摘要
建立了在固定时刻具有脉冲效应的三维捕食系统，利用常微分方程比较原理、含脉冲的比较原理及Lyapunov函数方法，得到了该系统的持续生存性、周期解的存在唯一性和全局吸引性，并给出了保持这些性质时脉冲项应满足的界限。
A three-species predator-prey system with impulse and Holling Ⅳ functional response is discussed. The persistence, the existence and the uniqueness of periodic solution are proposed by the global attractivity with Comparison theory and Lyapunov function of differential equation. Prior bounds are given to keep these qualities of the system.
