平均能量损失

Question

我想制作带有的beamer幻灯片biblatex，并将引文的字体大小设置为，\autocite{}同时\tiny保持引文的字体大小为\textcite默认值（\normalsize）。

目前，我使用\renewcommand*{\citesetup}{\tiny}但此命令将所有引用的字体大小设置为\tiny。

有什么方法可以修改beamer或biblatex设置来实现这一点吗？

请注意，但我不想通过手写输入来获得这种效果\tiny \autocite{...} \normalsize。我正在寻找更系统的方法。

不幸的是，当\citesetup使用时，我们还无法访问定界符上下文来分支我们所处的确切引用命令。一个直接但稍微繁琐的解决方案是使用包装器命令来\DeclareCiteCommand包装\parencite（这就是\autocite这里的情况）不仅在括号中，而且在小括号中。

原始定义可以在apa.cbx（版本 8.5 中第 484-503 行）。我们只定义一个新的\mkbibtinyparens并使用它来代替\mkbibparens。

\documentclass{beamer}

\usepackage[%
  style = apa6,
  sortcites = true, 
  backend = biber]{biblatex}
\bibliography{biblatex-examples.bib}

\newcommand*{\mkbibtinyparens}[1]{{\tiny\mkbibparens{#1}}}

\DeclareCiteCommand{\parencite}[\mkbibtinyparens]
  {\usebibmacro{cite:init}%
   \usebibmacro{prenote}}
  {\usebibmacro{citeindex}%
   \usebibmacro{cite}%
   \usebibmacro{cite:post}}
  {}
  {\usebibmacro{postnote}}

\DeclareMultiCiteCommand{\parencites}[\mkbibtinyparens]{\parencite}
  {\setunit{\multicitedelim}}

\DeclareCiteCommand*{\parencite}[\mkbibtinyparens]
  {\usebibmacro{cite:init}%
   \usebibmacro{prenote}}
  {\usebibmacro{citeindex}%
   \usebibmacro{citeyear}%
   \usebibmacro{cite:post}}
  {}
