摘要
本文在 Hartel 多重光散射理论的基础上,导出了平面波照射下,具有任意尺寸分布的无吸收球形粒子多重散射光强角分布的表达式;引λδ—分布,用来近似地代替任意的尺寸分布,给出了便于数值计算的简单公式;对不同浓度,不同尺寸分布下的粒子多重散射光强角分布进行了数值计算,获得了稳定和精确的结果;以最简单的单尺度粒子为例,与 kerker,Woodward 等人给出的数据进行比较,结果相当地吻合。
From Hartel's theory the exact expression has been derived of the multiple light scattering angular distribution for high concentration of nor-absorption spherical partides having any number densities and sire distributions.Simple formula have been attained byusing δ-distribulion instead of any sire distribution.Stable and ac- curate results have been obtained of angular distribution of light scattering intensity for any partiecle system.The agreement between the paper's and kerker's is well for particles of the same size.
