我正在使用以下软件包：hyperref 和 answers。我想将定理的数量与其证明联系起来，或将练习的数量与其解决方案联系起来，或将问题的数量与其提示联系起来，等等。这是我到目前为止从这里和那里的片段中得到的结果（它几乎满足了我的要求，除了问题的数量被打印了两次）：
\documentclass{article}
\usepackage[english]{babel}
\usepackage{hyperref}
\usepackage{enumitem}
\usepackage{answers}
\usepackage{color}
\hypersetup{
colorlinks,
citecolor=black,

}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{blindtext}
\newtheorem{Thm}{Theorem}[section]
%Exercises and solutions
\newtheorem{Ex}[Thm]{\hyperlink{\theEx}{Exercise \theEx}}
\Newassociation{Sol}{Solution}{Answ}
\makeatletter % To adjust the final position of target
\newcommand{\adj}[1]{\Hy@raisedlink{\hypertarget{#1}{}}}
\makeatother
\renewenvironment{Solution}[1]
{\par\bigskip\noindent{\bfseries \adj{#1}{Answer #1}} \par\bigskip}
\begin{document}
\section{This is a section}
\blindtext
\begin{Thm}
This is a theorem
\end{Thm}
\subsection{Exercises}
\Opensolutionfile{Answ}
\begin{Ex}
This is the first exercise
\begin{Sol}
This is the solution to the first exercise
\end{Sol}
\end{Ex}
\begin{Ex}
This is the second exercise
\begin{Sol}
This is the solution to the second exercise
\end{Sol}
\end{Ex}
\Closesolutionfile{Answ}
\Blindtext
\input{Answ}
\end{document}
答案1
可以重新定义plain样式或定义新样式
\newtheoremstyle{plain}%
{}{}%
{\itshape}{}%
{\bfseries}{.}%
{ }%
{\hyperlink{\theEx}{\thmname{#1}\thmnumber{ #2}}\thmnote{ (#3)}}
