我的整个文档都是 Palatino 字体（我认为），只有公式列表有衬线字体。我希望一切都统一。以下是示例代码：
\documentclass[a4paper,11pt,openright]{report}
\usepackage[ngerman]{babel} % Deutsche Trennmuster
\usepackage{newtxtext, newtxmath} % Schriftart Palatino & passende Mathe-Schrift
\usepackage[T1]{fontenc} % Einstellung Schriftkodierung
\newcounter{myequation}[chapter]
\renewcommand{\themyequation}{\thechapter.\arabic{myequation}}
\newcommand{\myequation}[1]{\refstepcounter{myequation}\label{#1}\addcontentsline{equ}{myequations}{\protect\numberline{\themyequation}\hspace{0.5em}$\displaystyle \texttt{#1}$}}
\newlistof{myequations}{equ}{Formelverzeichnis}
\setlength{\cftmyequationsnumwidth}{2em}
\begin{document}
