摘要 建立了一类带有人口流动的SIR传染病模型,运用特征方程及辅助系统证明了无病平衡点的全局稳定性,得到了疾病在斑块间持续的条件. A SIR epidemic disease model with population movement is established.By means of characteristic equation and auxiliary system,the global stability of free equilibrium is proved.At last,the persistent condition of disease is attained.
