我采用了@Mico的解决方案这里根据附录部分的节数来确定Appendix目录中的单数或复数形式。但是我发现该解决方案有一个副作用，即由hyperref包 in生成的 PDF 中的章节书签pdfLatex是嵌套的。
\documentclass[11pt, a4paper, twoside]{book}
\RequirePackage[title,titletoc]{appendix}
\usepackage{ifthen}
\makeatletter
%% For source of "@seccntformat" command, see book "The LaTeX Companion"
\def\@seccntformat#1{\@ifundefined{#1@cntformat}%
{\csname the#1\endcsname\ \ }% default
{\csname #1@cntformat\endcsname}}% enable individual control
%% Individual control: '\section@cntformat'
\newcommand{\section@cntformat}{\thechapter.\thesection\ \ }
% Macros to redefine numbering of appendix sections
\newcommand{\appname}{} % dummy definition
\newcommand{\appsecnumbering}[1][0]{%
\ifthenelse{#1=1}{\renewcommand\appname{Appendix}}
{\renewcommand\appname{Appendices}}
\setcounter{section}{0}
\renewcommand\thesection{\thechapter.\Alph{section}}
\renewcommand{\section@cntformat}{\appendixname~\thesection\ \ }
\addtocontents{toc}{\medskip\protect{\mdseries\appname\par}}}
\newcommand\normalsecnumbering{%
\renewcommand{\thesection}{\thechapter.\arabic{section}}
\renewcommand{\section@cntformat}{\thesection\ \ }}
\let\origchapter\chapter
\renewcommand\chapter{\normalsecnumbering % first, reset numbering style
\origchapter} % second, execute the original \chapter command
\makeatother

使用该bookmark软件包可以修复此问题。只需添加\usepackage{bookmark}：
\documentclass[11pt, a4paper, twoside]{book}
\RequirePackage[title,titletoc]{appendix}
\usepackage{ifthen}
\makeatletter
%% For source of "@seccntformat" command, see book "The LaTeX Companion"
\def\@seccntformat#1{\@ifundefined{#1@cntformat}%
{\csname the#1\endcsname\ \ }% default
{\csname #1@cntformat\endcsname}}% enable individual control
%% Individual control: '\section@cntformat'
\newcommand{\section@cntformat}{\thechapter.\thesection\ \ }
% Macros to redefine numbering of appendix sections
\newcommand{\appname}{} % dummy definition
\newcommand{\appsecnumbering}[1][0]{%
\ifthenelse{#1=1}{\renewcommand\appname{Appendix}}
{\renewcommand\appname{Appendices}}
\setcounter{section}{0}
\renewcommand\thesection{\thechapter.\Alph{section}}
\renewcommand{\section@cntformat}{\appendixname~\thesection\ \ }
\addtocontents{toc}{\medskip\protect{\mdseries\appname\par}}}
\newcommand\normalsecnumbering{%
\renewcommand{\thesection}{\thechapter.\arabic{section}}
\renewcommand{\section@cntformat}{\thesection\ \ }}
\let\origchapter\chapter
\renewcommand\chapter{\normalsecnumbering % first, reset numbering style
