Beamer/LuaLaTeX：如何正确排版数学符号？

Question

以下代码的输出\tilde{T}在第二个等式中排版错误；如何修复？

\RequirePackage{luatex85}
\documentclass[professionalfonts]{beamer}
\usetheme{metropolis}
\usefonttheme[onlymath]{serif}
\usepackage{amsmath,mathtools,bm}
\setbeamercolor{normal text}{fg=black}
\newcommand\vm[1]{\bm{#1}}
\newcommand\pbm[1]{\left(\mathbf{#1}\right)}

\begin{document}

\begin{frame}

\begin{align}
    \vm{\Phi}_{,\gamma}^T & = \vm{P}_{,\gamma}^T\pbm{x}\,\vm{A}^{-1}\,\vm{B} = \left\{ \begin{array}{c c c c}
    \phi_1 & \phi_2 & \cdots & \phi_n 
    \end{array} \right\}_{\left(1 \times n\right)},\\
    %
    \mathbf{\tilde{T}_s} & =%
    \left\{%
    \begin{array}{ccccc}
    T_1 & T_2 & \cdots & T_n & \bm{0}_{\left( 1 \times m \right)} 
    \end{array}%
    \right\}^T
\end{align}

\end{frame}

\end{document}

Answer 1

您应该\mathbf{\tilde{T}_s}用替换\widetilde{\mathbf{T}}_{\mathbf{s}}。 （请注意，T和s字符设置为粗体，而“波浪号”变音符号则没有。）

\RequirePackage{luatex85}
\documentclass[professionalfonts]{beamer}
\usetheme{metropolis}
\usefonttheme[onlymath]{serif}
\usepackage{mathtools,bm}
\setbeamercolor{normal text}{fg=black}
\newcommand\vm[1]{\bm{#1}}
\newcommand\pbm[1]{\left(\mathbf{#1}\right)}

\begin{document}
\begin{frame}
$\mathbf{\tilde{T}_s}$ vs.\ $\widetilde{\mathbf{T}}_s$
\end{frame}
\end{document}
