针对失重条件下人体出汗所发生的变化,采用航天医学领域的-6°头低位卧床(HDBR)实验与常规热舒适实验相结合的方法,在12种空气温湿度下对6名男性受试者进行不同部位皮肤微电流的实验测量,将皮肤微电流作为人体出汗的指示信号.研究结果表明:HDBR模拟失重时,空气相对湿度较低的条件下(${\rm{RH = 30\% }}$)人体皮肤出汗比HDBR卧床前需要更高的空气温度刺激,并且出汗率相比卧床前出现一定程度的降低;中等湿度(45%)条件下,模拟失重时的皮肤出汗率随着空气温度增高而增加,但是显著低于HDBR卧床前的水平;高湿条件(80%)下且环境温度高于29时,模拟失重时人体皮肤出汗率显著增高,其值低于HDBR卧床前的水平...

In order to study the changes of human sweating under simulated weightlessness, the -6°Head-Down Bed Rest (HDBR) experiment usually employed in the researches of Space Medicine and the traditional experiment of human thermal comfort were carried out. During the experiment, micro current of skin, which was presumed as an indicator of human sweating, was measured on 6 male subjects under different air temperatures and relative humidity. The results showed that higher air temperature was required under lower air humidity for sweating after HDBR, and the sweat rate was found to be lower than t...
