这里为大家介绍下emissivity 是什么意思，希望能帮助到各位朋友。

中英文翻译

n.

发射率，辐射系数。

The emissivity of a material (usually written ε or e) is the relative ability of its surface to emit energy by radiation. It is the ratio of energy radiated by a particular material to energy radiated by a black body at the same temperature.
