我有以下 MWE
\documentclass[xcolor=pdftex,t,11pt]{beamer}
\begin{document}
\renewcommand{\theequation}{A\arabic{equation}}
\setcounter{equation}{0}
\section{Appendix}
\begin{frame}[label=C1]
\frametitle{Appendix}
\framesubtitle{Derivation of Eq. 7}
\begin{itemize}
\item In order to derive Eq. 7, let us re-write Eq. {\ref{6}} as follows:\medskip
\begin{eqnarray}
\Delta _{i}=V_{i}^{F}-\left(1-p_{j}\right)f_{i}\left(L_{i}^{N}\right)-p_{i}f_{j}\left( L_{j}^{N}\right)-v_{i}\left(T-L_{i}^{N}\right)
\begin{array}{c}
> \\
= \\
<%
\end{array}%
0
\end{eqnarray}
\end{itemize}
\end{frame}
\end{document}
我想知道如何在 0 和方程式数字之间留出一些空格。有什么提示吗？提前谢谢
答案1
切勿使用。例如，eqnarray它与 不兼容。hyperref
如果删除所有无用的\left和，\right并使用三重关系的正确符号，则方程将符合要求。如果没有itemize，则更符合要求。
要手动设置标签，请使用\tag。
