| Abstract: | In this paper , we study the singular perturbation of boundary value problem for a class of thira-order semilinear equation with two parameters. By the different quantity step of two parameters, we disscuss the boundary layer phenomena of different characters of perturbed solution, and give the umiformly valid asymptotic expansion of the different characters of perturbed solution, and give the umifornly valid asymptotic expansion of the solution. |

| Keywords: | semilinear two parameters singular perturbation asymptotic expansion |
