摘 要:
我们提出和研究一类带有阶段结构和时滞的捕食模型,得到了种群持续生存的充分条件。研究了阶段结构和时滞对系统稳定性的影响,获得了系统发生Hopf分支和稳定性的条件以及轨道渐进稳定的周期解的存在性。[著者文摘]

Abstract:
A delayed predator-prey model with stage-structure is proposed and investigated. Sufficient conditions for permanence are derived. We study the effect of the stage-structure and delay on the stability of the system,and obtain conditions for which the system enter a Hopf bifercation and stability. We also obtain the conditions for existence of an orbitally asymptotically stable periodic solution.[著者文摘]
