| Abstract: | In this paper,the author generalized the semigroup property of autonomous systems to the cocycle property,and established the existence theorem of the pullback attractor of the non-autonamous systems.At last,the sufficient condition of the existence of the pullback attractor for a non-autonomous system with delays was proved. |
