摘要
研究了一类具有吸收效应的时滞病原体免疫模型.推导出系统的基本再生数与免疫再生数的表达式.通过运用Lyapunov泛函方法,分别给出了系统的无病平衡点、无免疫平衡点及地方病平衡点全局渐近稳定的条件.
A new delayed mathematical model for pathogen-immune with absorption was considered.The detailed expressions of the basic reproduction number and the immune reproduction number were derived.The conditions,under which the disease-free equilibrium,the immune-free equilibrium and the interior equilibrium are globally asymptotically stable,were given by using the method of Lyapunov functional,respectively.
