我正在撰写我的硕士论文，在乳胶的设置方面遇到了一些问题。
我想要将每个方程制成表格（hspace）。
我不希望它从左侧开始或者居中。
我能否以某种方式在序言中全局地指示方程的起始位置？
答案1
只需改变值\mathindent：
\documentclass{book}
\usepackage[fleqn]{amsmath}
\usepackage[showframe]{geometry}
\setlength\mathindent{4pc}
\begin{document}
\noindent This is for test
\begin{equation}
a+b=c
\end{equation}
\setlength\mathindent{12pc}
\begin{equation}
d = e + f
\end{equation}
\setlength\mathindent{0pc}
\begin{equation}
a + b + d =c + e + f
\end{equation}
\end{document}
添加：
我已经简化了您的代码preamble.tex，因为有许多包需要多重加载：
\documentclass[article,12pt, onecolumn, twoside, titlepage, openright]{memoir}
%documentclass{report} - For longer reports containing several chapters, small books, thesis, ...
