像这样?
通过使用caption
包:
\documentclass{article}
\usepackage{graphicx}
\usepackage[font=small,
width=0.9\textwidth]{caption}
\usepackage{lipsum}
\begin{document}
\lipsum[11]
\begin{figure}[ht]
\centering
\includegraphics[width=0.9\linewidth]{example-image}
\caption{Experimental set up Diagram of the Raman spectroscopy equipment (images adapted and token from the fabricators catalogs)}
\label{fig:SetUp}
\end{figure}
\lipsum[12]
\end{document}
或图像宽度等于文本宽度和包装选项:
\usepackage[font=small,
margin={11mm,11mm}]{caption}
