投影机中带有标题的两列项目

Question

在下图中您可以清楚地看到标题和项目没有对齐。

这是上图的代码，

\begin{frame}
    \frametitle{Applications of nanofluids}

\begin{columns}
  \column{0.5\textwidth}\centering
    {\bf{Heat Transfer Applications}}\\[.2cm]
    \begin{itemize}
    \item Industrial Cooling Applications
    \item Nuclear Reactors
    \item Extraction of Geothermal Power\\[.2cm]
    \end{itemize}
  \column{0.5\textwidth}\centering
    {\bf{Automotive Applications}}\\[.2cm]
    \begin{itemize}
    \item Nanofluid Coolant
    \item Nanofluid in Fuel
    \item Nanofluid in Fuel\\[.2cm]
    \end{itemize}
\end{columns}
\begin{columns}
  \column{0.5\textwidth}\centering
    {\bf{Electronic Applications}}\\[.2cm]
    \begin{itemize}
    \item Cooling of Microchips
    \item  Microscale Fluidic Applications    
    \end{itemize}
  \column{0.5\textwidth}\centering
    {\bf{Biomedical Applications}}\\[.2cm]
    \begin{itemize}
    \item Nanodrug Delivery
    \item  Nanocryosurgery
    \end{itemize}
\end{columns}
\end{frame}

有什么建议可以改进它并使它看起来更好吗？

Answer 1

为了使标题水平对齐，我建议使用顶部对齐columns环境，对于垂直对齐，请删除\centering并且不要使用\bf。

\documentclass{beamer}

\begin{document}

\begin{frame}
\frametitle{Applications of nanofluids}

\begin{columns}[onlytextwidth,t]
    \begin{column}{0.48\textwidth}
        \textbf{Heat Transfer Applications}

    \begin{itemize}
        \item Industrial Cooling Applications
        \item Nuclear Reactors
        \item Extraction of Geothermal Power
    \end{itemize}
  \end{column}
  \begin{column}{0.48\textwidth}
    \textbf{Automotive Applications}

        \item Nanofluid in Fuel
    \end{itemize}
  \end{column}
\end{columns}
