具有连续预防接种的饱和接触率的SEIQR流行病模型的定性分析
he analysis of SEIQR epidemical model with continuous vaccinal immunity and saturated contact rate
研究了一类具有预防接种免疫力的SEIQR流行病模型的全局稳定性，找到了决定疾病绝灭和持续生存的阈值---基本再生数R_{0}，证明了无病平衡点和地方病平衡点的存在性及全局渐近稳定性，揭示了隔离和预防接种对疾病控制的积极作用。
he global stability of SEIQR epidemiological model with continuous vaccinal immunity and saturated contact rate is discussed.The threshold ,basic reproductive number which determines whether a disease is extinct or not,is obtained.The existences and global stabilities of the disease-free equilibrium and the endemic equilibrium are solved and active effects of quarantine and continuous vaccinal immunity are exposed.
