摘要
本文通过利用未知函数的线性变换和自变量变换,将一类变系数线性微分方程化成二阶常系数线性微分方程,从而得到变系数二阶线性微分方程的一个新的可解类型.
In this paper, a kind of linear differential equation with variable coefficients is turned into second order linear differential equation with constant coefficients through linear and self- variable transformation of unknown function, then a new solvable type of second order linear differential equation with variable coefficients is obtained.
