为什么此 elsarticle 代码无法正确编译我的 .bib 文件？

Question

我使用的示例代码来自上一个问题。

上一个问题中的 elsarticle 文档类的代码是：

%%%%%%%%%%%%%%%%%%%%%%%%%%%%% test_els.tex %%%%%%%%%%%%%%%%%%%%%%%%%%%
\documentclass[preprint,12pt]{elsarticle}

\begin{document}
\section{Introduction}
Several researchers studied ruin probability, but for a survey see\cite{AsmussenandAlbrecher2010}.
For bulk arrival queues see \cite{ChaudhryandTempleton1983}

\bibliographystyle{model1-num-names}
\section{\refname}

\nocite{*}
\bibliography{mybib}

\end{document}

我将其逐字逐句复制到我的 MiKTeX 中。随附的是我的 .bib 文件 (mybib)：

%%%%%%%%%%%% mybib.bib %%%%%%%%%

@BOOK{AsmussenandAlbrecher2010,
  author  = {Asmussen, S. and Albrecher, H.},
  title   = {Ruin probabilities},
  edition = {2nd ed.},
  address = {Singapore},
  publisher = {World Scientific},
  year    = {2010}
}

@ARTICLE{Botta1987,
  author  = {Botta, R. F. and Harris, C. M. and Marchal, W. G.},
  title   = {Characterisation of generalised hyperexponential distribution functions},
  journal = {Stochastic Models}, 
  volume  = {3},
  year    = {1987},
  pages   = {115-148}
}

@BOOK{ChaudhryandTempleton1983,
  author  = {Chaudhry, M. L. and Templeton, J. G. C.},
  title   = {A First Course in Bulk Queues},
  address = {New York},
  publisher = {Wiley},
  year    = {1983}
}

保存该 .bib 后，我在 MiKTeX 中运行了 .tex 文件（PDFLatex > BibTex > PDFLatex > PDFLatex）。我似乎无法避免这输出。代码很简单，但我找不到我做错的地方。有什么建议吗？
