像研究论文一样，我想在正文之间添加“正在发表的文章”之类的内容。如何实现？
答案1
也许这有帮助：
\documentclass[11pt]{article}
\title{This will be a great article}
\author{The author}
\usepackage{draftwatermark} % one of the packages that can be used for watermarks, as shown below
\begin{document}
\maketitle
\SetWatermarkText{Article in Press} % Text to be printed across the page
\SetWatermarkScale{3} % Size of the watermark text
% further options include
% \SetWatermarkColor[rgb]{0,0,1} % choose color of watermark, default is 80% grey
%
% For more information see https://www.ctan.org/pkg/draftwatermark
%
\abstract{An article that has not been printed yet.}
\section{Introduction}
Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor
incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis

\end{document}

另一个选择是使用background包裹：
\documentclass{article}
\usepackage[scale=5,opacity=0.75,color=gray]{background}
\backgroundsetup{contents={\sffamily Article in Press}}
\usepackage{lipsum}% just to generate filler text
\begin{document}
\lipsum[1-20]
\end{document}
生成的文档：
如果你想叠加图像，这里有一个使用 TikZ 的选项，xwatermark：
\documentclass{article}
\usepackage[printwatermark]{xwatermark}
\usepackage{xcolor}
\usepackage{tikz}
\usepackage{graphicx}
\usepackage{lipsum}
\newsavebox\mybox
\savebox\mybox{\tikz\node[opacity=0.75,scale=6,text=gray,font=\sffamily]{Article in Press};}
\newwatermark*[allpages,angle=60,xpos=0,ypos=0]{\usebox\mybox}
\begin{document}
\lipsum[1-2]
\begin{figure}[!ht]
\centering
\includegraphics[width=3cm]{example-image-a}
\end{figure}
\lipsum[1-15]
\end{document}
结果：
