Detection of symmetric functions with partial negated variables based on tabular method

Symmetric functions have many advantages. Introduction of symmetric fuctions with partial negated variables can tremendously increase symmetric function amount,thus making for the range of symmetric function application.The detection of symmetric function is of importance in the research of symmetry .A method for detecting symmetric functions based on tabular method is analyzed.Based upon it, the method of detecting symmetric functions with negation of partial is presented.
