摘要
通过反向应用射线踪迹法并与漫反射表面的有效辐射强度相结合来分析含漫射表面半透明体的表观光谱发射特性。漫反射表面的有效辐射强度通过迭代离散区域的能量平衡方程并结合反向应用射线踪迹法进行求解。将该方法与半透明大平板表观发射率的解析解及圆盘状半透明体表观发射率的蒙特卡洛方法数值解进行了比较，并用该方法对圆盘状半透明体的表观发射进行了分析。
Combined with the radiosity intensity of diffusely reflecting surfaces, the improved ray tracing method is reversely employed to analyze the apparent spectral emissivity of a body of semi transparent medium having some diffuse surfaces. The radiosity intensities of a diffusely reflecting surface are obtainde by iteratively solving the energy balance equations of all discrete zones and using the ray tracing method reversley. The apparent emissivity results obtained by this method are separately compared with the exact solutions of the semi transparent slabs and the numerical values of disc bodies of semi transparent medium gained by Monte Carlo method, and the apparent emissivity of a disc body is investigated.
