我一直在格式化我的论文，一个小问题让我陷入困境。我使用以下代码排版方程

\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}

我的输出要求是这样的： 等式应该从左边距开始一个制表符空间 等式编号应该在距右边距一个制表符空间结束

使用上面的代码，我让等式从正确的位置开始，而不是编号。

任何帮助将不胜感激。

谢谢议员

我能做的最好的。注意fleqn选项和minipage环境。如果您一直需要它，则必须align相应地重新定义环境。

\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}

Lorem Ipsum is simply dummy text of the printing and typesetting
industry. 
\end{document}

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}

没关系，我一直在使用 \setlength{\mathindent}{0.5in} 使我的等式从左边距 1 英寸开始。我修改了代码如下，就像那样工作！！！！甜的...

\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}

你让我今天一整天都感觉很好！！！！

\hspace{.63in}呸呸呸……

以下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
%%%%           %%%%
}
