基于正交试验的低气压环境中人体热舒适研究
Study on human thermal comfort under low-pressure environment based on orthogonal test method
摘要：
通过正交试验，以问卷调查的方式进行了低气压环境下人体热舒适性的实验研究，重点分析了温度、压力和风速对受试者平均热感觉MTS影响的显著性。结果表明，在75.994～101.325 kPa（0.75～1.00 atm）的压力范围内，压力对人体平均热感觉MTS的影响仅次于温度，风速的影响最小。

Abstract：
Carries out experiment on human thermal comfort under low-pressure environment, which is designed by orthogonal test method and thermal sensation is obtained by questionnaire. Analyses emphetically the significance of air temperature, pressure and air velocity on mean thermal sensation (MTS). The results show that air temperature is the first significant factor affecting MTS and the second is air pressure, and the influence of air velocity is little under low pressure environment of 75.994～101.325 kPa (0.75~1.00 atm).
