Abstract: By using the over-completeness of coherent state and the technique of integration within an ordered product of operators，we derive some new normal ordering forms of quantum operators. Compared with other methods， this method is easier and clearer in theory and application.
Key words: coherent state, normal ordering of quantum operators, technique of integration within an ordered product of operators
