Bell nonlocality and Einstein-Podolsky-Rosen(EPR)steering are every important quantum correlations of a composite quantum system.Bell nonlocality of a bipartite state is a quantum correlation demonstrated by some local quantum measurements,while EPR steering is another form of quantum correlations,observed by Schrodinger in the context of famous EPR paradox.In this paper,we give some remarks on Bell nonlocality and EPR steering of bipartite states,including mathematical definitions and characterizations of these two quantum correlations,the convexity and closedness of the set of all Bell local states and the set of all EPR unsteerable states.We also derive a EPR-steering criteria,with which the EPR steerability of the maximally entangled states are checked.
