本文研究了一类两参数非线性奇摄动边值问题的基本模型.利用奇摄动方法,对该问题解的结构在两个小参数相互关联的三种不同情形下作了讨论,得到了该问题的渐近解并证明了在三种情形下不同的解的结构与渐近性态.
A class of basal model for the nonlinear singularly perturbed boundary value problem with two parameters is studied.Using the singular perturbation method,the structures of solutions for the problem is discussed throughly in three different cases about two small parameters.The asymptotic solutions of the problem are given.The different structures and asymptotic behavior of solutions in the three cases are proved.
