摘　　要：研究了一类具有无穷时滞竞争扩散模型的周期解问题,采用了上下解的方法,获得了周期解的存在唯一性,并给出了解的渐近性态.In this paper, a competition diffusion system with infinite delay is considered. A sufficient condition of uniqueness of the system subject to Neumann conditions is given, and asymptotic behavior of the solutions of the corresponding initial boundary value problem is obtained.

关 键 词：竞争扩散模型 时滞 上下解 周期解
