我正在用\documentclass[5p]{elsarticle}它写一篇论文，但我不想在摘要中添加水平线。有人可以指导我吗？
\documentclass[5p]{elsarticle}
\usepackage{lineno,hyperref}
\modulolinenumbers[5]
\journal{Journal of \LaTeX\ Templates}
\begin{document}
\begin{frontmatter}
\title{test title}
\author{ Hariha\corref{cor1}*}
\address{820081,Fukuoka, Japan}
%\fntext[myfootnote]{Since 1880.}
\cortext[mycorrespondingauthor]{Corresponding author}
\ead{[email protected]}
\begin{abstract}

在您的例子中，\MaketitleBox使用 来制作标题。\hrule的定义中有两个命令，\MaketitleBox用于将水平线放在摘要上方和关键字下方。您可以使用包从 的定义中xpatch删除这些命令：\hrule\MaketitleBox
\documentclass[5p]{elsarticle}
\usepackage{xpatch}
\xpatchcmd{\MaketitleBox}{\hrule}{}{}{}% remove first horizontal rule (above abstract)
\xpatchcmd{\MaketitleBox}{\hrule}{}{}{}% remoce second horizonral rule (below keywords)

如果您只想删除摘要上方的规则，请仅使用一个\xpatchcmd。
注意：使用选项preprint代替5p elsarticle将使用\pprintMaketitle代替\MaketitleBox。在这种情况下，补丁将是相同的，但使用\pprintMaketitle代替\MaketitleBox：
\xpatchcmd{\pprintMaketitle}{\hrule}{}{}{}% remove first horizontal rule
\xpatchcmd{\pprintMaketitle}{\hrule}{}{}{}% remoce second horizonral rule
您可以同时使用两者来获得独立于选项的解决方案。
