如何在 elsarticle 的摘要中添加关键词？

Question

我对 LaTeX 还很陌生。我正在用 Tex Studio 准备一篇期刊文章。我也下载了 TexLive 并正在使用它。问题是\begin{keywords)返回unrecognized command。

\end{abstract}
\begin{keywords}
\end{keywords}
\end{frontmatter}
\maketitle
\date{today}
\newpage

我该如何解决这个问题？谢谢。

Answer 1

您可以继续使用keyword（不是keywords）环境：

\documentclass[5p,number,preprint,times]{elsarticle}
% include here any package you may need
\begin{document}

\begin{abstract}
My wonderful abstract
\end{abstract}

\begin{keyword}Something \sep%
    Something else
\end{keyword}

\begin{frontmatter}
\title{The title of my beautiful article}

\author[unilu]{My name\corref{cor1}}
\ead{[email protected]}

\cortext[cor1]{Corresponding author. Tel.: [phone].}
\address[myuni]{University of Somewhere}

\date{Received: date / Accepted: date}
% The correct dates will be entered by the editor
\end{frontmatter}


% == == == == == == == == == == == == == == ==
% Introduction
% == == == == == == == == == == == == == == ==
\section{Introduction}
\label{sec:intro}

\end{document}

结果：

Answer 2

问题解决了！非常感谢。我通过进入宏菜单来做到这一点，我在其中创建并保存了keyword环境宏（在我的情况下保存为“elskeyword”）。其余部分由下面的命令处理

\let\elskeyword\keyword
\let\endelskeyword\endkeyword
\usepackage{program}
...
\begin{frontmatter}
\title{Title of my report}
\begin{elskeyword}
  keyword1 \sep keyword2 \sep keyword3 \sep keyword4
\end{elskeyword}
\end{frontmatter}
