关于非齐次边界条件的处理

On the Treatment of Nonhomogeneous Boundary Conditions

在求解数理方程的定解问题时,常常遇到非齐次边界条件的情形.本文就几种常见的非齐次边界的定解问题分别加以讨论,指出如何选择一个适当的未知函数的替换,使原定解问题化为关于新的未知函数含齐次边界条件的定解问题.

In solving the definite solutions of mathematical equations,nonhomogeneous boundary conditions are often encountered.In this paper,several common definite solutions of nonhomogeneous boundary are respectively discussed.How to choose a suitable replacement of the unknown function and make the original definite solutions change into the definite solution about new unknown functions including homogeneous boundary conditions are pointed out.
