发射率

Emissivity

材料的辐射率是其表面通过辐射发射能量的相对能力。 它是由特定材料辐射的能量与在相同温度下由黑体辐射的能量的比率。 真正的黑体将具有ε= 1,而任何真实物体将具有ε\u003c 发射率是无量纲的。 通常,非金属表现出高发射率,而金属根据金属的类型及其表面状况变化很大。 具有高抛光表面的金属倾向于显示低发射率,而粗糙的氧化金属倾向于显示较高的金属。 例如,高度抛光的银的发射率约为0.02。 可见表面颜色通常被误认为是总辐射率的重要因素; 它影响可见波长的光谱发射率,在计算总辐射率时通常可以忽略不计。 The emissivity of a material 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. A true black body would have an ε = 1 while any real object would have ε < 1. Emissivity is a dimensionless quantity. In general, nonmetals exhibit high emissivity, whereas metals vary greatly depending on the type of metal and its surface condition. Metals with highly polished surfaces tend to exhibit low emissivities, whereas roughened, oxidized metals tend to exhibit higher ones. For example, highly polished silver has an emissivity of about 0.02. Visible surface color is often mistaken as a significant factor in total emissivity; it affects the spectral emissivity at visible wavelengths, which are often negligible when calculating the total emissivity.

在英语 词典里emissivity的定义

字典中发射率的定义是衡量表面辐射能量的能力; 在相同温度下单位面积的辐射通量与黑体辐射的辐射通量之比ε。

The definition of emissivity in the dictionary is a measure of the ability of a surface to radiate energy; the ratio of the radiant flux emitted per unit area to that emitted by a black body at the same temperature ε.
