摘要
研究了自治的Lesile型具有时滞的2种群捕食系统正平衡点的稳定性,得到了稳定性对时滞长度的限制程度,讨论了该系统的Hopf分支现象,最后给出了一个例子进行验证。
The local stability properties of Lesile type two species predator-prey system with time delay is researched. As stability will impose restrictions on the length of time delay, Hopf bifurcation of the system is investigated. Finally, a example supporting the theoretical analysis is given.
