摘要
由于昆虫和种子的呼吸代谢率很小，氧耗量少，所以在卫星搭载的小型生物舱内，用聚丙烯膜囊封裹超氧化钾以隔绝水汽，但二氧化碳能透入与之直接反应产氧，另用氢氧化俚吸收掉部分二氧化碳，以自动平衡氧分压的供氧方法，可保证密闭舱内的氧分压波动在±１０％以内．实验证明，新的化学产氧方法是有效的，空间飞行实验也已确认这种生命保障体系对生命活动无不良影响．
The metabelism of insects al1d the seeds are low and the oxygen consumptions are Small;Therefore a new methed was developed for life support system inside the small biocab-in on board satellite.Potassium superoxide was wrapped in a polypropylene membrane.Car-bon dioxide can penetrate this membrane and revivify the potanssium superoxide directly to regenerate oxygen.Part of the carben dioxide was absorbed by lithium hydroxide to balance the oxygen partial pressure.So that its fluctuation can be maintain within±10%.Experi-ment on beard biosatellite proved that the system works well for seeds and insects.
