【摘要】 研究了一类非线性奇摄动方程。首先得到了外层解 ,利用特异极限阶定了激波层的几种可能位置 ,对激波层的几种不同位置利用伸长变量构造出内层解。最后利用匹配原则求出了原方程在整个区间上的渐进解更多还原

【Abstract】 This article is about a class of nonlinear odd perturbation equation.First,the external solution of the equation is obtained,and special limit is added to limit several possible location of the shock wave layer,then the stretched variable is used to work out the interior solution of the different location of the shock wave layer,last,the matching principle is applied to find the asymptotic solution of the original equation in the aggregate interval.更多还原
