| 摘 要： | 本文以能量和波函数的各级微扰近似的基态展开式为基础,推导出任一力学量的矩阵元F_(mn)的各级微扰近似表示式。并且指出只要构成能量展式的级数收敛很快,满足能够应用微扰的条件,那么对于任一力学量F的微扰计算,只要计算矩阵元F_(mn)的前二级近似就已足够精确。

| Abstract: | Based on the perturbation approximations of wave function and energy, this paper derives the expressions of perturbation approximation of the matrix
elements Fmn of any mechanical quantity operator F in quantum mechanics. In addition,if only the convergence of series expansion of energy is rapid enough that the perturbation condition can be used, it is exact enough just to calculate the perturbation approximations of the first two orders of matrix element Fmn. |
