英文摘要：

This article studies some qualitative properties of the second order linear operator with periodic conditions, by using the Schauder＇s fixed-point theorem, we obtained the existence of positive periodic solutions of the singular second-order differential system （1.1）. The conclusions in this paper perfect the existed results.
