讨论了一类两参数奇摄动燃烧Dirichlet边值问题.利用伸长变量,构造了问题解的边界层和内部层,并且得到了原问题的形式渐近解.再利用微分不等式证明了解的一致有效性.
A class of singularly perturbed combustion Dirichlet boundary value problems with two parameters was considered.Using the stretched variables,the boundary and interior layers of the solution to the original problem were constructed,and the formal asymptotic solution was obtained.And by using the differential inequality the uniformly validity for the solution was proved.
