常微分方程教学中一种变换与应用

A Transformation in Ordinary Differential Equations

本文通过常微分方程教学所引进的一种变换，结出了采用这种变换来求常系数非齐线性方程与非齐欧拉方程的特解，以及对求积分的应用．

A transformation recommended in the teaching of ordinary differential equations to help us find the particular solutions of both nonhomogeneous linear differential equations with constant n coefficients and nonhomogeneous Eulsr's equations' Its appliCations to integrals is also discussed.
