1. 问题

针对于IEEEtran类模板，其初始模板给定了6个示例作者，如下：

$那如果是5个作者的话，怎么排版呢？$
如果是简单的删掉一个作者，则会显示为以下排版，很不美观：

2. 解决办法

step 1. 在\begin{document} 的上面，\def\BibTeX{…}之间加入以下代码

\makeatletter
\newcommand{\linebreakand}{%\end{@IEEEauthorhalign}\hfill\mbox{}\par\mbox{}\hfill\begin{@IEEEauthorhalign}
}
\makeatother

step 2. 在第3和第4作者之间，去掉\and，并新增\linebreakand

%\and
\linebreakand 

step 3. 重新编译
