Latex中怎么去掉proof后的小方框

去掉指定证明模块中的小方框。在\begin{proof}之后加上\renewcommand{\qedsymbol}{}即可。

\documentclass{article}  
\usepackage{amsthm}  
\begin{document}  
\begin{proof}  
This has the QED symbol.  
\end{proof}  
\begin{proof}\renewcommand{\qedsymbol}{}
This hasn't.  
\end{proof}  
\begin{proof}  
And this has it again.  
\end{proof}  
\end{document}  
           

去掉整个论文的中证明后面的小方框，在论文开始部分加入\renewcommand{\qedsymbol}{}

\documentclass{article}  
\usepackage{amsthm}  
\begin{document}  
\renewcommand{\qedsymbol}{}
\begin{proof}  
This has the QED symbol.  
\end{proof}  
\begin{proof}
This hasn't.  
\end{proof}  
\begin{proof}  
And this has it again.  
\end{proof}  
\end{document}
