我怎样才能强制书目项目不跨页面分割？描述了如何设置参考书目的惩罚。我试过了，但它不适用于natbib。如果我在文件中写入惩罚.bbl，它会起作用，但由于它经常被覆盖，所以这不是一个好的解决方案。有办法解决这个问题吗？

答案1
在“begin”部分末尾添加代码：
\usepackage{etoolbox}
\makeatletter
\apptocmd{\thebibliography}{%
\clubpenalty\@M
\@clubpenalty\clubpenalty
\widowpenalty\@M
}
{}{}
\makeatother
使用您的示例代码，第二页将出现两行，而不是一行。
答案2
您可以使用\interlinepenalty：
.....
\usepackage{etoolbox}
\makeatletter
\AtBeginEnvironment{thebibliography}{%
\interlinepenalty=10000
}
.....
\makeatother
答案3
与其尝试“修补”natbib 对thebibliography环境的重新定义，不如直接复制 natbib 的代码并简单地用 替换惩罚4000因子10000。
相关代码片段从文件的第 1063 行开始natbib.sty。
在您的代码中，删除以下行
\usepackage{etoolbox}
\makeatletter
\AtBeginEnvironment{thebibliography}{%
\clubpenalty10000
\@clubpenalty \clubpenalty
\widowpenalty10000}
\makeatother
并将其替换为
\makeatletter
\renewenvironment{thebibliography}[1]{%
\bibsection
\parindent\z@
\bibpreamble
\bibfont
\list{\@biblabel{\the\c@NAT@ctr}}{\@bibsetup{#1}\global\c@NAT@ctr\z@}%
\ifNAT@openbib
\renewcommand\newblock{\par}%
\else
\renewcommand\newblock{\hskip .11em \@plus.33em \@minus.07em}%
