摘要
首先讨论变系数线性微分算子因式分解式的存在条件 ,并且给出微分算子因式分解的一些技巧 ,然后给出变系数线性微分方程算子解法的两种方法 .
We first discuss the codition of the existence for the factor of linear differential operator with variable coefficient, otherwise give some techniques for factorization of differential operator. Then give two techniques of the operator method to find the general solution of linear differential euqation with variable coefficient.
