摘　　要：文章利用M awh in的重合度理论,研究了一类具功能性反应三种群捕食———食饵时滞系统,得到了系统周期正解存在的充分条件。In this paper,we investigate a three - species predator - prey system with Holling Type Functional Response and Time Delay, by using Mawhin coincidence degree theory, a sufficient condition for the existence of positive periodic solution of the system is obtained.

关 键 词：时滞 正周期解 重合度
