| 摘 要： | 本文利用蒙特卡罗方法计算准直光束通过薄层随机分布粒子散射的透射和反射光强,并和输运理论的扩散近似结果做了比较。当散射接近各向同性时两者符合良好。当散射明显地成为各向异性时,蒙特卡罗方法的结果是合理的,而输运理论的扩散近似失效。

| Abstract: | We use the Monte-Carlo method to calculate the intensities of transmission and reflection of a collimated light beam scattered from randomly distributed particles in thin layer. The results obtained are compared with those calculated by the transport theory of diffusion approximation. When the scattering is nearly isotropic, both of the results agree well. When scattering becomes anisotropio, the results from Monte-Carlo method are reasonable, while the theory of isotropio scattering approximation becomes invalid. |
