摘　　要：在Ｍｉｅ光散射理论对单个颗粒光散射计算的基础上，应用蒙特卡罗直接模拟方法实现对颗粒群的复散射计算，得出了不同粒径及分布、不同颗粒浓度条件下，颗粒群的复散射光强分布．该方法可用于在线颗粒测量中的复散射计算．Based on the Mie light scattering theory in light scattering calculation of single particle, the calculation of multiscattering of particles using Monte Carlo direct sumulation is carried out. The distribution of light scattering intensity of different particle size, of different size distribution and of different particle concentration is obtained. The method offered can be used in the light multiscattring calculation of on-line particle measurement.
