因此，我在书中每章附录的图号方面遇到了这个问题。附录的编号简直乱七八糟。我尝试了几个命令来对附录进行不同的编号，但文档的其余部分就是乱七八糟。下面是一张说明和描述问题的图片，以及一个 MWE。
问题
附录图片编号只是数字。我希望第一章附录的图编号为：1.1A、1.2A 1.3A，然后第二章附录的图编号为：2.1A、2.2A。理想情况下，不会弄乱其余图的编号。
最小工作示例（我删除了序言，但我可以将其包括在内）

答案1
下面的代码实现了您想要的图形编号。
此代码有两个重要部分。首先，我添加了一个钩子，用于etoolbox更改图号。其次，我\chapter{..}在后面包含一个命令\begin{appendices}。第二步为附录生成一个章节样式标题，并保存章节计数器的最后一个值，这样您就不会得到章节号为 0 的结果。
\documentclass{book}
\usepackage{appendix}
\usepackage{etoolbox} % <=== add this
\AtBeginEnvironment{appendices}{\renewcommand\thefigure{\arabic{chapter}.\arabic{figure}A}} % <=== add this
\begin{document}
\listoffigures
\chapter{Introduction}
Here we have figures \ref{fig:1} and \ref{fig:2}.
\begin{figure}
\caption{First Figure}\label{fig:1}
\end{figure}
\begin{figure}
\caption{Second Figure}\label{fig:2}
\end{figure}
\begin{appendices}
\chapter{Appendix to Chapter 1} %<=== add this to get title and non-zero chapter counter
Here we have appendix figures \ref{fig:a1} and \ref{fig:a2}.
\begin{figure}
\caption{First Appendix First Figure}\label{fig:a1}
\end{figure}
\begin{figure}
\caption{Second Appendix Second Figure}\label{fig:a2}
\end{figure}
\end{appendices}
\chapter{Conclusion}
\begin{figure}
\caption{Second Chapter Figure}\label{fig:3}
\end{figure}
\begin{appendices}
\chapter{Appendix to Chapter 2}
Here we have appendix figures \ref{fig:a3} and \ref{fig:a4}.
\begin{figure}
\caption{Second Appendix Second Figure}\label{fig:a3}
\end{figure}
\begin{figure}
\caption{Second Appendix Second Figure}\label{fig:a4}
\end{figure}
\end{appendices}
\end{document}
如果您不希望\chapter{..}在附录中包含该命令，以下挂钩仍会将章节号放入图号中：
\makeatletter
\AtBeginEnvironment{appendices}{%
\setcounter{figure}{0}%
\renewcommand\thefigure{\arabic{@ppsavesec}.\arabic{figure}A}%
}
\makeatother
这将重置图形计数器以在附录中重新启动，并使用环境appendices保存了章节号的计数器。如果我将其放入先前的代码中并\chapter{..}从附录中删除命令，则结果是：
正如 David 所指出的，这些include命令不会影响此编号。如果我将这些编辑放入您发布的多文件代码中，则图编号是相同的。因此，使用第二个版本（在后面添加@ppsavesec且没有添加），我从您的文件中获得了以下内容：
\chapter{..}\begin{appendices}
