【Abstract】 The absorption of radiative heat by medium and the effect of ultra-attenuation on the radiative characteristics are analyzed.Enhancement measures of the radiative characteristics of medium is brought to light by ultra-attenuation.Decreasing particle size of coating can increase the transmission depth of radiative heat and get higher emissivity and absorptivity.Ultra-attenuation and nanocrystallization will bring a brilliant prospect to the development of heat radiative coating.更多还原
