Beamer 和减少引用量

Question

如何才能减少 beamer 中一页内脚注引用的大小（本地）？

梅威瑟：

\documentclass[10pt,xcolor={dvipsnames}]{beamer}
\usefonttheme{professionalfonts}
\usepackage{mathtools}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage[english]{babel}


%add  a sample .bib file
\usepackage{filecontents}
\begin{filecontents}{bibexample.bib}
 @article{sigfridsson,
  title = {Four-dimensional flow {MRI} using spiral acquisition},
  volume = {68},
  number = {4},
  journal = {Magnetic Resonance in Medicine},
  author = {Sigfridsson, Andreas and Petersson, Sven and Carlhäll, Carl-Johan 
  and Ebbers, Tino},
  year = {2012},
  pages = {1065--1073}
 }
\end{filecontents}

如果你同意减小普通脚注的大小，可以通过以下方式轻松实现\setbeamerfont{footnote}{size=\tiny}

\documentclass[10pt,xcolor={dvipsnames}]{beamer}
\usefonttheme{professionalfonts}
\usepackage{mathtools}
\usepackage[utf8]{inputenc}
%\usepackage{graphicx}
\usepackage[english]{babel}


%add  a sample .bib file
\usepackage{filecontents}
\begin{filecontents}{bibexample.bib}
 @article{sigfridsson,
  title = {Four-dimensional flow {MRI} using spiral acquisition},
  volume = {68},
  number = {4},
  journal = {Magnetic Resonance in Medicine},
  author = {Sigfridsson, Andreas and Petersson, Sven and Carlhäll, Carl-Johan 
  and Ebbers, Tino},
  year = {2012},
  pages = {1065--1073}
 }
\end{filecontents}
