| Abstract: | 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. |
