Abstract：By extendig the equivalence relation to binary relation on Pawlak rough set approximation space,we obtain the generalized approximation space A=(U,R),and define its lower and upper approxi-mation.Also,we discuss the characterization of serial ,reflexive,symmetric and transitive binary special re-lationship and approximate operator and find the relations of properties between the two .
