Boondox 书法数学字体和 Arev 数学字体的大写字母和小写字母的高度不一样。
调整答案使用 XeTeX/fontspec 伪造小型大写字母？，我过去常常scalebox定义和校正高度，使它们与大写字母和小写字母相匹配。请参阅下文包含高度校正的新宏的实现以及排除校正的\mathcalbd基本宏。\mathcalbdnocorr
出现了两个问题：
- 不支持下标和上标
- 与包有冲突

Two problems with the \verb+\mathcalbd+ macro:
\begin{enumerate}
\item \verb+\mathcalbd{A_a}+ does not work while
\verb+\mathcalbdnocorr{A_a}+ does ($\mathcalbdnocorr{A_a}$). Same is
true for superscripts.
\item \verb+\boldsymbol{\mathcalbd{A}}+ ($\boldsymbol{\mathcalbd{A}}$)
does not work if package \texttt{bm} is loaded
\end{enumerate}

您可以使用两种字体系列，分别为大写和小写设置不同的缩放比例。
