输运方程中的散射相函数

Scattering Phase Functions in Transport Equation

散射相函数在输运方程计算中具有十分重要意义,各文献中对散射函数的描述很少。为方便对散射函数做综合研究,对国内外文献中出现的分布函数(散射相函数)做了整理总结。所提到的散射相函数涉及反应堆物理、天体物理、大气辐射输运的等多个专业,其求解方法都具有相似性,并对这些分布函数的处理方法给出一个定性的概念,对从事输运计算的科研人员有着一定的参考价值。

Scattering phase function plays an important role in the transport computation. Few of literatures concern about the description of scattering phase function. In order to make a comprehensive research, this paper presents on a survey on the distributed functions （ scattering phase functions）. The theoretical calculation of the scattering question relating to reactor physics, astrophysics, as well as the atmospheric radiation transport, uses similar solving methods. The paper describes a qualitative concept of processing methods of these distributed functions, which could be useful for research in transport computing.
