Beamer 部分标题幻灯片

Question

我希望每个部分之前都有一个部分标题幻灯片（但不是完整的目录），但我不希望幻灯片在标题上方显示默认的“第 1 部分”，就像以下 MWE 一样：

\documentclass[slidestop,compress,mathserif,12pt,xcolor=dvipsnames,xcolor=table{beamer}
\setbeamertemplate{caption}{\insertcaption}
\definecolor{LHCblue}{RGB}{4, 114, 255}
\usecolortheme[named=LHCblue]{structure}
\usepackage[bars]{beamerthemetree} % Beamer theme v 2.2
\usepackage{kerkis}
\usepackage{geometry}
\usepackage{adjustbox}
\usepackage{multimedia}
\usepackage{tikz}     
\usepackage{subfigure}
\usepackage{ latexsym }
\usepackage{graphics}
\mode<presentation>
\newcommand*\oldmacro{}%
\let\oldmacro\insertshorttitle%
\renewcommand*\insertshorttitle{%
\oldmacro\hfill%
\insertframenumber\,}%/\,\inserttotalframenumber
\setbeamertemplate{footline}[frame number]
 \usetheme{Ilmenau} 
 \useoutertheme[subsection=true]{smoothbars}
\useinnertheme{circles} %rectangle bullet points instead of circle ones
\usepackage{beamerthemebars}
\setbeamercolor{navigation symbols dimmed}{fg=red!80!black}
\setbeamercolor{navigation symbols}{fg=red!80!black}
\title{Title}
\author[Author\hspace{2.5cm}]{Author}
\institute{Institute}

 \AtBeginSection[]
{
  \begin{frame}

    \sectionpage
 \end{frame}
 }


\usepackage{textpos}

\begin{document}

\begin{frame}
\titlepage
\end{frame}
\section{First Section}
\end{document}

Answer 1

您可以重新定义章节页面以删除Section xxx章节标题上方的行。

关于您的代码的其他一些评论：

• ]第一行缺失

• 你可以xcolor=dvipsnames,xcolor=table将它们组合成xcolor={dvipsnames,table}

• 该slidestop选项已过时，请使用该t选项

• 该mathserif选项已过时，请\usefonttheme[onlymath]{serif}改用

• 您不需要加载graphics包，beamer 已经加载graphicx
