摘要详细讨论了在粒子数表象和相干态表象中如何简捷地计算谐振子系统坐标算符矩阵元的问题,给出了具体的计算过程并对文献中的相关处理方法和过程进行了评述. The problems of simply and directly computing the matrix elements of coordinate operator for the harmonic oscillator in both the number states and the coherent states representations are studied in detail,the explicit procedures are given and some issues related to the methods and procedures in the literatures are commented.
