用一年的时间随青藏铁路列车采集了2 882样本数据，随机抽取其中的1 693份，利用非参数检验及 相关分析的方法从统计学上对可能影响耐缺氧反应的因素做分析，最后发现以前到高原时缺氧反应严重程 度、性别、吸烟习惯、肥胖度、年龄５个因素对个体的抗缺氧能力有着不可忽视的影响。该结论不仅可以为减 少旅客高原反应提供指导性意见，为高原旅客列车供氧系统设计和改进提供重要依据，也可以为后续的医学 研究提供统计学基础。

2 882 samples were taken in Qinghai- Tibet railway cars, and 1 693 samples were taken out randomly, then the factors that may affect the ability of individual' s hypoxia- resistant were analyzed in statistics. This paper has done this work by nonparametric statistics and correlation analysis , and got the conclusion that five factors, which are mountain sickness one have suffered before, sex, smoking frequency, bodily form and age, influence individual' s hypoxia- resistant ability. The conclusion makes a good sense, as it can provide statistics foundation for continuous iatrical research, while giving directive suggestion to reduce passengers' mountain sickness, and providing warranty for the design and amelioration of oxygen supplying system in Qinghai- Tibet railway cars .
