摘要

应用球谐近似于电子输运方程，得到各级球谐矩满足的双曲型方程组。给出了相应的初始和边界条件以及Lax-Wendroff格式。由此而得到稳定的数值解。计算了均匀分布于无限高矩形空腔的电子源在此空腔中的能量沉积分布和能量沉积系数。

Abstract

Using the spherical harmonic approximation to solve electron transport equation, a set of hyperbolic differential equations that governs spherical harmonic moments has been obtained. Correspondingly, a set of initial and boundary conditions has also been given. Utilizing the Lax-Wendroff numerical scheme, the stable numerical solutions which include electron energy deposition in the cavity and its energy deposition coefficients have been obtained.
