关于共轭算子一个性质证明的纠误

Correction on the Proof of a Property for Adjoint Operator

指出了夏道行所编"实变函数与泛函分析"一书第6章第4节共轭算子的性质:(A*)*=A证明过程的错误,并给出了详细的证明.

This paper points out a mistake about the proof an adjoint operator＇s property（A＊）＊=A,which exists in the Part 4 of Chapter 6 of The Real Variable Function and Functional Analysis compiled by Daoxing Xia,and gives the detailed proof.
