方程式列表/方程式表

找到后方程表和http://www.latex-community.org/forum/viewtopic.php?f=5&t=428，我开始制作一个方程式列表我的文档。问题在于我们已经有了一份工作草案，它有数百页，包含几十个方程式。

上面的链接描述了如何使用托克洛夫特添加方程式列表，但两者都要求在每个方程后面加上标签，例如\myequations{Display name}。为了避免必须为所有方程添加此标签，我重新定义equation为自动包含我们的\myequations{}命令：

\let\oldequation = \equation
\let\endoldequation = \endequation
\renewenvironment{equation}{
    \begin{oldequation}
}{
    \end{oldequation}
    \myequations{\@currentlabelname}
}

我继续托克洛夫特- 特定代码直接基于上述链接，结尾为：

\usepackage{tocloft}
\newcommand{\listequationsname}{List of Equations}
\newlistof{myequations}{equ}{\listequationsname}

% myequation takes in its display name
\newcommand{\myequations}[1]{

% display name is printed
\addcontentsline{equ}{myequations}{\protect\numberline{\theequation}#1}\par}

然后所有\equations 将自动出现在方程式列表。这很好，但是有一个问题：

每个\equation人显示的名字方程式列表不是其自身的\label（例如“扭矩”）而是它出现的名称\subsection（例如，数十个方程式都具有“直流电机操作”等名称）

有什么想法吗？我可以用什么\@currentlabelname来替换方程式的名称\label？一个简单的方程式如下所示：

\begin{equation}
\tau=F\times r
\label{eq:Torque}
\end{equation}

顺便说一句，我实际上是在 Lyx 中这样做的，但这似乎不是我的问题的根源。事实上，如果有更优雅的 Lyx 解决方案，我愿意倾听。

谢谢！

\section{Brushless Motor Fundamentals}
\subsubsection{DC Motor Operation}
Torque is generated in DC motors from the magnetic force, 
also known as the Lorentz force, which is produced when an
electric current is passed through a coil in a magnetic field. 
This force is given by \ref{eq:Force}.

\begin{equation}
F=q[E+(v\times B)]
\label{eq:Force}
\end{equation}
where F is the force perpendicular to the coil, 
E is the electric field in the coil, 
v is the velocity of the charged particles in the coil, 
and B is the magnetic field. From mechanics, torque is 

\begin{equation}
\tau=F\times r\label{eq:Torque}\end{equation}
If the electrical force in \ref{eq:Force} is ignored, 
and the remaining magnetic force is used in \ref{eq:Torque}, 
with the assumption that v is perpendicular to B, we find that
\begin{equation}
\tau=qvBrsin\theta
\label{eq:Magnetic}\end{equation}

[已修复 - 谢谢麦克伦弗洛] 公式 2.1 - 2.9 在方程式列表但是在方程式编号达到 2.10 之后，最后一位数字（“个位”）与显示名称的开头重叠。

这是 Lev Bishop 代码的修改版本；我使用了字符串包从标签中删除字符串“eq:”：

这是示例的修改版本。主要变化是我\label在方程环境中重新定义：

\documentclass[english]{article}

\let\oldequation = \equation
\let\endoldequation = \endequation
\AtBeginDocument{\let\oldlabel = \label}% \AtBeginDocument because hyperref redefines \label
\newcommand{\mynewlabel}[1]{\myequations{#1}\oldlabel{#1}}
\renewenvironment{equation}{%

% try to make a List of Equations,

答案3

我扩展了以前的答案来定义一个您可以像这样使用的命令：

\noteworthy{a^2 + b^2 = c^2}{Pythagorean theorem}

而且它会自动标记、引用、框出和列出我认为值得注意的方程式。我对结果非常满意。

请注意，红色方块仅突出显示超链接，它们在 pdf 上不可见。

在此处输入图片描述

然后对方程式进行编号、框选、标记文字（与方程式列表相匹配），并贴上标签以便我们引用它。

在此处输入图片描述

最小可行示例：

\documentclass{article}
\usepackage{tocloft}    % for list of equations
\usepackage{ragged2e}   % to undo \centering
\usepackage{hyperref}   % to make references hyperlinks
\usepackage{glossaries} 

% define list of equations
\newcommand{\listequationsname}{\Large{List of Equations}}
\newlistof{myequations}{equ}{\listequationsname}
\newcommand{\myequations}[1]{
   \addcontentsline{equ}{myequations}{\protect\numberline{\theequation}#1}
}
\setlength{\cftmyequationsnumwidth}{2.3em}
\setlength{\cftmyequationsindent}{1.5em}

% command to box, label, reference, and 
% include noteworthy equation in list of equations
\newcommand{\noteworthy}[2]{
\begin{align} \label{#2} \ensuremath{\boxed{#1}} \end{align} 
\myequations{#2} \centering \small \textit{#2} \normalsize \justify }

\begin{document}

\listofmyequations \pagebreak

\noteworthy{P(\bigcup_{n=1}^n A_n) \leq \sum_{n=1}^n P(A_n)}{Boole's inequality}

Where the events $A_n$ are disjoint, then the inequality 
in equation \ref{Boole's inequality} becomes an equality.

\end{document}

答案4

我还无法在常规 LaTeX 中提出一个最小的工作示例。

至于 (2)，尝试设置\cftmyequationsnumwidth为更大的值（参见 tocloft 手册，第 2.3 节）。
