我需要在中插入行号elsarticle，因此我添加了：
\usepackage{lineno} % add
\linenumbers
在文章序言中。
然而，我注意到摘要的一部分没有编号：
您能建议我应该改变什么吗？
我的文档如下所示：
\documentclass[review]{elsarticle}
\usepackage[hyphens]{url}
\usepackage{lineno} % add
\linenumbers
\providecommand{\tightlist}{%
\setlength{\itemsep}{0pt}\setlength{\parskip}{0pt}}
%%% Removing 'preprint sent to Elsevier' text, because it is causing troubles
\makeatletter
\def\ps@pprintTitle{%
\let\@oddhead\@empty
\let\@evenhead\@empty
\def\@oddfoot{\reset@font\hfil\thepage\hfil}
\let\@evenfoot\@oddfoot
}
\makeatother

来自lineno文档：
\linenumbers仅在段落结束时才生效。如果您\linenumbers只用于单个段落，这一点很重要。这将不起作用
为了获得正确的行号，你可以明确结束段落
\documentclass[review]{elsarticle}
\usepackage{lineno}
\begin{document}
\linenumbers
\begin{frontmatter}
\title{Title}
\author{Me}
\address{Here}
\begin{abstract}
First line of abstract. This part of abstract is numbered as well
as other sections. Only the second part of abstract is not numbered.
The second part of the abstract. Lorem ipsum dolor sit et amet.
Some text.\par% or add an empty line after this one
\end{abstract}
\end{frontmatter}
\section{Introduction}\label{introduction}
Some text
\end{document}
或使用linenumbers环境
\documentclass[review]{elsarticle}
\usepackage{lineno}
\begin{document}
\linenumbers
\begin{frontmatter}
\title{Title}
\author{Me}
\address{Here}
\begin{abstract}
\begin{linenumbers}
First line of abstract. This part of abstract is numbered as well
as other sections. Only the second part of abstract is not numbered.
The second part of the abstract. Lorem ipsum dolor sit et amet.
Some text.
\end{linenumbers}
\end{abstract}
\end{frontmatter}
\section{Introduction}\label{introduction}
Some text
\end{document}
