The Exponential Asymptotic Solution of Differential Equation

摘要: 本文对常微分方程的指数形式渐近解作了进一步讨论,首先给出了二阶方程一致有效指数形式渐近解的正交条件;接着讨论了匹配渐近法中的指数形式渐近解;最后举例说明。

Abstract: In this paper, the exponential asymptotic solution (E. A. S.) of differential equation is discussed Firstly, E. A. S. of the second-order differential equation is studied and the orthogonal conditions of the uniformly valid E. A. S. are found out.Next,E.A.S.in matched asymptotic method is discussed, Finally, some examples are give.
