一、插入单张图片
\begin{
figure}[H]
\centering
\includegraphics[scale=0.3]{
fig/picture.png}
\caption{
图片说明}
\label{
fig:1}
\end{
figure}
二、插入多张图片
\begin{
figure}[H]
\centering
\subfigure[]
{
\centering
\includegraphics[scale=0.3]{
fig/picture1.png}
}
\subfigure[]
{
\centering
\includegraphics[scale=0.2]{
fig/picture2.png}
}
\caption{
图片说明,(a)第一张图片说明,(b)第二章图片说明}
\label{
fig:1}
\end{
figure}
三、不带序号的公式,且包含换行操作需要加上\begin{gathered}
$$\begin{
gathered}
u(0,y,t) = 6u_ry(1-y) ,\quad v(0,y,t) = 0;\\
u(x,0,t) = u(x,1,t) = v(x,0,t) = v(x,1,t) = 0;\\
T(x,0,t) = 1 ,\quad T(x,1,t) = 0 , \quad T(0,y,t) = 1-y;
\end{
gathered}
$$
四、四周带框框的表格
\begin{
table}[!ht]
\centering
\begin{
tabular}{
|l|l|l|l|}
\hline
~ & $\Delta T = 5t^*$ & $\Delta T = 10t^*$ & 相对误差 \\ \hline
$\left\langle\overline{
N u}_{
\mathrm{
b}, \mathrm{
t}}\right\rangle$ & 2.479 & 2.479 & $0\%$ \\ \hline
$u_{
max}$ & 4.3453 & 4.3447 & $0.014\%$ \\ \hline
\end{
tabular}
\end{
table}
五、常见的三线表格
\begin{
table}[!ht]
\centering
\begin{
tabular}{
cccc cc}%{
|l|l|l|l|}
\hline\hline\noalign{
\smallskip}
~ & $\Delta T = 5t^*$ & $\Delta T = 10t^*$ & 相对误差 \\ \hline
$\left\langle\overline{
N u}_{
\mathrm{
b}, \mathrm{
t}}\right\rangle$ & 2.479 & 2.479 & $0\%$ \\ \hline
$u_{
max}$ & 4.3453 & 4.3447 & $0.014\%$ \\ \hline
\end{
tabular}
\end{
table}
他们的区别在于 \begin{tabular}后面跟的是ccc还是|1|1|
并且对于最顶上的线,要设置成双线,命令为\hline\hline\noalign{\smallskip}
六、添加代码设置命令
%----------------------------------添加代码控制--------------------------------%
\usepackage{
listings}
\lstset{
basicstyle=\footnotesize\ttfamily,
numbers=left,
numberstyle=\tiny,
numbersep=5pt,
tabsize=4,
extendedchars=true,
breaklines=true,
keywordstyle=\color{
blue}\bfseries,
numberstyle=\color{
purple},
commentstyle=\color[rgb]{
0, 0.4, 0}\bfseries,
stringstyle=\color{
violet}\ttfamily\bfseries,
rulesepcolor=\color{
red!20!green!20!blue!20},
showspaces=false,
showtabs=false,
frame=shadowbox,
framexrightmargin=5pt,
framexbottommargin=4pt,
showstringspaces=false,
escapeinside=`', %逃逸字符(1左面的键),用于显示中文
}
\renewcommand{
\lstlistingname}{
CODE}
\lstloadlanguages{
% Check Dokumentation for further languages, page 12
Pascal, C++, Java, Ruby, Python, Matlab, R, Haskell
}
%------------------------------------------------------------------------------%
七、如何在文中引用代码
\begin{
lstlisting}
print("hello world")
\end{
lstlisting}
