title: [Possibility of adopting hypoxic environment in the cabin for manned space flight].
abstract: 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% O2) in the cabin for manned space flight were discussed. Author considered that proper hypobaric hypoxia in the cabin (0.8-0.9 atm, 21% O2) 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.
