摘 要：<正> From the microstructure of heat radiation, the interaction between the incident heat radiative wave and the electromag-netism syntonic wave is analyzed to reveal the emission, absorption, transmission and reflection mechanisms of the incident heat ra-diative wave in materials. Based on Lorentz dispersion theory, the effect of optical parameters on heat radiative characteristics is also analyzed. The method of ultra-attenuation and nanocrystallization improving the heat radiative characteristics of the material and the emissivity dispersion of the ultra-attenuated materials are brought to light.
