夏季常规温度对人体局部散热热流及温度的影响

Effect of summer temperature on human body′s dissipation heat flow and skin temperature

为了研究人体在夏季热环境中各个部位的生理变化情况,采用生理测试与主观问卷评价相结合的方法研究相同环境温度及湿度下,人体各个部位所受温度影响的差异大小.结果表明,在夏季常规温度25℃~31℃范围内,即使在相同的温湿度环境下,男女受试者的身体局部部位平均温度与平均热流也有较大的差异,其中部位变化最大的均为小腿,其他部位也有不同变化.

In order to study the physiological changes of various parts of the human body in the thermal environment, the differences of temperature and humidity in different parts of human body in normal temperature range are studied by the method of sampling physiological tests and subjective questionnaire evaluation. The results show that there is a great difference between the average temperature and the average heat flow in the body parts of male and female subjects in the range of normal temperature （25 ℃～31 ℃） in summer, even in the same temperature and humidity environment. The greatest changes are in the lower legs,and other parts of the body also have different changes.
