摘要 本文研究了一类具有饱和发生率的离散SIS传染病模型的动力学性态.通过定义模型的基本再生数,得到了无病平衡点和地方病平衡点的存在性,讨论了无病平衡点和地方病平衡点的全局稳定性. A discrete SIS epidemic model with the saturation incidence is formulated and studied. The basic reproductive number is defined. The existence and stability conditions of disease free equilibrium and endemic e- quilibrium are obtained.
