In this paper,the retarded functional differential equation are considered, We obtain four existence theorems of periodc solutions of it, The application of these theorems are convenient and efficient and the theorem of this paper is better than the well-known Yoshizawa's periodic solution theorem.A feedback system is discussed in detail and a sufficient condition of guaranteeing the existence of an ω-Periodic motion of the system is got by applying these theorems in this paper.
