\usepackage{widetext}
示例:
\begin{widetext} \begin{equation} \tau_{ij}(t+1)= \begin{cases}\frac{(1-\rho) \tau_{ij}(t)}{X(j)}+\mu\left(\left|D_{\text {worst }}\right|-\left|D_{\text {best}}\right|\right) & i, j \in D_{\text {best }} \\ \frac{(1-\rho) \tau_{ij}(t)}{X(j)}-\mu\left(\left|D_{\text {worst }}\right|-\left|D_{\text {best}}\right|\right) & i, j \in D_{\text {worst}} \\ 0, & \text {other}\end{cases} \end{equation} \end{widetext}
结果如下图所示:
将\begin{table} 和\end{table}改为:\begin{table*} 和\end{table*}
示例:
\begin{table}[htbp] \centering \caption{List of abbreviated names} \begin{tabular}{cc} \hline\hline Names & Abbreviations \\ \hline Huaian Xinya International Business Circle & HXIBC \\ Huayangcheng Community & HYC \\ Shuguang International Business Circle & SIBC \\ Xinya International Building & XIB \\ Golden Eagle International Shopping Center & GEISC \\ Shidai Square & SDS \\ Nanping Yuan & NPY \\ Huaihai First City & HFC \\ Chengde Mountain Villa & CMV \\ Anshe Bridge & ASB \\ Huaihai Garden & HHG \\ \hline\hline \end{tabular} \label{tab:jianxie} \end{table}
改为:
\begin{table}[htbp] \centering \caption{List of abbreviated names} \begin{tabular}{cc} \hline\hline Names & Abbreviations \\ \hline Huaian Xinya International Business Circle & HXIBC \\ Huayangcheng Community & HYC \\ Shuguang International Business Circle & SIBC \\ Xinya International Building & XIB \\ Golden Eagle International Shopping Center & GEISC \\ Shidai Square & SDS \\ Nanping Yuan & NPY \\ Huaihai First City & HFC \\ Chengde Mountain Villa & CMV \\ Anshe Bridge & ASB \\ Huaihai Garden & HHG \\ \hline\hline \end{tabular} \label{tab:jianxie} \end{table}
结果如下:
加在要设置的段落前加一行命令:
\doublespace
加在要设置的段落前加一行命令:
\singlespace
注意:widetext包
上文提到的widetext包可以自己制作,“widetext.sty”,具体内容为:
\NeedsTeXFormat{LaTeX2e} \ProvidesPackage{widetext} %% Mimics the widetext environment of revtex4 for any other class package %% Eg: article.cls %% %% Compiled by: Anjishnu Sarkar %% %% Advantages: %% *) Supports float (eg: figure) in two column format (Advantage over %% multicol package) %% *) One and twocolumn exist on the same page %% *) Flow of text shown via rule %% *) Equal height of text when in two column format %% %% Acknowledgment(s): %% 1.
