主要.tex：
\documentclass[12pt]{article}

\usepackage[numbers]{natbib}
\renewcommand{\bibsection}{\large \textbf{REFERENCES}}
\makeatletter
\renewcommand{\@biblabel}{\hfill}
\makeatother

参考文献：
@article{esry2007,
title = {General Theory of Carrier-Envelope Phase Effects},
author = {Roudnev, V. and Esry, B. D.},
journal = PRL,
volume = {99},
number = {22},
pages = {220406},
year = {2007},
publisher = {APS}
}

正确地重新定义就足够了\@biblabel。您可能希望更改3em为您认为合适的任何其他长度。
\documentclass[12pt]{article}
\usepackage[english,turkish]{babel}
\usepackage[numbers]{natbib}
\renewcommand{\bibsection}{\begin{center}\large \textbf{REFERENCES}\end{center}}
\makeatletter
\renewcommand{\@biblabel}[1]{\makebox[3em][l]{#1.}}
\makeatother
