我想让我的“附录”作为补充信息 - 但\renewcommand{\appendixname}{Supplementary Information}我不只是重命名它，还希望它被编号：
补充信息1（部分）
补充信息2（部分）
补充信息 2.1（小节）
补充信息 2.2（小节）
我以为这个编号很简单，\renewcommand{\thesection}{\arabic{section}}但是正如你所看到的，这并没有起到作用。
我非常有限，因为我需要使用这种奇怪的格式/文档类，见下文：

答案1
你必须改变编号后， 不是前，\appendix命令。下面是您的 MWE 的修改版本，我已将您的所有\[和更改\]为常规[和，]以便它可以使用进行编译pdflatex。

我没有改变你之后的奇怪的东西，\end{document}因为那会被忽略pdflatex。
