查看文档属性,“细”字体被标识为 CMDUNH10,因此您可以这样说
\documentclass{article}
\usepackage[margin=2cm]{geometry}
\usepackage[T1]{fontenc}
\newcommand\lgh{\fontsize{17}{21}\usefont{T1}{cmdh}{m}{n}}
\newcommand\myrule{\par\noindent\rule{\textwidth}{4pt}\par}
\begin{document}
\myrule\medskip
\noindent{\lgh CS61A\hfill Structure and Interpretation of Computer Programs \\[0.5ex]

\myrule
\end{document}
