我国卫星生物搭载试验

China's Biomedical Experiment on Recoverable Satellites

我国1990年10月在返回式科学卫星上成功进行了首次高等动物的空间飞行试验。除对高等动物小白鼠做了生存试验外,还研究了航天特殊环境对果蝇繁殖发育、蚕卵胚胎发育和小麦种籽的影响。这次试验获得了满意的结果,它对今后的空间生命科学研究是十分有价值的。

A biomedical experimental system, developed by the Insti-tute of Space Medico-Engi-neering, was tested on the recoverable satellite in October 1990. This system composed of five subsystems: a cabin with function of temperature control; atmosphere pressure control subsystem; air purification and humidity maintaining subs-ystem; animal service subsystem with functions of waste collec-tion, food and water supply; measurement, control and pow-er management subsystem. Be-sides two white mice, biomedical researches on the genetics of fruit flies and the development of silkworm eggs and wheat seeds were also conducted dur-ing the space flight. The experi-ments were fruitful: the engi-neering systems worked well during flight, the results of test animals and other biomedical studies were exciting. The expe-riences of the present space biomedical experiments are very valuable for the microgravity re-searches in the future.
