摘要
建立了一类带有非线性传染率的SIRS传染病模型,得到基本再生数R0.当R0≤1时,无病平衡点是全局渐近稳定的;当R0>1时,地方病平衡点是全局渐近稳定的.
A SIRS epidemic model with a nonlinear incidence rate is estalished. The basic reproductive number is found. whenR0"1,disease free equilibrium point is globally asymptotical stable; whenR0 1,endemic equilibrium is globally asymptotical stable.
