摘要
建立和分析了一类具有Holling Ⅱ CTL免疫反应且带有免疫时滞的病毒动力学模型.讨论了系统解的有界性,并通过分析平衡点处的特征方程,得到无病平衡点的全局稳定性和正平衡点稳定的条件.其结果推广了基本动力学系统,且可以用来解释免疫状态的复杂性.
In this paper,a model with time delays is built on the basic dynamic virus system. By analyzing the characteristic equation of the linearized system of original at the positive equilibrium,the stability of the positive equilibrium is discussed. It is found that time delays affect the stability of equilibrium. The results can be used to explain the complexity of the immune state and generalize the basic virus dynamics model.
