摘　　要：采用了Eikonal近似方法对旋转微椭球体颗粒光散射进行了理论研究,并把旋转微椭球用其等效的球来近似,进而应用Mie散射理论对旋转微椭球体颗粒光散射进行数值计算,并对计算结果进行了分析。结果表明,旋转微椭球体颗粒散射光振幅分布与其位置(θ0、0)、离心率及入射光波长有关,并与其内、外切球的光散射情况接近。We have studied the light scattering characteristics of revolution microspheroid by using Eikonal approximation method and approximate the revolution microspheroid by its effective spheres so that we can use Mie scattering theory to calculate and analysis it.The results show that the distribution of the amplitude of the scattered light is related to its position (θ0、0),ecentricity and incident wavelength,and its results approach the case of a sphere.
