This paper studies the existence of positive solutions for second order nonlinear ordinary differential system. Under the suitable conditions, by transforming the boundary value problem into the corresponding fixed-point problem of a completely continuous operator, the existence is obtained in the paper for second order superlin?ear singular semipositone differential system via the fixed point theorem concerning cone compression and expan?sion.
