深入学习

1.目录[自动生成]

[TOC](Typora特有)

2. 内联HTML代码[用"<></>"包围]

<div style = "text-align:center">
	<font style = "color : red"> i couldn't use HTML...</font>
</div>

<center>简单的文字居中也可以这样</center>

<u>you should code other programs</u>

markdown 可以当作HTML写

.md文件可直接导出一个网页

下划线可以Ctrl + U

i couldn't use HTML...

简单的文字居中也可以这样 life is short, i need phh.

3. 内联$ \LaTeX $公式[用"$"包围]

(部分编译器会不识别部分符号)

$\LaTeX$

$a^n + b^n = c^n$

$$
%\usepackage{unicode-math}
\displaystyle \ointctrclockwise\mathcal{D}[x(t)]
\sqrt{\frac{\displaystyle3\uppi^2-\sum_{q=0}^{\infty}(z+\hat L)^{q}
\exp(\symrm{i}q^2 \hbar x)}{\displaystyle (\symsfup{Tr}\symbfcal{A})
\left(\symbf\Lambda_{j_1j_2}^{i_1i_2}\Gamma_{i_1i_2}^{j_1j_2}
\hookrightarrow\vec D\cdot \symbf P \right)}}
=\underbrace{\widetilde{\left\langle \frac{\notin \emptyset}
{\varpi\alpha_{k\uparrow}}\middle\vert
\frac{\partial_\mu T_{\mu\nu}}{2}\right\rangle}}_{\mathrm{K}_3
\mathrm{Fe}(\mathrm{CN})_6} ,\forall z \in \mathbb{R}
$$
