从普通矢量谈到右矢量和算符的表象

COMMENTS ON THE REPRESENTATIONS OF KET VECTORS AND LINEAR OPERATORS

本文通过对微观体系运功状态的右矢量与普通矢量类比,阐明右矢量可以用列矩阵来表象。然后比较两个不同算符的展开形式,清楚地看到算符可以用方阵表象。

In this paper,we discussed the representation of the general vector A.Then we compare the ket vector |p〉with the vector A.The representations of the ket and bra vectors are explained clear.The expansions of two linear operators were compared. It is understood that the representaton of the operator is the square matrix.
