【摘要】 本文提出一种计算含微粒半透明介质辐射特性的蒙特卡罗方法，考虑了微粒群的独立多次散射，直接用米氏相函数考虑微粒的各向异性性质，计算了含微粒层的双向反射率与双向透射率。与实验数据和离散座标法的计算结果比较，吻合良好。更多还原

【Abstract】 This study introduces a Monte Carlo method for predicting the radiative characteristics of the simu-transparent medium containing the small particles and presents an analytical model of independent, multiple scattering. The anisotropic characterstics of the cloud of particles are considered directly using the Mie phase function. The bidirectional reflectivity and bidirectional transmittance of a flat containing the small particles are predicted. The caculating results are satisfactorily in agreement with the experimental data and the calculating results of the discrete ordinates method.更多还原
