  1. Next we study the logistic model with both state - dependent delays and continuous delays and feedback control. with the help of coincidence degree theory, some new results for the existence of the postive periodic solution of the system are obtained. also, by constructing suitable lyapunov functional, some sufficient criteria for the uniqueness and globally asymptotic stability of positive periodic solution are established

    第二部分研究同時具有狀態依賴時滯和連續時滯的反饋控制logistic增長模型，利用重合度理論研究其正周期解的存在性問題，得到了該系統周期正解存在的充分性條件；通過構造適當的lyapunov泛函得到保證該系統存在全局穩定周期解的充分性條件。
