摘　　要：应用上、下解方法和抛物型方程的极值原理,研究了带存放率的竞争扩散系统 ut-D1△ u=u(a-bu-cv)+h,vt-D2△v=v(d-eu-fv)+k在齐次Neumann边界条件 下解的渐近性态.In this paper, the asymptotic behaviour of solutions of competition diffusion system with depositings ut-D1△u= u(a-bu-cv) + h, vt- D2△v = v(d-eu-fv) + k with homogeneous Neumann boundary condition is considered by using the method of upper and lower solutions and the parabolic maximum principle.

关 键 词：竞争扩散系统 解的渐近性态 上、下解
