利用比较定理和V泛函方法,证明带时滞和年龄结构的非自治的二食铒一捕食系统的正周期解的存在性和唯一性·
In this paper,by using the comparing theorem and V-function method,we consider a nonautonomous tow-preys one-perdator system with stage stucture and time-delay.We get the sufficient conditions for the uniform persistence and the solutions global sttractivity of this system.And we obtain the existence and uniqueness of a positive periodic solution of this system.
