摘　　要：该文讨论了具有非单调发生率SIS流行病模型,分别建立了带有分布时滞和离散时滞形式的感染个体的恢复时滞模型,同时分析了系统平衡态的稳定性.In this paper, an SIS endemic model with nonmonotone incidence rate are investigated. To model the recovery time of infected populations, a recovery delay, both in distributed and discrete form is introduced. The dynamical behavior of the models is investigated from the point of stability.

关 键 词：非单调发生率 时滞 全局稳定性
