摘要
利用多重散射基础理论和修正的Fraunhofer近似及其相位函数,我们对过去F一近似下得到的颗粒的多重散射计算公式进行了改进。与理论值的相对误差的计算表明,我们的公式的准确性较原公式有了较大程度的提高。此外,我们也发现,随着光学厚度增加,多重散射光强的角分布的震荡减弱。
Based on the basic theory of multiple scattering and the corrected Fratmhofer- approximation, an inlproved formula for near- forward multiple scattering of particles have been obtained in this paper. The calculations of errors relative to theoretical results show that the accuracy of the past formula is improved. In addition, one can see that the fluctuations of angular distribution of the intensity decrease with the increasing of optical thickness.
