从场协同原理的角度出发 ,分析了材料对热辐射能 (波 )选择性吸收过程 ,提出了材料对入射辐射能(波 )的作用实质是材料内阻尼振子组成的力场和入射辐射场之间的相互作用 ;调整这两个场之间的协同关系 ,可以改变和改善材料的选择性热辐射性能。基于此得到了强化材料对入射热辐射能 (波 )选择性吸收的机理。研究表明 :减弱入射辐射场与材料内阻尼振子组成的力场之间的协同关系 ,可以提高材料的吸收率和发射率 ;相反 ,强化这两个场之间的协同关系 ,可使材料表现出较高的反射率。
Based on the field synergy principle, the selective absorption process of thermal radiant energy (wave) is analyzed. The effect of the material on incident radiant energy (wave) is essentially the force field and the incident radiation field composed of damping vibrators in the material The interaction between these two fields can be adjusted and the synergistic relationship between these two fields can be changed and improved. Based on this, the mechanism of selective absorption of incident radiant energy (wave) by the strengthened material is obtained. The results show that reducing the synergistic relationship between the incident radiation field and the force field composed of damping elements in the material can increase the material absorption and emissivity. On the contrary, strengthening the synergistic relationship between the two fields can make the material Higher reflectivity.
