求几类微分方程特解的简捷方法

A New Approach to the Special Solutions for Some Kinds of Differential Equations

常系数线性非齐次微分方程的特解一般都是用待定系数法或常数变易法求得的,但运算量都比较大。本文作者针对几类常见的特殊微分方程,介绍了一种运算量很小的简捷方法求其特解。

In this paper, the method is given to search the special solutions for some kinds of special differential equations,and a new approach to the solutions is introduced.
