摘要
利用匹配渐近展开法,讨论了一类边界层内有两个特异极限的具有多层现象的非线性奇摄动边值问题,得出了该问题的一致有效的零次渐近多层解.
Using the method of matched asymptotic expansions,a class of nonlinear singularly perturbed boundary value problems with multi-layer phenomenon in which there are two specific limits is discussed.And uniformly valid asymptotic multi-layer solution of the zero degree of the problem is given.
