我想出来的结果是这样:
ab=...
=...
<=...
=...
=...
我用的命令是：
\begin{eqnarray}
ab & = ..
& = ...
& \leqslant\...
& = ...
& = ..
但是出不来上面的效果，后面三行还是比前两行突出来一点点。怎么修改该？
看了上面写的中文manual了，还是找不到答案。
谢谢大侠!

Nod. \begin{align} is better than \begin{eqnarray}, although the latter is
recommanded in the LaTex Bible

这个好像不用usepackage{}吧？不过\begin{align} works!

The eqnarray environment in LaTeX has flawed spacing calculations. The LaTeX
developers decided to keep the flaw as a "feature".
The amsmath package provides more useful alignment environments. For a single
equation split over several lines that is to have only one equation number,
use a combination of the "equation" and "split" environments. For aligned
equations each with its own equation number use the "align" environment (use
\notag to suppress any equation number).
