论文是两栏式的，我想在一栏中插入一个图，也就是一个图占用 0.5 倍的纸张宽度，同时需要使用包\bicaption{}{}中的bicaption为一个图创建两个标题。

\usepackage{caption}
\usepackage{multicol}
\usepackage{bicaption}
\begin{document}
xxxx......
\begin{multicols}{2}
\begin{figure}
\includegraphics{figure A}
\end{figure}
\end{multicols}
\end{document}

在这种情况下，该图无法显示在 pdf 文档中。注意，我想在标题处用一栏写一篇论文，在正文处用两栏写一篇论文。正文从标题页开始。例如， 谢谢！

这是不可能的。您不能在multicols环境内部使用浮动。这意味着没有未加星号的figure环境table。您可以使用加星号的版本，尽管它们的行为与外部不同multicols。

如果您查看控制台输出或日志，您将看到一条解释此情况的消息，如软件包文档第 5 页所述。带星号的版本的行为在手册中也有类似的解释。

如果你想要抽象的宽度为两列，那么您只需将twocolumn选项与abstract包结合使用即可。例如：

\documentclass[twocolumn]{article}
\usepackage{kantlipsum}
\usepackage{abstract}
\usepackage{graphicx}
\begin{document}
\twocolumn[
  \begin{onecolabstract}
    As any dedicated reader can clearly see, the Ideal
    of practical reason is a representation of, as far as I
    know, the things in themselves; as I have shown elsewhere, the phenomena should only be used as a canon
    for our understanding. The paralogisms of practical
    reason are what first give rise to the architectonic of
    practical reason. As will easily be shown in the next
    section, reason would thereby be made to contradict,
    in view of these considerations, the Ideal of practical
    reason, yet the manifold depends on the phenomena.
    Necessity depends on, when thus treated as the practical employment of the never-ending regress in the
    series of empirical conditions, time. Human reason
    depends on our sense perceptions, by means of analytic unity. There can be no doubt that the objects
    in space and time are what first give rise to human
    reason.
  \end{onecolabstract}
]
  \kant[2]
  \begin{figure}
    \includegraphics[width=\linewidth]{example-image-a}
    \caption{Example}\label{fig:a}
  \end{figure}

  \kant[3-20]

\end{document}

带有浮动的花式抽象

然后可以使用提供的命令来配置摘要的特定样式，包括缩进abstract。
