![如何使 \begin{align} 计数器重新开始?](https://linux22.com/image/367163/%E5%A6%82%E4%BD%95%E4%BD%BF%20%5Cbegin%7Balign%7D%20%E8%AE%A1%E6%95%B0%E5%99%A8%E9%87%8D%E6%96%B0%E5%BC%80%E5%A7%8B%EF%BC%9F.png)
我先\begin{align}
用文档中的方程式做了一次,然后又做了第二次。但我注意到计数器没有重新开始。
例如,这是第二个等式,它应该重新从一开始。
这是我希望可以重现该问题的代码,但照片就出自于此。

\neg\neg\phi\rightarrow\neg\Box\neg\phi,w_i \mbox{ negation of }1

答案1
除非另有说明,计数器通常具有全局范围。在这种情况下,align
使用equation
计数器,您可以根据需要(重新)设置它:
\begin{align}
<your first alignment>
\end{align}
<some textual content>%
\setcounter{equation}{0}% Restart equation counter
\begin{align}
<your second alignment>
\end{align}
答案2
我完全不推荐这种做法,因为它会让读者感到困惑,而且潜在的超链接会引导读者进入错误的地方:
放入。请注意\setcounter{equation}{0}
,这也会对 产生影响。\align
