【Abstract】 In this paper,a nonautonomous SIS-Infections diseases model with Logistic species growth is considered,where all parameters are time-dependent.It is proved that the system can be made persistent under some condilions.Conditions are established for the existence and the stability of the positive periodic solutions with respect to the corresponding periodic system.更多还原
