摘　　要：本文讨论了载人航天器采用常压低氧 ( 1atm氧浓度低于 2 1 % )和低压低氧 (舱压低于 1 .0atm ,氧浓度 2 1 % )座舱环境的利与弊。认为 ,适度的低氧 ( 0 .8～ 0 .9atm ,2 1 %O2 ) ,无论对短期航天或长期航天都是有益的。对于长期航天 ,舱内微小气候的控制模式是值得重新考虑的 ,持续地控制在狭小的舒适带不利于保持人对环境变化的适应能力。探讨这一问题具有理论意义和实用价值。The favourable and the unfavourable factors of normal baric hypoxia (1.0 atm,oxygen concentration below 21%) and hypobartic hypoxia (cabin pressure below 1.0 atm,21% O 2) in the cabin for manned space flight were discussed.Author considered that proper hypobaric hypoxia in the cabin (0.8～0.9 atm,21% O 2) would be benifit no matter for long or short term space flight.For long term space flight,the microclimate control model in the cabin should be considered again,it controlled in a narrow comfortable zone would unfavourable to human adaptability to changing environment.All these problems proposed in this paper need to be further studied.
