In order to discuss the existence of positive solutions to Singular Boundary Value Problems of a Class of Second Order m-point Sublinear Differential Equations,the author continues the research to solve this type of problem by constructing lower and upper solutions and with the maximal theorem and schauder's fixed point principle.A sufficient condition for the existence of C1[0,1] positive solutions is given to Singular Boundary Value Problems of a Class of Second Order m-point Sublinear Differential Equations.
