例子

\usepackage[colorlinks,urlcolor=blue]{hyperref}

在导言区加入宏包首行 \usepackage{indentfirst} 就可以了.使用命令 设置 缩进的距离 \setlength{\parindent}{2em},

\usepackage{setspace}
\setlength{\baselineskip}{20pt}

\renewcommand{\contentsname}{目录}

需要注意的是，\renewcommand{\contentsname}{...} 不能写在导言区，要写在 \tableofcontents 之前。
其它预设名如下
\abstractname         Abstract
\alsoname         see also (makeidx package)
\appendixname         Appendix
\bibname         Bibliography (report,book)
\ccname         cc (letter)
\chaptername         Chapter (report,book)

\partname         Part
\refname         References (article)
\seename         see (makeidx package)
\tablename         Table (for caption)如：
