【Abstract】 In this paper,the authors studies the delay Logistic equation where. Conditions are given to insure that all positive solutions of (E) are asymptotic stability and oscillatory about the positive constant equilibrium.We also obtain conditions for the existence of positive periodic soultions in(E).Our results is the extension and generalize of the result in the paper〔1,2〕.更多还原
