使用软件包中的出色宏tcolorbox，我在一本概率书中的每一章都写了带有解决方案的练习。因为我想将所有解决方案写在一章中，所以我在这里使用了我的问题中开发的真正巧妙的宏：
现在，我使用以下宏对章节进行“文字”编号：
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% MACRO FOR LITERAL NUMBERING CHAPTERS %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\newcommand\words[1]{\expandafter\xwords\csname c@#1\endcsname}
\def\xwords#1{\ifcase#1\or
one\or
two\or
three\or
four\or
five\or
six\or
seven\or
eight\or
nine\or
ten
\else
I need more words\fi}
\usepackage{etoolbox} %% comment if 'etoolbox' have been loaded before
\makeatletter
\patchcmd{\@makechapterhead}{\thechapter}{\words{chapter}}{}{}
\makeatother
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% END MACRO FOR LITERAL NUMBERING %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
并且我想对解决方案的标题使用相同的编号，例如Solutions of the exercises of the chapter one，
Solutions of the exercises of the chapter two.. ETC。
我怎样才能做到这一点 ？
我在这里给出使用的 .tex 文件：

以及一些“有趣”的页面的编辑……
编辑。我使用包编辑我的问题以给出答案pgfplots，我给出的是“答案”，但网站的网站管理员说我必须编辑我的问题才能给出答案，我这样做了！
序言中的以下命令：
\def\mywordscounter{{"zero","one","two","three"}} %%% You can go far from..
%% Counters of pgf begins always by 0...
%% The non-numeric-values must be between " "
% Formatting command as a 'headline' of the solutions of chapter X
\NewDocumentCommand{\solutionchapterformat}{m}{%
\section{Solutions of the exercises of the chapter \protect\pgfmathparse{\mywordscounter[#1]}\pgfmathresult}%
}
可以完成这项工作。可以注意到，根据@ChristianHupfer的建议，在命令\protect之前添加了命令，它提供了合适的输出。\solutionchapterformat
不幸的是，我的文件有问题，因为其内容是错误的！这是更新后使用的 tex 文件：

答案2
我可以通过使用pgfplots包来解决我的问题，该包可以定义“文字”计数器。我的问题序言中的以下命令：
\usepackage{pgfplots}
\def\mywordscounter{{"zero","one","two","three"}} %%% You can go far from..
%% Counters of pgf begins always by 0...
%% The non-numeric-values must be between " "
% Formatting command as a 'headline' of the solutions of chapter X
\NewDocumentCommand{\solutionchapterformat}{m}{%
\noindent\bgroup\bfseries Solutions of the exercises of the chapter \pgfmathparse{\mywordscounter[#1]}\pgfmathresult\egroup%
}
给出了合适的行为。感谢 Christian Hupfer 提供的原始精美宏。
但还有最后一个问题！如果我想以节的格式输出解决方案的标题。如果我使用以下命令：
\NewDocumentCommand{\solutionchapterformat}{m}{%
\section{Solutions of the exercises of the chapter \pgfmathparse{\mywordscounter[#1]}\pgfmathresult}%
}
我收到错误信息：
! Incomplete \iffalse; all text was ignored after line ...
我在这里做错了什么？
