研究具有隔离仓室及饱和接触率的非线性高维自治微分系统SEIQR流行病传播数学模型,得到疾病绝灭与否的阈值一基本再生数冠),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,揭示了隔离对疾病控制的积极作用,推广了已有的研究结果。
A kind of non-linear high dimensional autonomous differential system, SEIQR epidemic model with saturated contact rate, containing quarantine is studied. 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 are exposed. The results which have been researched are extended.
