借標題
\begin{equation}
C(s_{1}, \tau_{1}) & = & \int_{0}^{\infty} C(s_{2} - E)G(s_{2} ,\tau_{2};
s_{1} , \tau_{1}) ds_{2} \nonumber \\ →這是接在上一行後面的
& = & \int_{0}^{s_{2}^{*}} C(s_{2} - E)G(s_{2} ,\tau_{2};
s_{1} , \tau_{1}) ds_{2} \nonumber \\ →這是接在上一行後面的
& + & \int_{s_{2}^{*}}^{\infty} C(s_{2} - E)G(s_{2} ,\tau_{2}; s_{1} , \tau_{1}) ds_{2}
\end{equation}
出現的也是
misplaced alignment tab character &.
請問問題是什麼呢?
謝謝~
