如果这些标题包含数学表达式，我们该如何使用\titlecaps来获得正确的图形和表格的标题？
根据此网站的建议，我在我的 LaTeX 文件中添加了：
%%% set figure captions to use titlecaps
\DeclareCaptionTextFormat{up}{\titlecap{#1}}
\captionsetup[figure]{textformat=up}
\captionsetup[table]{textformat=up}
但我收到了如下标题的编译错误：
\caption{Simulations performed with k-$\omega$ SST and DDES-SST}
因为k-$\omega$标题中的表达。

感谢您的第一个回答，抱歉没有提供完整的 LaTeX 文档！
这是一个更好的例子，我认为\titlecaps和之间存在冲突\bm。
（1）如果对修改相关的行titlecaps进行了注释，则该命令\bm可以正常工作
(2) 如果这些行处于活动状态，则添加时会出现编译错误\bm，如果我没有粗体希腊符号，则一切正常。我希望现在更清楚了。谢谢你的帮助！
