在双列文档中使用 \centerline 居中文本行时出现问题

Question

以下（重新）定义\resalte可能会满足您的需要：

\newcommand{\resalte}[1]{%
    \begin{quotation}%
    \centering\large\bfseries\sffamily #1%
    \end{quotation}}

嵌入quotation环境用于提供与前后材料之间的垂直分隔，以及左侧和右侧偏移；这应该清楚地表明材料不是一些未编号的节标题。通过使用\bfseriesand\sffamily而不是\textbfand \textsf，宏允许其参数由两个或更多段落组成。（您可能不需要这种通用性，但由于提供它没有成本，因此不妨提供它……）

该\centering命令禁止对其范围内的材料进行连字符连接。如果您确实想允许连字符连接，则应加载包ragged2e并使用其\Centering宏，而不是\centering：

\usepackage{ragged2e}
\newcommand{\resalte}[1]{%
    \begin{quotation}%
    \Centering\large\bfseries\sffamily #1%
    \end{quotation}}

以下是 MWE 适度简化形式的第一页的结果文本块的外观：
