这是标准类别目录的众所周知的局限性。它有点取决于使用的字体（因为较窄的字体不太可能显示问题）。
最简单的解决方法是将类似这样的内容添加到你的序言中
\usepackage{tocloft}
\advance\cftsecnumwidth 0.5em\relax
\advance\cftsubsecindent 0.5em\relax
\advance\cftsubsecnumwidth 0.5em\relax
例如：
\documentclass{book}
\usepackage{tocloft}
\advance\cftsecnumwidth 0.5em\relax
\advance\cftsubsecindent 0.5em\relax
\advance\cftsubsecnumwidth 0.5em\relax
\begin{document}
\tableofcontents
\setcounter{chapter}{11}
\setcounter{section}{8}
\section{Enthalpy Concentration Diagram}
\section{Single stage flash vaporization}
\section{Reflux Ratio}
\subsection{Minimum reflux ratio}
\subsection{Optimum reflux ratio}
\end{document}
