摘　　要：利用相干态表象推导出了将算符反正规排序转化为正规排序的基本算符恒等式,并给出了把一般算符转化为反正规排序的基本方法.在此基础上,推导出了压缩算符的反正规乘积形式及其Wigner函数.This paper uses the coherent state representation to derive the basic operator identity for converting anti-normal sorting into normal sorting,and provides the basic method for converting general operators into anti-normal sorting.On this basis,the anti-normal product form of the compression operator and its Wigner function are derived.

关 键 词：算符恒等式 压缩算符 反正规乘积 WIGNER函数
