摘要 考虑了一个时滞变系数SIR传染病模型,并获得了含有时滞的下界,且不同于其它文章的系统持久性条件,进一步给出疾病灭绝的充分条件.其目的是讨论变系数及时滞对系统持久与疾病根除的影响. We consider an SIR epidemic model with variable coeffcients and time delay,and obtain a low boundedness with delays and the condition which is different from some results of other papers for the permanence of system.Further,suffcient condition for the infective individuals to become extinct is given.The main purpose of this paper is to study the effect of time delay(incubation) and variable coefficients on permanence of population of the SIR model.
