编号和显示参考文献时出现问题

Question

有人知道为什么编号会这样奇怪吗？我该如何修复它？

Coscia M. Cosica, F. Gianootti, and D. Pedreschi,“ A Classification for Community Discovery Methods in Complex Networks,” CoRR as/1206.3552 (2012)
[0] [1] F. Moradi, T. Olovsson, P. Tsigas, “ An Evaluation of Community Detection Algorithms on Large-Scale Email Traffic,” SEA 283-294 (2012)

这是.tex：

\begin{thebibliography}
\bibitem{Coscia} M. Cosica, F. Gianootti, and D. Pedreschi,`` A Classification for Community Discovery Methods in Complex Networks," \emph{CoRR} as/1206.3552 (2012) \\
\bibitem{Moradi} F. Moradi, T. Olovsson, P. Tsigas, `` An Evaluation of Community Detection Algorithms on Large-Scale Email Traffic," \emph{SEA} 283-294 (2012)
\end{thebibliography}

Answer 1

这是我得到的：

\documentclass{article}
\begin{document}
  \cite{Coscia,Moradi}

  \begin{thebibliography}{99}    %%<-- you have to give the width of largest number
    \bibitem{Coscia} M. Cosica, F. Gianootti, and D. Pedreschi,`` A Classification for Community Discovery Methods in Complex Networks," \emph{CoRR} as/1206.3552 (2012) 
    \bibitem{Moradi} F. Moradi, T. Olovsson, P. Tsigas, `` An Evaluation of Community Detection Algorithms on Large-Scale Email Traffic," \emph{SEA} 283-294 (2012)
  \end{thebibliography}
\end{document}
