我正在尝试使用\fontfamily命令为文档中的特定内容插入特定类型的字体。此外，使用该命令\renewcommand{\ttdefault}{<Font Name>}似乎也不起作用。这些命令相对简单，我基本上只想更改字体系列。这可能是由于我的某些软件包存在兼容性问题吗？
以下是我得到的结果示例：
我的源代码：

OK guys. In what follows, I will provide you with a some notes about your pitfalls, why they are pitfalls and how to avoid or rectify them.
\paragraph{Area Conversion.} I \strong{noted that many} of you make mistakes when converting from $cm^{2}$ to $m^{2}$. When doing conversion of areas from one unit to another, the original unit is scaled \emph{twice}. Hence, converting from $cm^{2}$ to $m^{2}$ requires that you divide over $100$ two times. For instance, $30 \thickspace cm^{2} = \frac{30}{100\times100} \thickspace m^{2} \Rightarrow 30 \thickspace cm^{2} = 0.003 \thickspace m^{2}$.
\paragraph{Neglecting Air Gap in Iron Cores.} The relative permeability of iron can be thousands of times that of air ($\mu_{r} = 2000-100,000$), which means that the reluctance of the air gap $\displaystyle \mathcal{R}_{g} = \frac{l_{g}}{\mu_{\note} A_{g}}$ would be much more than the reluctance of the core $\displaystyle \mathcal{R}_{c} = \frac{l_{c}}{\mu_{r}\mu_{\note} A_{c}}$. Hence, significant error would definitely result in if you did not take into account the air gap in magnetic~circuits.

您不能使用任意名称作为字体系列。必须先声明它们。使用 fontspec 时，您可以使用 来执行此操作NFSSFamily，但也可以简单地定义新的字体系列。
\documentclass[12pt]{book}
\usepackage{fontspec}
\setmainfont{TeX Gyre Adventor}
\setmonofont{TeX Gyre Cursor}
\newfontfamily\verbatimfont{DejaVu Sans Mono}[NFSSFamily=dejamono]
\begin{document}
standard text
{\ttfamily courier}
{\fontfamily{dejamono}\selectfont DejaVu Sans Mono} is then equivalent to
{\verbatimfont DejaVu}
\end{document}
