摘　　要：本文对伴有边界摄动的积分微分方程组边值问题的奇摄动,通过对角化技巧,利用逐步逼近法证明了解的存在,从而得到了解的按范数界限估计的一致有效的渐进展开式.In this paper,the existence of solution of differential equations boundary value problems is given by diagonalization technique and successive steps approxi- mation approach. Then the solution of uniform efficient asymptotic expansion equation according to norm boundary estimating is obtained.
