摘  要:
讨论了一类具有连续时滞和阶段结构的捕食-食饵系统,利用微分方程比较定理得到保证此系统持久性的充分性条件;利用迭代方法探讨了此模型的平衡点问题,得到保证此系统全局稳定的充分条件,并通过具体实例证明该条件是可行的.

摘  要:
A predator-prey system with time-delay and stage structure was discussed,some sufficient conditions which guaranteed the permanence of system were determined by using comparison theory;by means of an iterative method,sufficient conditions were derived for the global asymptotic stability of system.Finally an example showed that the conditions were feasible.
