主题Madrid使用infolines外部主题，它将“简短机构”（在 的可选参数中提供的任何内容\institute）插入括号中。要删除这些，您必须重新定义整个footline模板，或对其进行修补。后者更简单，只需在加载主题后将以下内容添加到您的序言中即可实现：
\makeatletter
% Remove (parentheses) around "short institute" declaration
\patchcmd{\beamer@@tmpl@footline}% <cmd>
{(\insertshortinstitute)}% <search>
{\insertshortinstitute}% <replace>
{}{}% <success><failure>
\makeatother
