摘要

基于T矩阵方法,给出了随机取向、轴对称、含核椭球粒子的散射计算方法.散射体的核和外壳均可为非球形粒子,整个粒子具有轴对称性.以含核椭球粒子为模型,计算了含有吸收性内核(黑炭,black carbon)的水凝物气溶胶的散射特性,分析了核的大小、形状对消光系数、散射系数、吸收系数、不对称因子、单次散射反照率以及Muller矩阵等的影响.

A computer method is described to calculate the light-scattering properties of randomly oriented, axially symmetric coated particles, in the framework of the T-matrix theory. Both the core and the shell can be axially symmetric nonspheroidal particles. Based on the coated spheroidal particle model, light scattering characteristics of water aerosols with an absorptive core (black carbon) are calculated. The effects of cores with different sizes and shapes are analyzed on extinction efficiencies, scattering efficiencies, absorption efficiencies, single scattering albedos, asymmetric parameters.
