摘要
研究了环境污染下脉冲输入恒化器模型的动力学性质,得到了微生物灭绝周期解的全局稳定性和系统的持续生存.
In this paper, a chemostat model with periodically pulsed input in a polluted environment is considered. We show that microorganism-free periodic solution is globally asymp- totically stable. At the same time, we give the sufficient condition for the permanence of the model with the pulsed input.
