如何在eqnarray中间插入一行文字# TeX - TeX电子排版系统
n*l
1 楼
比如:
a1+a2 = 1 (1)
a3+a4 = 2 (2)
a5+a6 = 3 (3)
summing up above equations, we obtain
a1+a2+a3+a4+a5+a6=6 (4)
我用
\begin{eqnarray}
a1+a2& = &1 \\
a3+a4& = &2 \\
a5+a6& = &3 \\
\textrm{summing up above equations, we obtain} && \nonumber \\
a1+a2+a3+a4+a5+a6=6
\end{eqnarray}
虽然可以, 但是很丑很恶心.
请教有什么好办法吗?
