如何将图表和文本置于页面的垂直中心？现在图表高于文本。

Answer 1

对于垂直居中，您需要在图像的垂直中心定义图像的基线。为此，建议使用adjustbox选项valign=m：

\documentclass{article}
\usepackage{varwidth}
\usepackage[demo]{graphicx}
\usepackage[export]{adjustbox}
\usepackage{xcolor}
\newsavebox{\graybox}
\newenvironment{note}
    {\begin{center}
        \begin{minipage}{\textwidth}
        \begin{lrbox}{\graybox}
        \begin{varwidth}{0.80\textwidth}
     }{\end{varwidth}
       \end{lrbox}
       \includegraphics[width=0.15\textwidth,valign=m]{note3.png}\hfill
       \colorbox{gray!30}{\usebox{\graybox}}
       \end{minipage}
       \end{center}
       }

\usepackage{lipsum}

\begin{document}
\lipsum[11]
\begin{note}
        He was an Austrian physicist famous for his founding contributions in the fields of
    statistical mechanics and statistical thermodynamics. He was one of the most
    important advocates for atomic theory at a time when that scientific model was
    still highly controversial.
