2) directional emissivity
方向发射率
1.
The optical constants (including the refractive index and the extinction coefficient) of some metals were numerically determined by applying experimental data of spectra reflectivity and the Kramers-Kronig relations and Fresnel reflect equation, and so the directional emissivity can then be calculated.
用红外光谱仪测定光洁金属表面反射率谱,再根据Kramers-Kronig积分式和Fresnel方程,计算出几种金属表面的折射率n(ω)和消光系数k(ω),然后使用n(ω),k(ω)和 Mcmahon关系式求出全波长方向发射率(0~90°)。
