摘要
本文对右端函数f（x）为Pm（X）及Pm（X）eλx（Pm（x）是m次多项式）的常系数线性非齐次微分方程给出了一种用除法形式求特解的简便方法。
This paper provides an easy way to find the particular solution--through division--to a constant coeffieient linear nonhomogeneous differential equation in which the right--hand function f(x) is pm(x) exx (pm(x) is the polynomial to the mth degree).
