摘要 利用重合度理论,研究一类食饵有扩散的脉冲Holling-Ⅲ型时滞捕食者—食饵系统,证明并得到了系统正周期解存在的充分条件。 In this paper, a class of delay periodic predator - prey system with functional response （ Holling - Ⅲ ） and impulsive effect and diffusion is studied. By means of the coincidence degree theory, the authors estabilish a sufficient condition for the existence of positive periodic solution of the model.
