摘　　要：本文详细地分析了热辐射在介质中的吸收过程 ,以及超细化对物体辐射性能的影响 ,提出了提高材料热辐射性能的超细化方法。实际应用和理论分析都表明将材料超细化后可以增加热辐射的透射深度 ,从而能够提高材料的发射率与吸收率。辐射节能涂料今后的研究方向之一就是朝着超细化。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.
