我在演示中使用了biblatex包及其\footcite{}命令beamer。下面是一个简短的示例：
\documentclass{beamer}
\setbeamertemplate{navigation symbols}{}
% only for this example, otherwise in .bib file
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@article{einstein,
author = "Albert Einstein",
title = "{Zur Elektrodynamik bewegter K{\"o}rper}. ({German})
[{On} the electrodynamics of moving bodies]",
journal = "Annalen der Physik",
volume = "322",
number = "10",
pages = "891--921",
year = "1905",
DOI = "http://dx.doi.org/10.1002/andp.19053221004",
keywords = "physics"
}
@book{dirac,
title={The Principles of Quantum Mechanics},
author={Paul Adrien Maurice Dirac},
isbn={9780198520115},
series={International series of monographs on physics},
year={1981},
publisher={Clarendon Press},
keywords = {physics}
}
\end{filecontents}
\usepackage[style=verbose,citetracker,pagetracker=page,backend=biber]{biblatex}
\addbibresource{\jobname.bib}
\let\footcite\footfullcite
\begin{document}
\begin{frame}
Text text \footcite{einstein}\\
Another text \footcite{einstein}\\
\end{frame}
\begin{frame}
Text text text \footcite{dirac}\\
And something more \footcite{einstein}
\end{frame}
\begin{frame}
\printbibliography
\end{frame}
\end{document}
输出：
但是，我想保留一个数字作为参考。因此所需的输出将是：
我该怎么做？
答案1
使用答案奥黛丽并设置page tracker=page和重新定义\renewcommand\footcite\superfootcite：
\documentclass{beamer}
\setbeamertemplate{navigation symbols}{}
% only for this example, otherwise in .bib file
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
