| Abstract: | In this paper,a class of singularly perturbed boundary value problems for elliptic equations are considered.Under appropriate conditions ,the formal solution of the singularly perturbed problem including boundary layers is constructed,and the uniformly validity of the formal solution is showed by using maximum principle. |
