摘　　要：拉普拉斯变换是求解n阶常系数线性微分方程的重要方法,而一般的常微分方程教材对此叙述都比较简略。文章对此作了探讨,阐述了拉普拉斯变换在求解n阶常系数微分方程中的作用及意义。Laplaece transform is an important method to End the solution of n constant coefficient linear differential equations and common ordinary differential equations teaching materials only simply explain this way. The question is discussed in the thesis. Function and meaning of Laplace transform in finding solution of n constant coefficient linear differential equations are expounded.
