摘要
主要建立了一类带有饱和治愈率和饱和接触率的SIRS传染病模型,研究得到了该模型的无病平衡点及地方病平衡点的局部稳定性,同时,借助构造Liapunov函数,给出了无病平衡点和地方病平衡点全局渐近稳定的条件.
In this paper,an epidemic model with saturated treatment rate and saturated contact rate is proposed.The local stability of the equilibriums(including disease-free equilibrium and epidemic equilibrium) are obtained.Moreover,by constructing a Lyapunov function,the global stability of epidemic equilibriums of the model are studied.
