摘要 本文基于微分方程稳定性分析,利用Lyapunov方法研究了一类传染病模型的无感染平衡点稳定性判据,即基本再生数阀值小于1。 Based on the stability analysis of differential system, we obtain the stability criteria for infect-free equilibrium of a class of endemic disease by the Lyapunov method. This stability criterion is the reproduction ration is less than 1.
