Abstract: Using the transformation characteristics of vector operator and scalar operator when space is rotated, this paper strictly proves the commutation relations between orbital angular momentum operator and vector operator as well as scalar operator, and constructs several specific scalar operators and vector operators to verify the commutation relations. Finally, the definitions of vector operator and scalar operator are discussed. 

Key words: angular momentum operator, vector operator, scalar operator, commutation relations
