Years after the super satellite - space platforms


Thus greatly improving the productivity of useful substances present. China, Japan, Germany, Soviet Union, Britain,[link widoczny dla zalogowanych], the United States, Canada, the Netherlands, France and many other countries are. Zhou Yongchun 1l 'Ru active in the large-scale culture of cells. Cell culture around the world have been lO0 variety of plant species, cultured cells obtained from these useful substances, after more than 300 have been identified, including alkaloids, pesticides, pigments, organic acids, anticancer drugs, Xi Faso, spices and dozens of categories, of which a large proportion of drugs in 1985, a Japanese company the first large-scale use of plant cell culture technology. Production of shikonin, and the market price of $ 4500 per kg this is the first commercialization of the technology products in Japan has hit a \production. This production method is very unique to this plant was called \Because the production of useful substances out of cells. Products of this technology is currently not much, but rapid development in the 21st century will be the formation of large industry. Recently, biologist at the University of Texas can be a successful one kind of cell culture in vitro of cotton into cotton fiber technology, now patented as cultured cells can grow to twenty areas, thus creating two smooth side, which prevent the ball from the time of the phenomenon of textiles and, since it is produced under sterile conditions, it can be sterile fiber, by changing the training methods, special purpose products made by changing the training methods,[link widoczny dla zalogowanych], you can produce on demand a certain length and thin, and the special nature of the fiber products. This technology shows commercial potential has caused law. State Songleikesi textile companies and the United States are Yu Shan Company, Dow Chemical Company, of great interest. Using cell culture technology to produce large-scale cotton production cycle can be shortened than the production of cultivated fields and ~ times, and the rejection rate of interest the product can be close to 100. It can be imagined, to the 2l century, this not only without land, without pesticides and chemical fertilizers are also industrial production of cotton fiber technology, will replace, at least in part, to replace the field followed the cultivation technology for thousands of years (the Central People's Broadcasting Station, \Feed and social program) ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... * too short, I can not meet the needs of astronomy strong concept, and 'platform' is almost immortal. For these reasons, most of America's future astronomical observation will use the space platform tasks to complete. The Soviet Union is also prepared in the air in the 2l century cyberspace to establish a variety of covering the entire electromagnetic spectrum with the space telescope's huge observatory platform for communication, communication satellites can exist grams pupil cost of the current high odd short life, the capacity is small, crowded and a lot of track weaknesses. As can be mounted in the communications platform contains a variety of large antennas and large equipment of each band, it can make the ground receiving and transmitting equipment, greatly simplified, so the 21st century, human beings can achieve a wide range intercontinental communications and personal mobile communications. The results show that compared with other spacecraft, space micro-gravity platform, the highest level, first of all Han l0 gravity of the competent application of scientific research and dichotoma. As outside air cyberspace platform is able to repeat the flight path of space to accept looking indigo unmanned spacecraft service, so gravity works in the Han application efficiency is the highest. This mainly refers to scientific research and space http materials processing and production, life and biological science research, production, etc. Jing biological system. Since 1960, the United States launched its first ground of the world view of the satellite I collapse after the anti-Earth from space observations to the board of the world's most active applications and benefits of the larger satellites one of the areas, now mainly used in the Sun, Earth environmental monitoring, atmospheric and meteorological observations, terrestrial observations, ocean view I collapse, so as to improve people's living environment Fan, crop growth status and faster development of land resources and marine resources. But modern Earth observation satellites can afford less effective loading capacity and can only be limited to a single application domain, it is difficult to complete large-scale collapse of comprehensive sets of now I tasks, In addition, the general is someone to deliver Earth observation instruments, and . Satellite life already short,[link widoczny dla zalogowanych], if an accident during operation and then fails, will the wall into a huge loss. Space platform in the century, Earth Observation with no such worries, its life is very long, but also large-capacity high-speed processing equipment assembly, so that a large number of observations in situ treatment or space platforms made pigsty ground after compression. In short, the spatial platform is full of modern satellite technology and development, following the most, is more complex than ordinary satellite, a space clamor more advanced, extremely versatile. Tough the next century, it will gradually replace all kinds of application satellites. (Central People's Radio,[link widoczny dla zalogowanych], \ More articles related to topics：
