摘要 讨论了具有垂直传染且总人口在变化的连续预防接种SIRS传染病模型,给出了基本再生数R_0的表达式,并利用广义Bendixson-Dulac函数方法证明了无病平衡点和地方病平衡点的全局稳定性. This paper considers an SIRS epidemic model with vertical infection, a varying total population size and continuous vaccination. The basic reproduction number R0 is identified, and given a complete analysis by using a generalized Bendixson - Dulac function.
