| Abstract: | 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. |
