方程式计数器不起作用

Question

我的方程式参考文献不起作用。方程式右侧的数字没有问题，但参考文献都显示 3.1.2（不存在...）

我用一个简短的例子向你展示我的完整标题

\begin{equation}
 \beta (E) = \frac{1}{T(E)}  = \frac{\partial S}{ \partial E } \approx \frac{S(E+\epsilon) - S(E)}{\epsilon}

  W_0^{i+1}(E) = c \frac{W^{i}(E)}{H^i(E)} = e^{-S_0^{i+1}(E)}

在这种情况下，辅助文件中显示的标签只是空的。有什么想法吗？

Answer 1

必须\label​之内环境equation。虽然你把它放在与 相同的行上\end{equation}，但从技术上讲外部环境。

因此使用类似

\begin{equation}
  % your equation here
  \label{<label>}
\end{equation}
