摘要 研究一个具有一般非线性发生率的SEIQR流行病模型,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,无病平衡点是不稳定的;当R0>1且p<α1+σ成立时,地方病平衡点是全局渐近稳定的。 The SEIQR epidemic model with a general nonlinear incidence is mainly studied. If the basic reproductive number R0≤1,the disease-free equilibrium is globally asymptotically stable; if R0 1,the disease-free equilibrium is unstable. If R0 〉1and p 〈α1+ σ are satisfied,the endemic equilibrium is globally asymptotically stable.
