摘　　要：利用相干态和正规乘积对谐振子任意次幂坐标算符^Xl矩阵元进行了讨论,导出了计算^Xl矩阵元的一般公式,为处理谐振子的微扰问题提供了一种新的方法。Matrix element of coordinate operator ~l of harmonic oscillator is discussed by using coherent state and normal product.The general formula calculating matrix element of ~l is obtained.That is the same to that of the document [1-2]. This offers a new method for dealing with the perturbation of harmonic oscillator.

关 键 词：谐振子 坐标算符 矩阵元 相干态 正规乘积
