我搜索并花了几个小时研究如何使我的参考书目发挥作用。这是我的文档的开头：
\documentclass{article}
\usepackage{enumerate}
\usepackage{graphicx}
\usepackage[citestyle=alphabetic,bibstyle=apa,backend=biber,natbib=true]{biblatex}
\usepackage[american]{babel}
\usepackage[babel,threshold=2]{csquotes}
\newcommand*{\rom}[1]{\expandafter\@slowromancap\romannumeral #1@}
\title{Lab technologist/science professional}
\author{Jesslynn Westfall SN, SCC}
\addbibresource{labtechbib.bib}
\begin{document}
\maketitle
\section{Introduction}
Sometimes called medical laboratory science (MLS) professionals, lab technologists perform many tasks that help improve health care. Though they are sometimes called lab technicians, more schooling is required to become a technologist/scientist.\cite{MLT}
这就是结局
\printbibliography[heading=bibintoc,title={References}]
\end{document}
以下是我的参考书目的一个例子：
@misc{medtechschool,
mendeley-groups = {Nursing},
title = {{Medical Lab Scientist MLS (ASCP) Certification}},
url = {https://www.medicaltechnologyschools.com/medical-lab-scientist/mls-ascp-certification},
