摘要: 指出本刊近年发表的宇称算符的显式几十年前即已见于文献.对该结果作了几点补充讨论,包括推导的改进、经典极限以及对狄拉克方程的推广.

Abstract: It is pointed out that the explicit formula for the parity operator published in this journal in recent years had been given in the literature several decades ago. Some notes are presented for that formula,including improvement of the derivation,its classical limit,and extension to the Dirac equation.

Key words: parity operator, space inversion operator, explicit formula, classical limit, Dirac equation
