以问卷调查的方式,对低压环境下人体皮肤温度随空气压力的变化及其对人体热感觉的影响进行了研究。结果表明,在其他环境参数一定的条件下,人体平均皮肤温度和人体热感觉均随压力降低而降低,且二者变化趋势基本一致。经过统计学分析可知,二者在低压环境下具有较好的相关性,因此在低压环境下皮肤温度可作为表征人体热感觉的一个重要指标。
By means of questionnaire survey, the changes of human skin temperature with air pressure under low pressure and its influence on human thermal sensation were studied. The results show that under certain conditions of other environmental parameters, the average skin temperature and the human body thermal sensation decrease with the decrease of the pressure, and the trend of the two is basically the same. After statistical analysis, the two have good correlation under low pressure environment, so the skin temperature can be used as an important indicator of the human body’s thermal sensation under the low pressure environment.
