双栏公式变单栏，需要加入begin\{widetext\}，双栏表格变单栏，需要把begin\{table\}改为begin\{table*\}。

\section{公式从双栏变单栏}
这是一个双栏公式
\begin{equation}
	E=mc^2.
\end{equation}
The equation that follows is set in a wide format, i.e., it spans the full page. 
The wide format is reserved for long equations
that cannot easily be set in a single column:
这是一个单栏公式
\begin{widetext}
	\begin{equation}
		{\cal R}^{(\text{d})}=
		g_{\sigma_2}^e
		\left(
		\frac{[\Gamma^Z(3,21)]_{\sigma_1}}{Q_{12}^2-M_W^2}
		+\frac{[\Gamma^Z(13,2)]_{\sigma_1}}{Q_{13}^2-M_W^2}
		\right)
		+ x_WQ_e
		\left(
		\frac{[\Gamma^\gamma(3,21)]_{\sigma_1}}{Q_{12}^2-M_W^2}
		+\frac{[\Gamma^\gamma(13,2)]_{\sigma_1}}{Q_{13}^2-M_W^2}
		\right)\;. 
		\label{eq:wideeq}
	\end{equation}
\end{widetext}
然后还原双栏。
\section{表格从双栏变单栏}
下面是一个双栏表格和双栏表格：
\begin{table}
\caption{\label{tab:table1}A table that fits into a single column of a two-column layout. 
Note that REV\TeX~4 adjusts the intercolumn spacing so that the table fills the
entire width of the column. Table captions are numbered
automatically. 
This table illustrates left-, center-, decimal- and right-aligned columns,
along with the use of the \texttt{ruledtabular} environment which sets the 
Scotch (double) rules above and below the alignment, per APS style.
\begin{ruledtabular}
\begin{tabular}{lcdr}
	\textrm{Left\footnote{Note a.}}&
	\textrm{Centered\footnote{Note b.}}&
	\multicolumn{1}{c}{\textrm{Decimal}}&
	\textrm{Right}\\
	\colrule
	1 & 2 & 3.001 & 4\\
	10 & 20 & 30 & 40\\
	100 & 200 & 300.0 & 400\\
\end{tabular}
\end{ruledtabular}
\end{table}
\clearpage %双栏另起一页
\begin{table*}
	\caption{\label{tab:table3}This is a wide table that spans the full page
		width in a two-column layout. It is formatted using the
		\texttt{table*} environment. It also demonstates the use of
		\textbackslash\texttt{multicolumn} in rows with entries that span
		more than one column.}
	\begin{ruledtabular}
		\begin{tabular}{ccccc}
			&\multicolumn{2}{c}{$D_{4h}^1$}&\multicolumn{2}{c}{$D_{4h}^5$}\\
			Ion&1st alternative&2nd alternative&lst alternative
			&2nd alternative\\ \hline
			K&$(2e)+(2f)$&$(4i)$ &$(2c)+(2d)$&$(4f)$ \\
			Mn&$(2g)$\footnote{The $z$ parameter of these positions is $z\sim\frac{1}{4}$.}
