摘　　要：该文用矩阵元素表示偏振激光束入射时与入射方向垂直的平面上散射光的偏振特征,介绍了使用Muller-Stokes算法来研究随机分布群粒子场侧向散射光性质的方法。用此算法对实验得到的数据进行计算得到的结果表明,散射光强的分布是呈轴对称的,散射光各种偏振特性的变化及用于表示各种特性的矩阵元素主要决定于散射粒子的大小。另外,散射系数亦随粒子直径的变化而变化。The matrix elements are calculated to represent the scattering characteristics of the scattered radiation in the plane vertical to the incident polarized laser beam, and a new method using Muller-Stokes algorithm to study the characteristics of the radiation side-scattered by the multiple particles distributed randomly is introduced. By calculating the experimental data using this algorithm, the results show that the intensity of the scattered radiation is axially symmetric and that the variations of the characteristics of the scattered radiation and the matrix elements representing the scattering characteristics depend primarily upon particle sizes. In addition, the fraction of the scattering varies dramatically with particle diameters.
