本文研究了一类双参数非线性反应扩散奇摄动问题的模型.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情形下作了讨论.得到了该问题的渐近解,由解的展开式看出本问题的解同时具有初始层和边界层.
In this paper,a class of models for nonlinear reaction diffusion singularly perturbed problem with two parameters is studied.Using the singular perturbation method,the structure of solution for the problem is discussed related two small parameters.The asymptotic solution of the problem is given.And from the expansion for solution,it shows that there are initial layer and boundary layer at the same time.
