| 摘 要： | 众所周知,对于泛定方程的非齐次边界条件的处理,通常是选取一个适当的未知函数之间的代换,使对新的未知函数,边界条件是齐次的.那么,对于一个具体方程代换如何选择呢?代换的选择可以多种多样,可是很多学生遇到这样的问题经常会无从下手,那么有没有通用的一个代换呢?本文就此进行研究,给出对三类非齐次边界条件都适用的变换.

| Abstract: | As we all know,for the pan-setting equation with non-homogeneous boundary conditions of treatment,an appropriate substitution of unknown function is usually selected,so that for the new unknown function,the boundary conditions are homogeneous.How to select a substitution for a specific equation is a problem for many students.This research paper proposed a transform for three types of non-homogeneous boundary conditions. |
