bibtex：参考编号顺序问题

Question 1

由于您在命令\listoffigures前面添加了\cite，因此前两个引用的参考文献是\captions 里面的参考文献。

因此它们按以下顺序出现：

阿克曼02

奥尔森09

埃斯特班04

雷蒙迪诺06

阮12

移动\listoffigures到文档末尾即可解决问题。

\documentclass[a4paper, 11pt, oneside]{Thesis}  % Use the "Thesis" style, based on the ECS Thesis style by Steve Gunn
%\documentclass{book}  % Use the "Thesis" style, based on the ECS Thesis style by Steve Gunn

\usepackage[square, numbers, comma, sort&compress]{natbib}  % Use the "Natbib" style for the references in the Bibliography
\usepackage{verbatim}  % Needed for the "comment" environment to make LaTeX comments
\usepackage{vector}  % Allows "\bvec{}" and "\buvec{}" for "blackboard" style 6
\usepackage{amssymb}


\begin{document}

\mainmatter   % Begin normal, numeric (1,2,3...) page numbering
\pagestyle{fancy}
%\input{Chapter1} % Introduction

This is the first \cite{Ackermann02}

\begin{figure}[h]
 \centering
 \includegraphics[width = 0.4\textwidth]{Figure1.jpg}
 \caption{Figure1 \cite{Ackermann02}. }
 \label{fig:Figure1}
\end{figure}

This is the second \cite{Esteban04, Remondino06, Nguyen12}.

Sixth is this \cite{Olsen09}.

\begin{figure}[h]
 \centering
 \includegraphics[scale=1.0]{Figure2.eps}
     \hspace{ 5.5 mm}\caption{ (taken from \cite{Olsen09}). }
\label{fig:Figure2}
\end{figure}

\label{Bibliography}
\lhead{\emph{Bibliography}}  % Change the left side page header to "Bibliography"
\bibliographystyle{unsrtnat}  % Use the "unsrtnat" BibTeX style for formatting the Bibliography
\bibliography{Bibliography}  % The references (bibliography) information are stored in the file named "Bibliography.bib"

\lhead{\emph{List of Figures}}  % Set the left side page header to "List if Figures"
\listoffigures  % Write out the List of Figures

\end{document}  % The End

如果您无法\listoffigures在文档末尾移动，您可以\nocite在之后按正确的顺序引用\begin{document}：

 \documentclass[a4paper, 11pt, oneside]{Thesis}  % Use the "Thesis" style, based on the ECS Thesis style by Steve Gunn
%\documentclass{book}  % Use the "Thesis" style, based on the ECS Thesis style by Steve Gunn

\usepackage[square, numbers, comma, sort&compress]{natbib}  % Use the "Natbib" style for the references in the Bibliography
\usepackage{verbatim}  % Needed for the "comment" environment to make LaTeX comments
\usepackage{vector}  % Allows "\bvec{}" and "\buvec{}" for "blackboard" style 6
\usepackage{amssymb}


\begin{document}

\nocite{Ackermann02}
\nocite{Esteban04}
\nocite{Remondino06}
\nocite{Nguyen12}
\nocite{Olsen09}

\lhead{\emph{List of Figures}}  % Set the left side page header to "List if Figures"
\listoffigures  % Write out the List of Figures

\mainmatter   % Begin normal, numeric (1,2,3...) page numbering
\pagestyle{fancy}
%\input{Chapter1} % Introduction

This is the first \cite{Ackermann02}

\begin{figure}[h]
 \centering
 \includegraphics[width = 0.4\textwidth]{Figure1.jpg}
 \caption{Figure1 \cite{Ackermann02}. }
 \label{fig:Figure1}
\end{figure}

This is the second \cite{Esteban04, Remondino06, Nguyen12}.

Sixth is this \cite{Olsen09}.

\begin{figure}[h]
 \centering
 \includegraphics[scale=1.0]{Figure2.eps}
     \hspace{ 5.5 mm}\caption{ (taken from \cite{Olsen09}). }
\label{fig:Figure2}
\end{figure}

\label{Bibliography}
\lhead{\emph{Bibliography}}  % Change the left side page header to "Bibliography"
\bibliographystyle{unsrtnat}  % Use the "unsrtnat" BibTeX style for formatting the Bibliography
\bibliography{Bibliography}  % The references (bibliography) information are stored in the file named "Bibliography.bib"

\end{document}  % The End

还有两种可能：

如果您不需要在“图片列表”中打印参考文献的链接，您可以打印标题的“简短形式”。例如，用代替\caption{ (taken from \cite{Olsen09}). }。\caption[Fig. 2]{ (taken from \cite{Olsen09}). }这样\cite就不会收集相应的内容。
在.bib文件中，将参考文献按照它们在“参考书目”中出现的准确顺序排列，并放在\nocite{*}紧接之后\begin{document}。无论如何，请注意，在这种情况下，文件中包含的所有参考文献.bib都将被打印，即使是您尚未记录的参考文献\cite...

Answer

由于您在命令\listoffigures前面添加了\cite，因此前两个引用的参考文献是\captions 里面的参考文献。
