讨论了污染环境下具有时滞增长反应和营养再生的恒化器模型.得到了边界周期解全局渐近稳定的充分条件,进而得到了系统持续生存的充分条件.
In this paper,we consider a chemostat model with impulsive toxicant input and nutrient recycling.We obtain the sufficient condition of the global asymptotic stability of boundary periodic solution.Furthermore,the sufficient condition for the permanence of the system is obtained.
