两个方法，第一个方法就是用 `tabular` 环境，如下 ```tex \begin{tabular}{p{0.5\textwidth} p{0.5\textwidth}} \vspace{0pt} \includegraphics[width=0.49\textwidth]{example-image-a} & \vspace{0pt} \includegraphics[width=0.49\textwidth]{example-image-b} \end{tabular} ``` 第二个用 `adjustbox` ```tex \documentclass{article} \usepackage[export]{adjustbox}% http://ctan.org/pkg/adjustbox \begin{document} \begin{figure} \centering \includegraphics[scale=0.5,valign=t]{example-image-a} \includegraphics[scale=0.3,valign=t]{example-image-b} \caption{A caption\label{fig:scaled_diss}} \end{figure} \end{document} ```
