人体及其环境之间辐射换热的计算,房间中平均辐射温度的计算,以及辐射环境的其它问题都要采用角辐射系数值。不过,对于人体几乎不可能有解析表示的精确角辐射系数。目前有两个计算方法。一是将人体作为当量的简单固体模型,例如,球面元和圆柱面圆,等等。另一方法是用器械积分器和摄影方法之类测量真实人体的角辐射系数。

The calculation of the radiation heat transfer between the human body and its environment, the calculation of the average radiation temperature in the room, and other problems of the radiation environment must adopt angular radiation coefficient values. However, it is almost impossible for the human body to have an accurate angular emissivity expressed analytically. There are currently two calculation methods. One is a simple solid model that uses the human body as an equivalent, for example, a spherical element and a cylindrical surface circle, and so on. Another method is to measure the angular emissivity of an actual human body with an instrument integrator and a photographic method.
