一层随机分布球形粒子的被动辐射特性研究

一层球形粒子的被动辐射特性一直没有被全面系统地进行研究.文中基于矢量辐射传输方程,对一层随机分布的球形粒子进行数学建模,采用特征值特征向量法分别计算了瑞利球形粒子和Mie球形粒子,得到了两种粒子在各种不同参数条件下的辐射亮度温度,研究了模型中的参数对粒子被动辐射特性的影响并加以分析,给出合理的物理解释以保证数据的正确性,该研究结果可以为以后将矢量辐射传输方程应用到对单个大尺寸粒子的被动辐射特性的研究提供基础.

Characteristics of the Passive Radiation for Layer of Spherical Particles with Stochastic Distribution

The passive radiation characteristics of a layer of spherical particles have not been studied systematic.passive vector radiation transfer equation was applied to build the mathematical model of a lay of spherical particles randomly distribution,then the eigenvalue and eigenvector method was used to calculate the MIE particles and Rayleigh particles,the characteristics of the passive radiation of these two kinds of particles were observed and studied by analysis the date,furthermore,the relationship between the parameters in the model and the properties of the two kinds of particles was discussed in this paper,and corresponding physical interpretation was also proposed to ensure the correctness of the date in this paper,these result will provide a basis for applying the VRT equation into the study of passive radiation characteristics of a single large size particle.
