Radiation Cooling of Body
身体的辐射冷却
|
The basic heat transfer equation for radiation is
辐射的基本热传递方程是
where A is the area of the human body and
e is the emissivity of the skin. In this case the temperatures must be in Kelvins.
其中A是人体的面积,e是皮肤的发射率。在这种情况下,温度必须以开尔文为单位。
A typical body area according to physiology texts:

Human skin is a near-ideal radiator in the infrared. For a perfect radiator e=1.
e = 0.97 The Stefan-Boltzmann constant:
 Thot = 307K, Tcold = 296K.
根据生理学教材,典型的体表面积:人体皮肤在红外波段近似为理想辐射体。对于理想辐射体,e=1。e = 0.97 斯特藩-玻尔兹曼常量:T_hot = 307K,T_cold = 296K。 |
Data may be entered for any of the parameters below, and the heat loss rate by radiation will be calculated. Default values will be entered for unspecified parameters, but all values may be changed.
可以为以下任何参数输入数据,计算出通过辐射的散热率。未指定的参数将输入默认值,但所有值均可更改。
Q/t 等于瓦特。 中文译文中的待填/计算数值依次对应:1:q。实际数值以上方原输入框为准。 |
