摘要
从波动力学的观点出发,解析了热辐射波和材料内部的阻尼谐振子之间的相互作用过程,从而揭示了热辐射波在材料内部的发射、吸收、透射和反射机理。基于洛伦兹色散理论,分析了影响材料选择性热辐射的因素,提出了改善材料选择性热辐射复合化和超细化方法。实验研究证实了这些方法的正确性和可靠性。
From the viewpoint of wave mechanics,the interaction between the incident heat radiative wave and the damping harmonic oscillators in materials is analyzed to reveal the emission,absorption,transmission and reflection mechanism of incident heat radiative wave in materials.Based on the Lorentz dispersion theory,the main effects on the heat selective radiation are also analyzed and the multi-component and ultra-attenuation methods improving the radiative selectivity of materials are brought to light in this paper.It is proved that multi-component and ultra-attenuation can ef-fectively improve the selective radiation and greatly increase the emissivity and absorptivity of materials both theoretically and practically.
