封面中的标题超出了页面边界

Question

我在与主代码不同的文件中使用以下代码来布局我的论文封面：

\noindent\rule{\linewidth}{1mm}\\[1.4em]
{\noindent\Huge\sffamily
 \begin{tabular*}{\linewidth}{@{}c@{}}
   \thetitle\\[.5em]
   {\huge\theauthor}\\
 \noindent\rule{\linewidth}{1mm}\end{tabular*}}

但是，结果标题超出了页面范围（见附图）。有人知道如何解决这个问题吗？

以下是主文档的代码。将出现上述问题的文件插入到\include{cover}代码中的第 行。

Answer 1

一个可能的（简单）解决方案是将标题页直接作为主文档的一部分。例如：

\documentclass[c5paper,titlepage,11.5pt]{book}%{report}
\usepackage{geometry}
\geometry{c5paper,top=2.5cm,bottom=2.5cm,left=1.93cm,right=2.1cm}
\usepackage{libertine}
\usepackage[T1]{fontenc}
\usepackage{setspace}
\usepackage{array}      % <---
\usepackage{booktabs}
\onehalfspacing
\usepackage{hyperref}

\begin{document}

\frontmatter
\thispagestyle{empty}
\mbox{}
\vfill
    \begin{center}
\begin{tabular*}{\linewidth}{ >{\centering\arraybackslash\sffamily\Huge}p{\linewidth} }
    \toprule[1mm]
    \medskip
Investigating the Chemistry of the Universe at the Atomic Level
                    \\
                    \\[3em]
\huge
Arabel Snorkeling   \\[1em]
    \bottomrule[1mm]
\end{tabular*}

\vfill
\today
\vfil\mbox{}
    \end{center}

\cleardoublepage

\addtocontents{toc}{\protect\setcounter{tocdepth}{-1}}
\tableofcontents
\listoffigures
\listoftables

\addtocontents{toc}{\protect\setcounter{tocdepth}{3}}
\setcounter{secnumdepth}{3}
\cleardoublepage

\mainmatter
\part{The main part}
\chapter{Background}

\end{document}

（从序言中我删除了所有与标题页不相关的包。

注意：软件包hyperref应在前言中最后加载。同时删除所有加载两次的软件包。
