在低气压环境下对两节点模型进行了修正，同时通过实测皮肤温度验证了其准确性。在此基础上对热环境评价指标---标准有效温度（SET *）进行了计算，分析了低气压下SET *的变化规律，并在不同低气压环境下对 ASHRAE Standard 55中的舒适区进行了修正。计算结果表明，在相同环境参数条件下，随着大气压力的降低，对应的标准有效温度降低。相应地，随大气压力的下降，人体舒适区范围向干球温度较高的方向移动。低气压环境下舒适区对应的干球温度上下限值均比常压下高，且温差范围增大。

Revises the two-node model in low pressure environment,and verifies its accuracy by measuring skin temperature.On this basis,calculates the standard effective temperature (SET* )-the thermal environmental evaluation index,analyses the variation of SET* in low pressure environment,and revises the comfort zone of ASHRAE Standard 55 in different low pressure environments.The calculation results show that in the same conditions of environment parameters,the corresponding standard effective temperature falls with the decrease of atmospheric pressure.Accordingly,the range of human-body comfort zone moves to the higher dry bulb temperature direction with the decrease of atmospheric pressure. The upper and lower limits of dry bulb temperature of the comfort zone in low pressure environment are higher than those in standard atmospheric pressure environment,and the range of temperature difference increases.
