这是我第一个使用双栏排版的期刊，以为很简单。实际有很多细节需要注意。
格式部分
调整公式字号

双栏
模板默认是单栏，需要在开头\documentclass部分加入**iicol**开启双栏。
双倍行距
根据要求，期刊建议在投稿时使用双倍行距。需要在开头\documentclass部分加入**referee**开启双栏。
\documentclass[referee,sn-mathphys-num,iicol]{sn-jnl}满栏间距
使用该语句**[width=\linewidth]**
可以参考下面文章去操作。

引文
我得引文格式是这样**\cite{devriesPopularityBrandPosts2012}**但是莫名其妙报错，经过测试八个bst文件中只有**sn-aps.bst**可以正常识别。
但是**sn-mathphys-ay.bst**``**sn-mathphys-num.bst**无法识别，会报错**Undefined control sequence. <argument> \citeauthoryear**，经过百度需要再开头加一个包。
\usepackage[authoryear]{natbib}abstract
尽量按照模板给的例子**\textbf{Purpose:}**``**\textbf{Methods:}**``**\textbf{Results:}**``**\textbf{Conclusion:}**这个结构去写。
例：
\abstract{
\textbf{Purpose:}This article focuses on the propagation process of social behaviors in social networks and proposes an influence-driven information propagation model to describe the propagation of social behaviors in social networks.
\textbf{Methods:}Initially, it reveals the driving role of personal influence in information propagation and the relationship between personal influence and information propagation.Subsequently, the propagation mode of influence between individuals in the network is studied using propagation dynamics, elucidating the updating rules for interactions of influence between individuals.Ultimately, it explores the feedback loops and coupling mechanisms between information dissemination and influence propagation and how they mutually influence each other.
\textbf{Results:}Extensive experiments are conducted, citing real case studies to investigate the correlation between behavioral propagation and influence propagation in different events.
\textbf{Conclusion:}The results indicate that the change of individual influence in the process of information propagation may change the information propagation, and may also change the influence in the process of information propagation, which proves the validity of the model.
}图例
双栏模板的图例会被文字挤压，所以一般需要**\includesvg[width=0.45\textwidth]{./img/hybird_model.svg}**去固定图片的宽度，保证单栏不被挤压。
当然也可以在使用**\begin{figure*}[bt]**这样的语句保证图例占据一整个板块。
表格
表格有一个小坑，这里记录一下
在其他模板中我是这样写的表格，可以看到加了**{\tblwidth}**这个语句导致一直编译不出来，且不报错。找了半天，发现这个问题。所以写表格要将这句话去掉。
\begin{table}[ht]
\caption{Model parameter setting}\label{tbl1}
\begin{tabular*}{\tblwidth}{@{}LLL@{}}
\toprule
Parameters & Value & Definition \\ % Table header row
\midrule
$N$ & $6000$ & Number of Network Nodes \\
$<K>$ & $3$ & Average degree of the network \\
$\beta_0$ & $3 \times 10^{-2}$ & Initial infection rate \\
$\gamma$ & $5 \times 10^{-2}$ & Initial recovery rate \\
$\omega_F$ & $0.2$ & Emergency data live broadcast rate \\
$\omega_E$ & $0.4$ & Interaction Coefficient \\
$\omega_1$ & $\ln(2)$ & Adjustment Parameter 1 \\
$\omega_2$ & $0.13$ & Adjustment Parameter 2 \\
$\sigma$ & $0.363$ & Influence diffusion coefficient \\
\bottomrule
\end{tabular*}
\end{table}双栏满栏
\begin{table}
\caption{MSE and R-squared}\label{tbl3}
\begin{tabular*}{\linewidth}{@{\extracolsep{\fill}}lll@{}}
\toprule
{} & $MSE$ & $R^2$ \\ % Table header row
\midrule
Real forward case1 & $1.1\times{10}^{-3}$ & $96.67\%$ \\
Real like case1 & $2\times{10}^{-4}$ & $99.33\%$ \\
Real forward case2 & $2\times{10}^{-4}$ & $99.83\%$ \\
Real like case2 & $3\times{10}^{-4}$ & $98.27\%$ \\
\bottomrule
\end{tabular*}
\end{table}单栏满栏
\begin{table*}
\caption{MSE and R-squared}\label{tbl3}
\begin{tabular*}{\linewidth}{@{\extracolsep{\fill}}lll@{}}
\toprule
{} & $MSE$ & $R^2$ \\ % Table header row
\midrule
Real forward case1 & $1.1\times{10}^{-3}$ & $96.67\%$ \\
Real like case1 & $2\times{10}^{-4}$ & $99.33\%$ \\
Real forward case2 & $2\times{10}^{-4}$ & $99.83\%$ \\
Real like case2 & $3\times{10}^{-4}$ & $98.27\%$ \\
\bottomrule
\end{tabular*}
\end{table*}公式
在双栏排版中，如果公式太长会顶出一栏，不仅丑且有问题。
需要手动将公式换行。
