我想删除块标题，因为标题将写在标题中的图中。我尝试通过设置来使用空标题\settitle{}。

Answer 1

\maketitle我找到了文件里对应的源代码.cls，并做了一些小小的修改。

% \maketitle[titletotopverticalspace=7cm]
\makeatletter
\setkeys{title}{titletotopverticalspace=7cm}
\setlength{\titlepostop}{0.5\textheight-\TP@titletotopverticalspace}
\setlength{\titleposbottom}{\titlepostop-\titleheight}
\setlength{\TP@blocktop}{\titleposbottom-\TP@titletoblockverticalspace}
\makeatother
