参考书目不起作用；参考书目未出现在pdflatex和bibtex之后

Question

我正在写论文，我以前用乳胶写论文，一切正常。但对于长篇论文，我的参考书目出现了问题。

我了解到我应该通过

pdflatex MainFile
bibtex MainFile
pdflatex MainFile
pdflatex MainFile

在第二步之前，我没有遇到任何问题或警告。第二步之后，我在 MainFile.bbl 中看到了这个

\begin{thebibliography}{1}

\bibitem{Wielen}
S.~T. Abedon, P.~Hyman, and C.~Thomas.
\newblock Experimental examination of bacteriophage latent-period evolution as
  a response to bacterial availability.
\newblock {\em Applied and Environmental Microbiology}, 69:7499--7506, 2003.

\end{thebibliography}

我在 MainFile.blg 中有这个

This is BibTeX, Version 0.99dThe top-level auxiliary file: Yan_Thesis.aux
A level-1 auxiliary file: Titlepage/Titlepage.aux
A level-1 auxiliary file: Contents/Introduction.aux
The style file: unsrt.bst
Database file #1: Contents/thesis_reference.bib

一切似乎都很好。但第三步却出错了

LaTeX Warning: Citation `Wielen' on page 1 undefined on input line 5.

l.1 \begin{thebibliography}{1}

? 

进程已终止...

有人知道这里出了什么问题吗？

以下是我的 MainFile.tex
