在诸多不利的环境因素中,对飞行人员特别是军用飞机飞行人员威胁最大、影响最为明显的是急性低压缺氧。在现代航空中,虽然已经有密封座舱及性能良好的供氧装备,但由于飞机密封增压座舱失密封、面具佩戴不严或供氧系统故障等,均可引起飞行人员不同程度的缺氧。缺氧对人体的生理影响已有过大量研究,但对脑功能影响的研究方法各异,结果 Among many unfavorable environmental factors, the most serious threat to pilots, especially military aircraft pilots, is acute hypobaric hypoxia. In modern aviation, although there are already sealed cockpits and well-equipped oxygen supply equipment, flight personnel may experience varying degrees of hypoxia due to the lack of sealing of the cockpit, mask wear or oxygen system failure. Physiological effects of hypoxia on the human body have been a large number of studies, but different ways of studying the impact of brain function, the results
