引言

由于优快云的Markdown编辑器能轻松地支持 $\LaTeX$ 的公式表示。
因此，今天我们来细数一下 $\LaTeX$ 数学公式的符号表示，以便大家以后随时查用。

1.强调模式

$a^aˇ\hat{a}\check{a}a´a`\acute{a}\grave{a}a¯a⃗ \bar{a}\vec{a}a˙a¨\dot{a}\ddot{a}a˘a~\breve{a}\tilde{a}$ $\begin{equation} \begin{array}{l} \hat{a} & \text{\hat{a}} & \acute{a} & \text{\acute{a}}& \bar{a} & \text{\bar{a}}& \dot{a} & \text{\dot{a}}& \breve{a} & \text{\breve{a}}&\\ \check{a} & \text{\check{a}}& \grave{a} & \text{\grave{a}}& \vec{a} & \text{\vec{a}}& \ddot{a} & \text{\ddot{a}}& \tilde{a} & \text{\tilde{a}} \end{array} \end{equation}$
