发帖数: 493 | 1 LaTeX will not automatically break a display equation.
However, \usepackage{amsmath} will allow you to break
between display equations.
\usepackage{amsmath}
\allowdisplaybreaks
\begin{gather}
a=1 \\ % LaTeX can automatically break page here
b=2 \\ % or here if necessary
c=3
\end{gather}
Don't use eqnarray. Read the AMS-LaTeX (amsmath) manual
and use its environments instead. (eqnarray has spacing bugs)

发帖数: 493 | 2 The subscript under the second \sum makes you think that
there is extra space, but if you measure it, there isn't (unless
you have loaded other packages that modify the spacing).
If you insist on adjusting the spacing but only for this
equation, try the following. I also recommend the amsmath
package's split environment instead of eqnarray, which has
known bugs in how spacing is calculated.
\documentclass{article}
\usepackage[tbtags]{amsmath}
\begin{document}
Text text text text text text text |

发帖数: 493 | 3 The eqnarray environment has bugs in the way it calculates spacing.
Use amsmath instead:
\usepackage{amsmath}
\begin{equation}
\begin{split}
x &= \text{first line} \\
&+ \text{second line, only one equation number}
\end{split}
\end{equation}
or
\begin{multline}
x = \text{this line flushed left} \\
\text{this line flushed right, one equation number}
\end{multline}
If you have many equations and some of them are long, use
split inside gather or align instead of inside equation. |

发帖数: 3102 | 4 amsmath 的 align/split 等和 \left \right 冲突，特头大。
比如说，我想打：
\left ( blah = \dfrac{\sum_i^N{blah}}{\sum_i^N{blah}} \right)
但是想在 = 处与下一行对齐。这时候 \left 和 \right 就报错了。根据 manual，
改成：
\left ( blah \right. &=
\left. \dfrac{\sum_i^N{blah}}{\sum_i^N{blah}} \right)
这时，左边的括号和`blah' 一样高，右边的和分式一样高 -_-b
如果不想手动设置括号这类 delimiter 的尺寸，想让 latex 自动处理（这个应当
是 latex 的原则吧），该咋办？amsmath 有没有提供类似的命令？ |

You need to load amsmath.sty.
If you need to align the equations, use align or alignat environments
instead of

发帖数: 493 | 19 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).

Don't use "align" in this case.
"align" is for multiple equations with common alignment,
"equation"+"split" is for breaking one single equation
into multiple lines.
You can use "split" inside "align" to break an equation
that is also aligned with other equations. |
