利用我国返回式科学实验卫星，搭载装有２只小白鼠的生物舱，在近地球轨道上飞行８ｄ，初步观察飞行因素对小白鼠的影响。实验前对动物进行选训，挑选出体格健壮、对环境适应能力强的２只昆明种、雄性、成年小白鼠进行飞行。飞行前，对舱内仪器、设备和动物均进行消毒检疫处理。小白鼠在轨道上存活了５．４ｄ，由於失重原因，飞行后小鼠的骨形成率有降低趋势，力学特性无明显变化；小鼠脑、肺等组织残留了动物死亡前发生的血管性变化和细胞坏变。并对飞行小鼠的死因进行了分析，为我国的航天生物医学研究积累了科学资料与经验。
Using the return type scientific experiment satellite of our country, carrying a biological tank equipped with two white mice and flying in near-Earth orbit for 8 days, the effects of flying factors on the mice were initially observed. Before the experiment, the animals were selected for training, and two Kunming species, male and adult mice with strong physique and strong adaptability to the environment were selected for flight. Before flight, disinfect and quarantine all the equipment, equipment and animals in the cabin. The mice survived on orbit for 5.4 days. Due to the reasons of weight loss, the bone formation rate of mice in flight decreased and there was no significant change in the mechanical properties. The brain, lung and other tissues remained the vascular changes before the animals died And cell degeneration. And the cause of death of the flying mice were analyzed, which accumulated scientific information and experience for China’s space biomedical research.
