我试图将此处的图像向下移动，但它不会移动。即使使用 vspace，图像也会向下移动，但标题会向上移动。它覆盖了进度条，看起来不太好。

谢谢大家的帮助。

要调整框架，您必须使用vspace。我认为您应该使用em统一。例如，\vspace{1em}添加 1 个字符的垂直空间。

为了使投影仪不与进度条重叠，您必须告诉他框架不高于其限制。因此，我主要\vspace{-1em}在框架底部和图形后添加负空间以获得预期结果。

\begin{frame}{\emph{M. tuberculosis} antigens and particulates are confined within the phagosome}
   \begin{columns}
   \column{0.7\textwidth}%
   \includegraphics[width=1.0\textwidth]{mycobacteriumvstubcerolosis.png}
   \vspace*{-.5em}\captionof{figure}{\footnotesize Left quadrant: dyes from labeled- \emph{M. tuberculosis} remain confined within phagosomes. Right quadrant: dyes from labeled-\emph{L. monocytogenes} were released into the cell <10 mins after infection. Arrows indicate bacteria-containing phagosomes.}
   \column{0.4\textwidth}
   \begin{itemize}
      \itemsep1em
      \item The mycobacterial phagosome appears to be impermeable to macromolecules
      \item Membrane-impermeable fluorescent molecules were \alert{retained} in phagosomes across all maturation stages
   \end{itemize}
\end{columns}
\vspace{-1em}
\pause
\metroset{block=fill}
\begin{alertblock}{Seclusion from the classical MHC-I pathway is apparent.}
      There must be another alternative pathway for antigen delivery.
\end{alertblock}
\vspace{-1em}
\end{frame}

当我编译这个例子时，它正如你所希望的那样工作。
