4 示例：

5 设 \(a,b\) 是不全为零的整数，则存在整数 \(x,y\), 使得 \(ax+by=gcd(a,b)\).

5.1 证明：

设取 \(x_0\), \(y_0\) 时，\(ax+by\) 的最小整数是 \(s\).即 \(ax_0+by_0\) = \(s\)

因 \(gcd(a,b)|ax_0\) ， \(gcd(a,b)|ay_0\)

所以 \(gcd(a,b)|s\) \(.........(1)\)

设 \(a=qs+r(0\le r\le s)\)

\(r=a-qs=a-q(ax0+by0)=a(1-qx0)+b(-qy0)=ax+by\)

因为 \(s\) 是最小整数，\(\Rightarrow r=0\)

所以 \(s|a\),同理 \(s|b\)

\(\Rightarrow s|gcd(a,b)\) \(..........(2)\)

由 \((1)(2)\) 可得 \(s=gcd(a,b)\).

证毕。

The Pythagorean theorem is: \[\begin{equation} a^2 + b^2 = c^2 \label{pythagorean} \end{equation}\] Equation \(\eqref{pythagorean}\) is called `Gougu theorem' in Chinese.

9 LaTeX 的正则替换

9.1 说明

其中 trigger 字段指定触发字符，replacement 代表将触发字符替换后的字符，option 是选项，t 代表文本模式，m 代表 latex 模式，r 代表正则模式，A 代表自动触发。文本模式指仅在正文中触发，latex 模式指仅在 latex 块中触发——$ 包裹的部分，r 是使用正则表达式，w 代表词边界，仅当触发字符前面（和后面）有单词分隔符时才运行此代码段。\(0\) 代表光标跳转的位置，\([[0]]\) 代表正则表达式替换的位置。 Description 是片段描述，可选，priority 是优先级，当有多个同样的触发字符时，优先级高的会优先触发，默认是 0 优先级。

以第一个片段为例：指明 $ 为触发字符，将字符替换成，替换后光标在两个 $ 符号中间，option 中的 t 代表文本模式，不会自动触发。
