摘要
本文研究一类带耦合项的化学反应扩散方程组解的性态，利用上下解理论证得解的存在性，然后在一定的参数环境下考虑了相应的奇摄动问题，并给出一致有效的渐近解。
In this paper,singular perturbation for a class of coupled chemical reaction diffusion system with initial and Neumann boundary conditions is considered. Under some suitable conditions and restrictions,we obtain a uniformly valid asymptotic solution of the stated system by using the iteration method and the method of upper and lower solutions.
