小页面中的并排标题太长，不要换到第二行

Question

我正在根据风格指南撰写一些论文集这里。我有两张图片，我想将它们并排放在文章中，但当我这样做时，标题不会换行，而是相互重叠并超出页面的两侧，如下图所示。我知道这是样式指南的问题，因为当我将 MWE 更改为时，标题换行\documentclass{article}正确。

有人能告诉我为什么会发生这种情况以及如何解决吗？

\documentclass[aPhyssubmission, Phys]{SciPost}
\usepackage{graphicx}
\usepackage{subcaption}
\usepackage{float}

\begin{document}

\begin{figure}[H]
    \begin{minipage}[t]{0.4\textwidth}
        \includegraphics[scale=0.6]{example-image-a} 
        \label{fig:X17Exclusion}
        \centering
        \caption{My long caption includes some useless test text and is poorly formatted.}
    \end{minipage}
    \begin{minipage}[t]{0.4\textwidth}
        \includegraphics[scale=0.6]{example-image-a} 
        \label{fig:PADMEX17Scan}
        \caption{My long caption includes some useless test text and is poorly formatted and goes over multiple lines.}
    \end{minipage}
\end{figure}

\end{document}

Answer 1

SciPost（我在网上找到了一份文件类的副本https://git.scipost.org/scipost/SciPost_LaTeX_Templates_Submission。）

文档SciPost类会自动加载其他包caption，并带有（至少对我来说）有点令人惊讶的选项

width=.90\textwidth

这就是您所遇到的与字幕相关的混乱的原因。

minipage解决办法？假设环境内部环境的宽度figure设置为0.45\textwidth，你可以发出指令

\captionsetup{width=0.45\textwidth}

之后立马\begin{figure}。

\documentclass[aPhyssubmission, Phys]{SciPost}
% This document class loads several packages automatically, including 'caption', 'graphicx', and 'hyperref' 
\hypersetup{colorlinks,allcolors=blue} % optional

\begin{document}

\begin{figure}[ht]
\captionsetup{width=0.45\textwidth} % same as width of minipage environments
    \begin{minipage}[t]{0.45\textwidth}
      \includegraphics[width=\linewidth]{example-image-a} 
      \caption{This long caption includes some useless test text and is poorly formatted.}
      \label{fig:X17Exclusion} % note: \label is placed after \caption
    \end{minipage}%
    \hfill % maximize separation between the minipages
    \begin{minipage}[t]{0.45\textwidth}
      \includegraphics[width=\linewidth]{example-image-b} 
      \caption{This long caption includes some useless test text, is poorly formatted, and goes over multiple lines.}
      \label{fig:PADMEX17Scan} % note: \label is placed after \caption
    \end{minipage}
\end{figure}
