The analysis of surface effect is based on defect reaction and diffusiontheory, the study for surface effect will have good guidance to the improvement of electrical properties.
The fire was modeled by the mixture fraction combustion method with chemical reaction mechanisms neglected. Laminar diffusion flame theory with one-step irreversible fast reactions is assumed.
In this paper we study the asymptotic property of solutions of a class of reaction-diffusion systems including those appearing in the theory of epidemics and combustion.
