摘要
为探明列车环境与旅客精神障碍的关系，作者对旅客精神障碍的发生及其所乘列车的环境因子进行了现场调查和监测。结果显示：９７％的患者是在超员状态发病的，车厢空气中的ＣＯ２平均值为０．２２６ｍｇ／ｍ３。旅客精神障碍的发病率随车厢人均容积的缩小而呈几何性增高，环境中的低气压、低气流及相对偏高的气温、气湿对旅客精神障碍的发生有共同促进作用（Ｒ＝０．９５３１）。由此认为：严重超员造成的旅行环境恶化是诱发旅客精神障碍的重要因素。
In order to study the relationship between environment and spirit obstacle among passengers travellers in the carriage,we investigated and researched the happening of the spirit obstacle among passangers and the environmental factors which caused the disease.The result appeared:97 percent of the diseases occured in the overcrowded carriage,the average concentration of CO 2 in the carriage was 0.226mg/m 3.the prevalance rate of the disease increased geometrically with the reduce of volume per.capita.The low air pressure and air current in the environment,relative high temperature and high damp improved the happening of the disease( R =0.9531).So we thought the bad environment caused by overcrowded carriage was the important factor which induced spirit obstacle,among the passengers.
