研究了一类具有脉冲收获和Hassell-Varley型功能性反应的时滞捕食者-食饵系统的周期性问题,利用重合度理论中的Gaines和Mawhin' s延拓定理,建立了该系统至少存在一个正周期解的一组易于验证的充分条件.
研究瞭一類具有脈遲收穫和Hassell-Varley型功能性反應的時滯捕食者-食餌繫統的週期性問題,利用重閤度理論中的Gaines和Mawhin' s延拓定理,建立瞭該繫統至少存在一箇正週期解的一組易于驗證的充分條件.

The periodicty for a delay predator-prey system with impulse harvesting and Hassell-Varley functional response is studied. By using Gaines and Mawhin ' s Continuation Theorem of coincidence degree theory, we establish a set of easily verifiable sufficient conditions under which this system has at least one positive periodic solutions.
