无法更改 tcolorbox 中的默认数学字体大小

Question

这里我有一个 MWE，显示数学模式下文本的字体大小不受我使用更改默认大小的影响，\DeclareMathSizes但在我的之外时会更改tcolorbox。我该怎么做才能解决这个问题？

\documentclass{beamer}
\usepackage[most]{tcolorbox}

\newtcboxfit{\myboxSlideBody}{
                    fit basedim=14pt,
                    % standard jigsaw,
                    % opacityback=0,
                    % opacityframe=0,
                    colframe=green,
                    height=5.9cm,
                    width=10cm,
                    valign=top,
                    halign=left,
                    right=0pt,
                    left=0pt,
                    top=0pt,
                    bottom=0pt
                    }

\newcommand{\framebody}[1]{
\vskip-0.25cm
\hspace*{-0.56cm}
\begin{minipage}{1.1\textwidth}
\myboxSlideBody{#1}\par%
\end{minipage}
}

\makeatletter
\DeclareMathSizes{\f@size}{18}{14}{12}
\makeatother


\begin{document}

\begin{frame}{Frame Title}
$\vec{G} = \left\langle x,y,z\right\rangle$
\vskip0.5cm
\framebody{
$\vec{G} = \left\langle x,y,z\right\rangle$
}
    
\end{frame}

\end{document}

Answer 1

在序言中\f@size，10.95您为该文本大小声明了数学字体，但是\f@size在14您的框架中，因此获得标准设置。
