amsart 文档中有多个摘要

Question

据我所知，一篇论文只能写一个摘要。阿姆萨特文档。是否可以使用 amsart 模板编写多个摘要？

Answer 1

如果您对第一个摘要采用文档的主要语言感到满意，则可以定义一个\newabstract命令，以您想要排版第二个（第三个，...）摘要的语言作为参数。

\documentclass[a4paper]{amsart}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[italian,english]{babel}

\usepackage{lipsum}

\newcommand{\newabstract}[1]{%
  \par\bigskip
  \csname otherlanguage*\endcsname{#1}%
  \csname captions#1\endcsname
  \item[\hskip\labelsep\scshape\abstractname.]
}

\begin{document}

\title{A title}
\author{A. Uthor}

\begin{abstract}
This is the abstract in the main language. \lipsum[2]

\newabstract{italian}
E questo è il sunto in un'altra lingua. \lipsum[3]
\end{abstract}

\maketitle

\end{document}

我使用\otherlanguage*和\captions{...}以避免\selectlanguage在文件中写入不需要的注释之类的命令.aux。

该版本允许以任何顺序给出摘要，并重新定义环境以接受语言作为可选参数（默认为发布`\begin{abstract} 时的当前语言，通常是主文档的语言）。

\documentclass[a4paper]{amsart}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[italian,english]{babel}

\usepackage{lipsum}

\makeatletter
\renewenvironment{abstract}[1][\languagename]{%
  \ifx\maketitle\relax
    \ClassWarning{\@classname}{Abstract should precede
      \protect\maketitle\space in AMS document classes; reported}%
  \fi
  \global\setbox\abstractbox=\vtop \bgroup
    \unvbox\abstractbox % add the previous abstracts
    \medskip
    \normalfont\Small
    \list{}{\labelwidth\z@

    }%
    % change the current language
    \csname otherlanguage*\endcsname{#1}\csname captions#1\endcsname
