摘要
建立了一个具有脉冲和时滞的模型来描述一类具有脉冲接种和染病潜伏期的疾病。运用时滞微分方程和脉冲微分方程的理论,得到了系统持久性的充分条件。
In this paper, we established a model with impulsive and delay to describe a class of impulse inoculation and incubation period infected disease. The sufficient co-nditions of system persistence are obtained by applying the theory of delay differential equation and impulse differential equation.
