【摘要】 高阶微分方程求解方法很多，但多为求实特征根，求虚特征根的方法也是在一定范围下的解．这里介绍一种用拉普拉斯变换法[3]求解高阶微分方程的方法．可不受范围条件限制．求出虚实特征根的微分方程解．更多还原

【Abstract】 There are a lot of ways to find the solution of the high-order differential equation. But most of them are to find the real latent root. Even though some of them is to find the imaginary one,it is under given conditions. So we recommend a way to solve a class of high-order differential equations with laplace transform. It may solve the real and imaginary lalent root without any rang limit.更多还原
