文档的其余部分是两列,只有附录需要一列才能适合方程式。这是代码,任何帮助都非常感谢!

答案1
以下是我所说的使用几何学包裹:
\documentclass[a4paper,twocolumn]{article}
\usepackage[T1]{fontenc}
\usepackage[pass]{geometry}
\usepackage{lipsum}
\title{My Article}
\author{My Name}
\begin{document}
\maketitle
\tableofcontents
\section{Foo}
\lipsum[1-4]
\section{Bar}
\lipsum[5-8]
\section{Baz}
\lipsum[9-16]
\newgeometry{onecolumn,textwidth=345pt} % adjust value if needed
\section{This is in one-column mode}
\lipsum[17-20]
\end{document}
在命令中,如果您愿意,\newgeometry
还可以设置;但大多数情况下,默认值(自动符合/设置)即可。hmarginratio
oneside
twoside
