可以将定理数存储在变量中吗？
我使用 \newtheorem 并且编号是自动完成的。有时在文中我会用这个数字来引用定理。我希望有一个等于该数字的变量，因此如果定理编号发生变化，引用也会发生变化。
I use \newtheorem and the numbering is done automatically. Sometimes in the text I'll refer to a theorem by this number. I'd like to have a variable equal to this number, so if the theorem number changes, the references will change also.

是的，它通过通常的
\label/\ref机制工作：（您需要运行两次 LaTeX 才能确定数字，您将收到一条消息关于更改的引用。）标签命令“附加”某些内容，例如节标题、标题、枚举项以及定理和朋友。
还有一些扩展可以自动区分节与子节或图形，为此，请参阅 hyperref 的
\autoref或 smartef 包，但此时不必担心。Yes, it works through the usual
\label/\ref-mechanism:(You'll need two runs of LaTeX for the number to settle, you'll get a message about changed references.) Label commands "tack onto" certain things like section headers, captions, items of enumerations and, indeed, theorems and friends.
There are also extensions that can automatically distinguish sections from subsections or figures, for that, see hyperref's
\autorefor the cleveref package, but don't worry about it at this point.您需要在
\begin{yourtheorem} \end{yourtheorem}之间放置一个\label并使用\ref照常引用它。您可以查看此链接以获取有关更广泛上下文的说明定理
You need to put a
\labelbetween the\begin{yourtheorem} \end{yourtheorem}and use\refto refer to it as usual.You can check this link for explanations with some broader context about theorems
