13. 混合编辑

公式中插入文本\mbox{}：

\[y = x^2 \; \mbox{(二次函数)} \]

公式中插入空格\, \; \quad \qquad间隔依次变宽：

代码	渲染	说明
`ab`	$$ ab $$
`a\,b`	$$ a\,b $$
`a\;b`	$$ a\;b $$
`a\quad b`	$$ a\quad b $$
`a\qquad b`	$$ a\qquad b $$

插入编号：
使用\tag指令指定公式的具体编号，并使用\label指令埋下锚点。

如y=x^2 \tag{1.5a} \label{eq:test}：

\[y=x^{2} \tag{1.5a} \label{eq:test} \]

引用编号：
使用\eqref指令引用前面埋下的锚点，\eqref{eq:test}将显示为：
\[\eqref{eq:test} \]
