求n阶常数非齐次微分方程特解的新方法

The new method of solving special integral of n－ order linear inhomogeneous differential equation with constant coefficients

给出一种求 n阶常系数非齐次微分方程特解的新方法。这个方法较待定系数法、算子法、 Laplace变换法、 Lagrange变动参数法简捷。

The method is given.The method is simple and direct in contrast with Lagrange variation of parameter,waiting coefficients,operator method,or Laplace transform method.
