Experiment on effects of air pressure on human skin temperature and thermal sensation

Studies the change of human skin temperature with air pressure and its influence on human mean thermal sensation(MTS) by using questionnaire in low-pressure environment. The results show that the mean skin temperature and MTS decrease with the pressure dropping, and have the same tendency, when other environmental parameters keep constant. By statistic analysis, finds that the mean skin temperature associates MTS significantly, so the skin temperature could be used as an important index to indicate human thermal sensation in low-pressure environment.
