摘　　要：研究时标上具有捕获率和投放率的Holling Ⅲ型捕食系统,考虑了时滞效应,基于时标Mawhin重合度理论方法,得到了系统至少有一个正周期解.A HollingⅢpredator-prey system with exploited terms and stork on the time scales is studied.Considering the time delay effect,the system has at least one positive periodic solution based on the Mawhin coincidence degree theory on the time scales.

关 键 词：捕获率 投放率 时标 HollingⅢ型捕食系统−食饵系统 捕食者−食饵模型
