自动以粗体和小写字母显示章节或节标题

Question

我有一个非常基本的问题，基本上是这个旧的。

怎样才能使章节或节标题中的小型大写字母变为粗体？

低于 MWE。

\RequirePackage{fix-cm}
\documentclass[10pt]{book}

\usepackage[english]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usepackage{lmodern} % To switch to Latin Modern
\rmfamily % To load Latin Modern Roman and enable the following NFSS declarations.
% Declare that Latin Modern Roman (lmr) should take
% its bold (b) and bold extended (bx) weight, and small capital (sc) shape, 
% from the corresponding Computer Modern Roman (cmr) font, for the T1 font encoding.
\DeclareFontShape{T1}{lmr}{b}{sc}{<->ssub*cmr/bx/sc}{}
\DeclareFontShape{T1}{lmr}{bx}{sc}{<->ssub*cmr/bx/sc}{}


%
\usepackage{titlesec}


\makeatletter
\def\@makechapterhead#1{%
  \vspace*{-21\p@}%
  {\parindent \z@ \raggedright \normalfont
    \interlinepenalty\@M
    \huge\bfseries\sc  \thechapter.\quad #1\par\nobreak
    \vskip 40\p@
  }}
\makeatother


\usepackage{tocloft}
\renewcommand{\cfttoctitlefont}{\huge\bfseries\sc}


\title{Title}
\author{Author}

\begin{document}
\maketitle

\tableofcontents

\chapter{Chapter}
\section{Section}

\end{document}

具体来说，我目前正在使用上面链接中用户@Blaisorblade 提供的答案以及 titlesec，但实际上什么也没有发生：正如所注意到的，章节标题是小写字母，但不是粗体，目录条目也是如此。

欢迎任何反馈！

正如已经说过的在 Will 的回答中对于您链接的问题，您不应该使用\sc，因为这个弃用的字体命令也会停用以前的\bfseries。请\scshape改用：

\RequirePackage{fix-cm}
\documentclass[10pt]{book}

\usepackage[english]{babel}
\usepackage[utf8]{inputenc}% Note: Not needed since LaTeX 2018/04/01.
\usepackage[T1]{fontenc}

\usepackage{lmodern} % To switch to Latin Modern
\rmfamily % To load Latin Modern Roman and enable the following NFSS declarations.
% Declare that Latin Modern Roman (lmr) should take
% its bold (b) and bold extended (bx) weight, and small capital (sc) shape, 
% from the corresponding Computer Modern Roman (cmr) font, for the T1 font encoding.
\DeclareFontShape{T1}{lmr}{b}{sc}{<->ssub*cmr/bx/sc}{}
\DeclareFontShape{T1}{lmr}{bx}{sc}{<->ssub*cmr/bx/sc}{}

%
\usepackage{titlesec}% Note: Loaded but currently not used.


\makeatletter
\def\@makechapterhead#1{% Note: Instead of redefining \@makechapterhead, you could use the already loaded titlesec.
  \vspace*{-21\p@}%
  {\parindent \z@ \raggedright \normalfont
    \interlinepenalty\@M
    \huge\bfseries\scshape  \thechapter.\quad #1\par\nobreak
    \vskip 40\p@
  }}
\makeatother


\usepackage{tocloft}% Note: Instead of using tocloft, you could also redefine \@makeschapterhead similar to your redefinition of \@makechapterhead.
\renewcommand{\cfttoctitlefont}{\huge\bfseries\scshape}


\title{Title}
\author{Author}

\begin{document}
\maketitle

\tableofcontents

\chapter{Chapter}
\section{Section}

\end{document}
