我在下面链接了两个问题，因为我使用它们的解决方案来编号我的方程式并生成我的方程式列表。
- 关于编号方程的问题：方程式数量：1、1a、1b
- 生成方程式列表：方程式表，类似图表列表
尽管它们可能没有直接相关性，但我提到我使用它们是因为我不确定这是否会扰乱可能的解决方案。
在我的 MWE 之下。到目前为止，它运行良好（附图）。
但是我希望我的方程的“列表名称”（在本例中为\myequations{PDE of the diffsion process}）可以作为一种变量使用，这样我就可以将其称为“由...\XXX给出”，其中\XXX一个命令为我提供\myequations{...}我所引用的方程的名称（）（例如\tag{\ref{eq:litdiff}}）。
我希望我的等式是清楚的，如果不清楚，请告知。

The PDE of the diffsion process is given by
\begin{subequations}\label{eq:litdiff}
\begin{equation}
\pdv{}{t} (\widetilde{c}_{\subs}(r,z,t)+c_{\subs,0})=\frac{D_{\subs}}{r^{2}}\pdv{}{r} \left(r^{2}\frac{\partial (\widetilde{c}_{\subs}(r,z,t)+c_{\subs,0})}{\partial r}\right)
\tag{\ref{eq:litdiff}}
\end{equation}
\myequations{PDE of the diffsion process}
\noindent The boundary conditions of Eq.~\eqref{eq:litdiff} are given by
\begin{align}
D_{\subs}\pdv{}{r} \widetilde{c}_{\subs}(0,z,t) &= 0 \label{eq:diffusionpartialdiff_boundaries0}\\
D_{\subs}\pdv{}{r} \widetilde{c}_{\subs}(R_{\subs},z,t) &= -j(z,t)\label{eq:diffusionpartialdiff_boundariesRs}
\end{align}
and the initial condition is given by
\begin{equation}
\widetilde{c}_{\subs}(r,z,0) = 0 \quad r\in [0;R_{\subs}].

这是将其合并\mylabel到 中的一种方法\myequation。\makeatletter...\makeatother由于\protected@write和中使用了 @ 符号，因此需要\@auxout。

您可以将其包含到您的 \myequation 命令中。
\documentclass[12pt]{article}
\makeatletter
\newcommand{\mylabel}[2]% #1 = label name, #2 = text for \ref
{\protected@write\@auxout{}{\string\newlabel{#1}{{#2}{\thepage}}}}
\makeatother
\begin{document}
\mylabel{eq:name}{almost anything}
You can use this to reference \ref{eq:name}.
\end{document}
