热辐射波在介质内的散射机理

Scattering mechanism of heat radiation wave in medium

从偶极子辐射理论出发导出了热辐射在介质内散射强度的一般表达式,确定了影响热辐射散射强度的主要因素．研究表明：入射辐射频率、阻尼振子的振幅等对介质的反射率、吸收率、透射率等热辐射特性具有决定性的影响．

A general equation about scattering intensity of heat radiation wave in medium was derived from viewpoints of the dipole radiation theory. The main factors, which affect the scattering intensity of heat radiation effectively, were ascertained. It was shown that the frequency of incident heat radiation and the swing of a damping oscillator in medium are of vital importance for the heat radiation properties such as reflectivity, absorptivity and transmissivity of medium.
