摘　　要：通过模拟分子筛制氧系统供气范围，即减压前富氧气体的高空迅速减压实验，观察对机体的生理影响和氧反向弥散的变化。实验结果表明，当供氧浓度低于６０％，在缺氧暴露１０ｓ内出现缺氧反应；而高于７０％，在迅速减压后６～８ｓ之内的生理反应是等效的。高空迅速减压后氧的的反向弥散有两个过程，且与减压瞬间生理效应和有效意识时间有联系。The effects on physiology and oxygen inversive diffusion following the rapid decompression at high altitudes,with various oxygen-rich supplies before decompression simulating the range of gas from the molecular sieve oxygen generating system(MSOGS)were observed. The results demonstrated that while the oxygen content was lower than 60%, the hypoxia sign appeared within 10s after hypoxia expose. There was a physiological equivalent range in 6～8s after decompression when it was beyond 70%. The oxygen inversion diffusion after decompression had two processes, which was associated with the time of useful consciousness and physiological effects.
