摘要

本文针对二阶线性齐次微分方程的线性非齐次边值问题，通过对其解式的分析和简化，获得了解式的相似结构；提出了一种由一个基本边值问题的解去构造出较为复杂边值问题的解的一种新方法，有利于解决相应的应用问题。 The solution’s formal similarity is gained by reducing the analytical expression of linear non-homogeneous boundary-value problems for second-order linear homogeneous differential equations, a new me- thod is provided to construct solution of equation with complex boundary conditions by employing simple boundary conditions.
