| 摘 要： | 本文考虑了红外辐射源腔内的镜反射成份,采用镜-漫混合反射模式,用蒙特卡罗法求定空腔的定向有效发射率。在通解的数学模型基础上,还针对500K双锥-圆筒热管空腔求得其典型解,分析了空腔辐射特性与锥角的关系。利用本文提供的方法也可计算其他腔形的辐射特性。

| Abstract: | The specular reflection component within standard radiant source used in infrared region is considered in this paper. Using the uniform specular-diffuse reflection model and the Monte-Carlo method, we have calculated the directional effective emissivities of the 500K cylindro-double cones cavity. The quantitative analysis between the values of cones and directional effective emissivity has been estimated. Based on the general mathematical formulation proposed in the paper, the radiant emission characteristics of other cavities can also be evaluated. |
