Latex--有没有办法将编号为一个制表符的等式从右边距移动（向左移动）？

我一直在整理我的论文，有一个小问题让我很难受。 我用下面的代码排版了一个等式

\begin{align}
& R=\frac{P^2}{P+S'} \label{eqn:SCS}\\
&\mbox {where} \quad \mbox R = \mbox {Watershed Runoff} \notag\\
&\hspace{0.63in} \mbox P = \mbox{Rainfall} \notag\\
&\hspace{0.63in} \mbox S' = \mbox{Storage in the watershed $=\frac{1000}{CN}-10$ }\notag
\end{align}

我的输出要求如下： 方程式应从左边距的一个制表符空格开始 方程式编号应在距右边距的一个制表符处结束

使用上面的代码，我让等式从正确的位置开始，而不是编号

任何帮助都将不胜感激

谢谢

我已经尽力了。请注意

fleqn

选项和

minipage

环境。如果您一直需要它，则必须相应地重新定义

align

环境

\usepackage{amsmath}
\begin{document}

Lorem Ipsum is simply dummy text of the printing and typesetting
industry. 

\begin{minipage}{0.8\textwidth}
\begin{align}
& R=\frac{P^2}{P+S'} \label{eqn:SCS}\\
&\mbox {where} \quad \mbox R = \mbox {Watershed Runoff} \notag\\
&\hspace{0.63in} \mbox P = \mbox{Rainfall} \notag\\
&\hspace{0.63in} \mbox S' = \mbox{Storage in the watershed $=\frac{1000}{CN}-10$ }\notag
\end{align}
\end{minipage}

编辑

更优雅和对称的版本：

\documentclass[fleqn]{article}
\usepackage{amsmath}
\makeatletter
\setlength\@mathmargin{0pt}
\makeatother

\begin{document}
\noindent Lorem Ipsum is simply dummy text of the printing and
typesetting
industry. The margins of the quotation environment are indented on the
left and the right. The text is justified at both margins and there is
paragraph indentation. Leaving a blank line between text produces a
new paragraph. 
\begin{quotation}
\begin{align}
& R=\frac{P^2}{P+S'} \label{eqn:SCS}\\
&\mbox {where} \quad \mbox R = \mbox {Watershed Runoff} \notag\\
&\hspace{0.63in} \mbox P = \mbox{Rainfall} \notag\\
&\hspace{0.63in} \mbox S' = \mbox{Storage in the watershed $=\frac{1000}{CN}-10$ }\notag
\end{align}

不管怎样，我一直在使用\setlength{\mathindent}{0.5in}，这使得我的方程从左边缘1in开始。我修改了代码如下在是这样工作的！！！！甜蜜的

\begin{minipage}{5.5in} 
\setlength{\mathindent}{0.0in}
\begin{align} 
& R=\frac{P^2}{P+S'} \label{eqn:SCS}\\ 
&\mbox {where} \quad \mbox R = \mbox {Watershed Runoff} \notag\\ 
&\hspace{0.63in} \mbox P = \mbox{Rainfall} \notag\\ 
&\hspace{0.63in} \mbox S' = \mbox{Storage in the watershed $=\frac{1000}{CN}-10$ }\notag 
\end{align} 
\end{minipage}

你让我开心

brrrr

下面的代码解决了您的问题

\newskip \tabspace \tabspace = 3em % Set tab space
\def\eq{\refstepcounter{equation}(\theequation)}% To insert the next number
{
\let\\\cr \tabskip 0pt
\halign to \hsize{\hskip\tabspace$\displaystyle#$\hfil&#\hfil
   \tabskip 0pt plus 1fil &\hfil#\hskip\tabspace\tabskip 0pt\crcr
%%%% Your code %%%%
R=\frac{P^2}{P+S'}\span\omit&\eq\cr
\hbox{where }&$R$  = Watershed Runoff\cr
             &$P$  = Rainfall\cr
             &$S'$ = Storage in the watershed $=\frac{1000}{CN}-10$\cr
%%%%           %%%%
}
}

看起来像乳胶，你能确认吗？很抱歉搞混了。是的，这是乳胶的问题。谢谢你，汉克斯！！使用minipage将等式1的选项卡空间向右移动！！！令人惊叹的！！但它将等式从左边距移动了两个制表符空间。有什么方法可以将方程移回1个制表符空间吗？不管怎样，我一直在使用\setlength{\mathindent}{0.5in}，这使我的方程从左边距1in开始。我修改了代码如下在是这样工作的！！！！甜蜜的\5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.5.1.1.1.1.1.1.1.1.1.1.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.3.P$}\notag\end{align}\end{minipage}你让我开心！！！！
