书目样式，Elsevier

Question

我正在使用 Texstudio 撰写期刊论文。我遇到的问题是，使用以下序言，参考书目样式的结果在我的论文正文中如下

我的论文中使用的序言如下

\documentclass[preprint,12pt,authoryear]{elsarticle}
% !TeX spellcheck = en_US

\begin{document}


\section*{References}
\bibliography{bilbiography}

%% else use the following coding to input the bibitems directly in the

\end{document}

\endinput

一位审稿人告诉我，参考文献应该编号，并按照其在文中出现的顺序出现。

我不知道如何解决这个问题。有人能帮助我吗？
