我需要获取特定章节的编号部分在我的文档中将数字改为字母。如何实现？
MWE 游乐场：
\documentclass[a4paper,12pt,twoside,onecolumn,openright,final]{memoir}
\usepackage{lipsum}
\makeatletter
\@addtoreset{chapter}{part}
\makeatother
\begin{document}
\frontmatter
\tableofcontents
\mainmatter
\part{First part}
\chapter{First numbered chapter}
\lipsum[1]
\chapter{Second numbered chapter}
\lipsum[1]
\part{Second part}
% Set chapternum to Alpha here -- how?
\chapter{Alpha chapter A}
\lipsum[1]
\chapter{Alpha chapter B}
\lipsum[1]
% Reset chapternum to numeric -- how?
\part{Third part}
\chapter{Numbered again from 1}
\lipsum[1]
\end{document}

重新定义 \thechapter：
\documentclass[a4paper,12pt,twoside,onecolumn,openright,final]{memoir}
\usepackage{lipsum}
\makeatletter
\@addtoreset{chapter}{part}
\makeatother
\begin{document}
\frontmatter
\tableofcontents
\mainmatter
\part{First part}
\chapter{First numbered chapter}
\lipsum[1]
\chapter{Second numbered chapter}
\lipsum[1]
\part{Second part}
% Set chapternum to Alpha here -- how?
\renewcommand\thechapter{\Alph{chapter}}
\chapter{Alpha chapter A}
\lipsum[1]
\chapter{Alpha chapter B}
\lipsum[1]
% Reset chapternum to numeric -- how?
\part{Third part}
\renewcommand\thechapter{\arabic{chapter}}
\chapter{Numbered again from 1}
\lipsum[1]
\end{document}
