摘　　要：通过积分计算讨论了矩阵元<p'︱x︱p''>的结果,从不同的方面证明了所得到的两个结果的正确性和一致性,提出在坐标和动量表象中进行矩阵元的计算时应遵循向左作用的规则。虽然这与通常的本征方程的作用规则相反,但遵循向左作用的规则即可保证结果的正确性。First the possible resuhs of matrix element were got by calculating its integration, then the correctness and consistency of the two results were proved from different aspects. In the end, the action rule to the left was proposed, which was to be followed during the calculation of matrix element in coordinate and momentum representations although it was different from the action rule of the eigen equation.
