这通常被称为\marginpar
。
\documentclass{article}
\usepackage{newpxtext}
\begin{document}
In most collections, the same concept may be referred to using different
words. This issue, known as \marginpar{\textsc{synonymy}}\emph{synonymy}, has an impact on the recall of most
information retrieval systems. For example, you would want a search for
\textsf{aircraft} to match \textsf{plane} (but only for references to an \emph{airplane}, not a woodworking
plane), and for a search on \textsf{thermodynamics} to match references to \textsf{heat} in
appropriate discussions.
\end{document}
\marginpar[<left>]{<right>}
可以通过处于模式时在左侧或右侧定位twoside
。您还可以考虑使用marginnote
包裹,取决于使用深度。
