將枚舉列表放在方程式計數器上

我想將某些枚舉列表與我顯示的方程式放在同一個計數器上。誰能建議我如何做到這一點？

接近下面的最小工作範例。

\documentclass{amsart}
\usepackage{enumitem}

\renewcommand{\baselinestretch}{1.3} 
\parskip=5pt  
\parindent=0pt  

\numberwithin{equation}{section}

\begin{document}

\section{My section} 
\subsection{My subsection}

This is an equation that I want to display:
\begin{equation}\label{first}
\mbox{An equation I want to display.}
\end{equation}

I like to be able to refer to \eqref{first}.

Sometimes I like to make normal enumerated lists. 
\begin{enumerate}
\item So interesting. 
\item Also interesting. 
\end{enumerate}

But sometimes, I like to make an enumerated lists that formatted the same way as displayed equations.  
\begin{enumerate}
\item \label{second} First enumerated fact. 
\item \label{third} Second enumerated fact. 
\item \label{fourth} Third enumerated fact.
\end{enumerate} 

And then I want to refer to \eqref{third} the same way that I refer to \eqref{first}. 

\end{document}

我希望能夠對其進行設置，以便第二個清單中的條目被標記為 (1.2)、(1.3)、(1.4)，其樣式與顯示的方程式 (1.1) 相同。

以下端口坎帕指出的答案使用套件\newlist定義的公式enumitem，因此將與其間距命令相容，如下OP的要求。

\documentclass{amsart}
\usepackage{enumitem}

\newlist{eqenum}{enumerate}{1}
\setlist[eqenum]{before=\setcounter{eqenumi}{\value{equation}},after=\setcounter{equation}{\value{eqenumi}},label=(\thesection.\arabic*),ref=\thesection.\arabic*}


\renewcommand{\baselinestretch}{1.3} 
\parskip=5pt  
\parindent=0pt  

\numberwithin{equation}{section}

\begin{document}

\section{My section} 
\subsection{My subsection}

This is an equation that I want to display:
\begin{equation}\label{first}
\mbox{An equation I want to display.}
\end{equation}

I like to be able to refer to \eqref{first}.

Sometimes I like to make normal enumerated lists. 
\begin{enumerate}
\item So interesting. 
\item Also interesting. 
\end{enumerate}

But sometimes, I like to make an enumerated lists that formatted the same way as displayed equations.  
\begin{eqenum}
\item \label{second} First enumerated fact. 
\item \label{third} Second enumerated fact. 
\item \label{fourth} Third enumerated fact.
\end{eqenum} 

And then I want to refer to \eqref{third} the same way that I refer to \eqref{first}. 


\end{document}

筆記:

  • 該語句\newlist{eqenum}{enumerate}{1}指示enumitem建立一個只能在第一層使用的新枚舉清單（不能嵌套它）。
  • before和鍵可用於將計數器複製到用於清單after的計數器，反之亦然。之後我只使用和鍵來設定標籤的外觀。兩者應該分開設置，因為我假設您希望標籤顯示為並希望顯示而不是。enumitemequationeqenumlabelref(1.3)\eqref{third}(1.3)((1.3))
