电磁场分析中有关球谐函数项的应用研究

STUDY ON SPHERICAL-WAVE FUNCTION APPLIED IN ELECTROMAGNETIC FILED

本文通过严格的数学分析，讨论了电磁场分析中用到的球谐函数有关项的计算问题；推证出在坐标变换中，在θ＝０，π两个特殊位置上的任意取值不影响有关的电场量的计算值这一结论，并编程计算了一个实例。

In this paper,We investigate the spherical wave function,Which is applied in electromagnetic field computation,and its computation with mathematicaal analysis;We also prove that the value of(spherical coordinates) will not affect the value of the electrostatic potentieland filed in two special points(θ,π).We compute a real example.
