摘要
研究了不连续的抗生素输入以及时滞效应对栖生的两菌群的影响,获得了菌群灭绝和持续生存的条件.结果表明抗生素的不连续输入对系统的动力学行为带来很大影响,而抗生素的时滞作用是无害的.
In this paper,we investigate the dynamics of a two bacterial species model with the effects of antibiotics discontinuous input and time delay.The conditions of extinction and persistence about the system are obtained.Our results show that discontinuous antibiotics input can bring great effects on the dynamics of the system,and antibiotics time delay is harmless.
