-The \thestyle{} package is an extension to \LaTeX\ to allow author--year
-citations along with numerical citations. Standard \LaTeX\ permits only
-numerical, whereas all extensions for author--year prior to the release of
-\thestyle{} in 1993 were limited to just that. Since they normally added new
-commands (as \thestyle{} does  too), documents written with them could only be
-used with numerical citations after extensive editing.
+\thestyle{} 宏包扩展了 \LaTeX{} 的参考文献引用能力，支持数字格式的引用和
+作者--年份引用格式。
+标准的 \LaTeX{} 只提供了数字格式的引用，而在 \thestyle{} 发布的 1993 年之前，所有
+提供作者--年份引用格式的宏包，通常都是通过添加新的命令来支持作者--年份引用格式。
+由于这一限制，使用这些宏包的书写的文档在后续修改之时，很难改变引用格式。
 
-The \thestyle{} package has changed that; switching from author--year to
-numerical citations is a matter of an option, with no alterations to the
-source text. It has now become part of the standard \LaTeX\ installations,
-and is supported (demanded) by many journals. It is the citation package of
-choice by most of the \LaTeX\ community, mainly because of its flexibility
-and configurability.
+\thestyle{} 宏包的出现改变了这一现状；使用 \thestyle{} 宏包的文档在作者--年份格式与
+数字引用格式之间的切换非常简单，只需要修改宏包选项即可，不需要做任何额外的改动。
+\thestyle{} 宏包已作为标准 \LaTeX{} 的一部分随之安装，并且支持许多期刊（同时也被这些期刊
+作为依赖）。大多数 \LaTeX{} 社区选择 \thestyle{} 宏包，主要就是因为 \thestyle{} 宏包
+的灵活性和可定制性。
 
-Like all packages, it is loaded in the document preamble, with possible options,
-with, e.g.\
+和其他宏包一样，\thestyle{} 宏包需要在文章导言区中加载，例如：
 \begin{quote}
   |\usepackage[sectionbib,square]{natbib}|
 \end{quote}
-The option \texttt{sectionbib} specifies that, when used with the package
-\texttt{chapterbib}, the bibliography will appear as a section at the end of
-each chapter (Section~\ref{sec:chapbib}). The \texttt{square} option says
-that references are to be enclosed in square bracket rather than round
-parentheses. See Section~\ref{sec:opts} for a complete list of options.
+开启 \opt{sectionbib} 选项时，载入 \pkg{chapterbib} 宏包，则参考文献列表将出现在每一个
+章节之后（参阅~\ref{sec:chapbib}）。\opt{square} 选项则指明文中引用时，
+引用记号将放在一对方括号中，而不是一对圆括号中。第 \ref{sec:opts} 节列出了所有可用的选项。
 
-The document text itself begins with, e.g.
+本文档在正文开始处使用了如下参考文献格式，
 \begin{quote}
 \begin{verbatim}
 \begin{document}
 \bibliographystyle{plainnat}
 \end{verbatim}
 \end{quote}
-which specifies \texttt{plainnat} to be the bibliography style used by the
-\btx\ program that generates the actual bibliography from a database. The
-style \texttt{plainnat} is the \thestyle{} version of the standard \texttt{plain}
-(numerical only) style. See Section~\ref{sec:plainnat} for other styles, or
-search the installation for \texttt{.bst} files.
+此处，我们通过 \cs{bibliographystyle} 命令选择 \bst{plainnat} 为参考文献格式，\btx{}
+将会据此从数据库中抽取数据生成实际的参考文献列表。\bst{plainnat} 是 \thestyle{} 风格的
+\bst{plain} 格式，只支持数字引用格式。第~\ref{sec:plainnat} 节列出了所有可用的参考文献格式文件（\file{.bst} 文件）。
 
-The |\bibliographystyle| command can be given anywhere in the document, but
-it makes sense to add it at the start where it can be easily identified (and
-modified).
+\cs{bibliographystyle} 命令可以放在文档的任何位置，但放在正文开始处更加清晰明了且易于修改。

-  |\citet{jon90}| for a \emph{textual} one, as Jones et al. (1990).
+  \cs{citet}\Arg{jon90} 生成文本类的引用，如 Jones et al. (1990)
 \end{quote}
-Both |\citep| and |\citet| are defined by \thestyle{} and are thus not
-standard. The standard \LaTeX\ command |\cite| should be avoided, because it
-behaves like |\citet| for author--year citations, but like |\citep| for
-numerical ones. There are many other commands for other special effects
-(Section~\ref{sec:excite}).

-In the above examples, \texttt{jon90} is the identifying key for the
-reference, as found in the \btx\ database, or in the \texttt{thebibliography}
