如何防止主标题被包裹在图形中？

我正在使用 LaTeX 写一篇论文，并使用 subfig 包来排列图像。我的问题是，当我使用 2 x 3 图像和占据 2 列的 subfloat 时，主标题会被换行。我也尝试过使用它\captionsetup来设置宽度、格式……但不起作用。

代码如下：

\begin{figure}[t]   
\subfloat[8 images]{{\includegraphics[width=5.5cm]{screenshots/Comparison/8_jump} }}%
\subfloat[16 images]{{\includegraphics[width=5.5cm]{screenshots/Comparison/16_jump} }}%    
\subfloat[32 images]{{\includegraphics[width=5.5cm]{screenshots/Comparison/32_jump} }}%
\hfill    
\subfloat[8 times]{{\includegraphics[width=5.5cm]{screenshots/Comparison/8_ours_jump} }}%
\subfloat[16 times]{{\includegraphics[width=5.5cm]{screenshots/Comparison/16_ours_jump} }}%    
\subfloat[32 times]{{\includegraphics[width=5.5cm]{screenshots/Comparison/32_ours_jump} }}% 

\caption{AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA long caption which occupies two column, but it is wrapped into one column.}%

\label{fig:Comparison}%
\end{figure}

如何输入占据两列的主标题？

我从您的描述中推断（虽然没有明确说明），您的文档使用双列格式。此外，您希望生成一个横跨两个文本列的图形。如果是这样，您应该使用环境figure*而不是figure环境；前者设置为横跨两列，因此其标题也将能够横跨图形的整个宽度。

我还建议您不要为子图设置绝对宽度，而是使用相对宽度。这样做可以更直接地高效填充可用空间，而无需进行大量的反复试验。

下列屏幕截图中三条边周围的细线是由showframe包插入的；它们仅仅是为了说明文本块的边缘。

在此处输入图片描述

\documentclass[twocolumn]{article}
\usepackage{subfig}         % for "\subfloat" macros
\usepackage[demo]{graphicx} % remove "demo" option in your real document
\usepackage{showframe}      % just to illustrate borders of text block
\usepackage{lipsum}         % package that provides filler text

\begin{document}
\lipsum[1-2] % filler text

\begin{figure*}[t!]
\subfloat[8 images]{\includegraphics[width=0.32\textwidth]{screenshots/Comparison/8_jump}}\hspace*{\fill}
\subfloat[16 images]{\includegraphics[width=0.32\textwidth]{screenshots/Comparison/16_jump}}\hspace*{\fill}
\subfloat[32 images]{\includegraphics[width=0.32\textwidth]{screenshots/Comparison/32_jump}}

\subfloat[8 times]{\includegraphics[width=0.32\textwidth]{screenshots/Comparison/8_ours_jump}}\hspace*{\fill}
\subfloat[16 times]{\includegraphics[width=0.32\textwidth]{screenshots/Comparison/16_ours_jump}}\hspace*{\fill}   
\subfloat[32 times]{\includegraphics[width=0.32\textwidth]{screenshots/Comparison/32_ours_jump}} 

\caption{Six subfigures with a very long caption which now occupies both columns. Observe that the caption is no longer confined to the first, i.e., left-hand, column.}

\label{fig:Comparison}
\end{figure*}

\lipsum[3-9] % more filler text
\end{document}
