摘要
文章通过对一类传染病的传染途径分析,建立了一个具有隔离和注射疫苗的传染病差分方程模型,并借助Jury判据对模型进行讨论,得到了系统无病平衡点和地方病平衡点局部渐近稳定的充分条件.
We will make an analysis on the spread roads of the epidemic in the paper,then build a difference equation model with quarantine and vaccination.The model is discussed by Jury criterion.For the disease-free equilibrium and the endemic equilibrium,the sufficient conditions of partical asymptotical stable are obtained.
