摘要
建立一类具有接种和隔离的传染病模型,给出了无病平衡点的局部稳定性,并通过分支分析得到了系统产生后向分支的条件.
An epidemic model with vaccination and quarantine is formulated.The local asymptotical stability of disease-free equilibrium was investigated.The conditions for the system producing backward bifurcation were obtained by bifurcation analysis.
