released, it caused a huge sensation in China. According to the description of this technology, if it is used in the production of engines, it may play a significant role in improving the quality of motor vehicle engines and aircraft engines, and is also of great value for the production of key components of some large industrial products, with extremely important significance for enhancing Made in China. So what is the current situation of this technology? In fact, this technology has achieved commercial application. Because Professor Zhang Haiou holds the patent for this technology, Sinosteel Group invested to establish Wuhan Tianyu Intelligent Manufacturing Co., Ltd. with him, which specializes in undertaking the customization of large high-precision metal forgings through 3D printing, mainly providing comprehensive solutions for high-end forgings for industries such as aerospace, navigation, nuclear energy, petrochemicals, metallurgy, transportation and military weapons. With a number of patented technologies, the company has produced a series of manufacturing equipment, specializing in the production of ship propellers, aircraft engine casings, and can also provide high-precision medical 3D printing, and even aircraft landing gear. At present, it has 8 patented technologies and 14 software copyrights. Quantum Science Experiment Satellite "Micius" At 1:40 on August 16, 2016, the Long March 2D carrier rocket successfully sent the world's first quantum experiment satellite "Micius" into space, which will enable China to realize quantum communication between satellite and ground for the first time in the world. Recently, the University of Science and Technology of China used the "Micius" scientific experiment satellite to achieve the first 1200-kilometer landmark quantum state teleportation, making important experimental progress in the field of long-distance quantum state teleportation. This experiment realized for the first time quantum state teleportation between two ground stations 1200 kilometers apart on Earth, marking an important step for humans in building a global quantum information processing and quantum communication network. The Micius quantum science experiment satellite is the world's first quantum science experiment satellite, with a mass of 631 kilograms and a designed service life of 2 years. The quantum satellite project is one of the pilot projects of the space science program of the Chinese Academy of Sciences, and the engineering project is undertaken by the National Space Science Center of the Chinese Academy of Sciences. The emergence of quantum satellites is inevitable because humans will enter the quantum era in the future. At present, the United States has developed the world's first quantum computer and become the first country to enter the quantum era. Experts once said that it is almost impossible for large Internet companies like Alibaba and Tencent to overcome servers or use hacking techniques to steal passwords of online payment software, but with quantum technology, all existing encrypted information can be easily cracked. Quantum technology is a technology of spear and shield. While quantum technology causes significant harm to existing encryption devices, quantum encryption technology can ensure that all information will not be compromised by hacking techniques, so it is very important in the field of encrypted transmission. World's largest single-aperture radio telescope "Sky Eye" On September 25, 2016, the 500-meter aperture spherical radio telescope, referred to as FAST and also known as "Sky Eye", was officially put into use in the karst sinkhole in Guizhou. FAST will maintain its position as a world-class facility in the next 10 to 20 years and become a "powerful tool" for astronomical research in China and the world. On March 25, 2011, Xi'an University of Electronic Science and Technology, Tsinghua University and Harbin Institute of Technology, under the auspices of chief engineer Nan Rendong, built a 500-meter aperture spherical radio telescope in Pingtang County, Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province, commonly known as "China's Sky Eye". The total investment is 667 million yuan, equivalent to the size of 30 football fields, with a total reflection area of 260,000 square meters. The device has achieved one achievement after another, shaking the international astronomical community. Many international institutions have cooperated with "China's Sky Eye" and praised China's scientific and technological strength, saying that it is becoming increasingly strong and gradually leading the world's astronomy forward! Recently, there has been a continuous stream of good news. Chinese research teams have observed and calculated the origin evidence of fast radio bursts through China's Sky Eye, and the academic results were published in the international authoritative academic journal "Science", attracting the attention of international peers! It is reported that the radio burst is billions of light-years away from the Earth, and the energy consumed in a few milliseconds is equivalent to the energy released by the sun in a year. The research topic may have a revolutionary impact on the international astronomical and physics circles. The fleeting flash of a few millimeters captured by China's Sky Eye has traveled through interstellar space for billions of years before finally reaching the Earth. No wonder foreign media said: God favors "China's Sky Eye". The difficulty of capturing this signal is extremely high, which benefits from the extremely strong detection capability of China's Sky Eye. Aiguang Vision "bionic eye" In 2017, media reported that the Shanghai Institute of Microbiology and Information Technology of the Chinese Academy of Sciences invented the "bionic eye", which is the world's first. The inventor is researcher Zhang Xiaolin, who is also the founder of Aiguang Vision. This technology uses machines to simulate the structure of the human eye and brain, obtains stereoscopic images by adjusting the position left and right, can track the movement of an object, and can also switch objects at will, allowing users to see wherever they want. This technology has been installed on Siasun dual-arm robots for grabbing items on industrial assembly lines, and can also be applied to fields such as unmanned driving, UAV navigation, VR, AR and sports event tracking. In 2016, it was used on Shanghai Metro Line 11 to specially monitor the dynamic geometric parameters of the catenary in real-time for rail transit, and determine the 3D coordinates, attitude, structural integrity and visible light arcing of the pantograph and catenary. This technology has now been commercialized and was recently used on Shanghai Metro Line 18 trains. 3D bioprinted blood vessels At the end of 2016, Xinhua News Agency released a news that Professor Kang Yujian, a famous Chinese expert, officially announced in Chengdu that the world's first in vivo experiment of 3D bioprinted blood vessels in animals was successful, achieving a major breakthrough in stem cell application technology. Professor Kang used adipose mesenchymal stem cells from rhesus monkeys to prepare 3D bioprinting ink, then used his self-developed 3D printing equipment to print a section of aorta, and replaced a section of artery in the rhesus monkey. After that, no abnormalities were found in the physiological indicators of the rhesus monkey. The successful development of this technology may solve the problem of endothelialization of artificial blood vessels, bringing hope to 1.8 billion cardiovascular disease patients. After the successful development of this technology, Languang Innolight, a subsidiary of listed company Languang Development, was responsible for promoting the project. Therefore, in its 2016 annual report, Languang Development stated that it would apply to relevant regulatory authorities for clinical trials. In its 2017 annual report, it stated that it had initiated the FDA clinical trial application for the project. The 2018 annual report stated that according to the review opinions, the FDA clinical trial application for the project was supplementing relevant research data such as pharmacy and pharmacology and toxicology. By 2021, Languang Development still stated the same to the outside world. In February this year, news from Languang Development showed that the clinical research project of 3D bioprinted blood vessels had just obtained the record approval from the National Health Commission, and it is expected to start in the second quarter of this year. In other words, this technology was successfully tested 5 years ago, but clinical research has not yet been carried out. Summary It can be proudly said that in the past 5 years, China's scientific and technological progress has been far greater than many people's imagination, especially in artificial intelligence, quantum technology, 5G, biotechnology, green energy and other aspects. A report from Harvard University in the United States shows that China may become a global leader in these aspects, and in some aspects has already ranked first in the world. Behind this is inseparable from the hard research and development of Chinese scientific and technological personnel, especially China's innovative and breakthrough system design for the ownership of scientific and technological achievements. In many places in China, the proportion of scientific and technological achievements transformation income distributed to researchers has been increased to more than 70%, and in some places even 90% or 100%. It can be said that in recent years, this has greatly mobilized the enthusiasm of Chinese scientific researchers for innovation and entrepreneurship.
