本文研究一类具有增长时滞及脉冲输入的Beddington-DeAngelis恒化器模型,得到了微生物灭绝周期解存在和全局吸引的条件,并证明了系统在适当的条件下是持久的.
The dynamical behaviors of a Beddington-DeAngelis chemostat model with delayed response in growth and pulsed input was studied in this paper.We obtaine that some conditions for the existence and the global attractivity of a ‘microorganism-extinction’ periodic solution and prove that the system is permanent under other conditions hold.
