发帖数: 148 | 3 在一行公式下用下括号注解
结果出来是高高低低的
有没有办法让下underbrace对齐呢？
谢谢 |

Actually I usually do this:
save the following four lines in mymath.sty
\newcommand{\bigstrut}[0]{\vphantom{\big|}}
\newcommand{\Bigstrut}[0]{\vphantom{\Big|}}
\newcommand{\biggstrut}[0]{\vphantom{\bigg|}} % used below
\newcommand{\Biggstrut}[0]{\vphantom{\Bigg|}}
\endinput
then
\documentclass{article}
\usepackage{amsmath}
\usepackage{mymath}
\begin{document}
\begin{equation*}
\frac{\partial N\left(x,y,t\right)}{\partial t}
% use \biggstrut in next line, let \underbrace think that [-MN] i |

我现在希望的是左边的\left\{能够包含矩阵而不包含\underbrace;\underbrace包含矩
阵而不包含左边的\left\{，试了多种方案不行，牛人给指点指点。多谢，Bow。 |

there is a wiki for this question
http://en.wikipedia.org/wiki/0.999...
循环小数写成分数的公式大家还记不记得? 就是酱紫滴:
http://latex.codecogs.com/gif.latex?0.\dot{a_1}\dot{a_2}...\dot{a_n}%20=%20\frac{a_1a_2...a_n}{\underset{n%209s}{\underbrace{99...9}}}
比如, 0.250250250250.... = 250/999
同理, 0.9999999.... = 9/9 = 1, 所以答案是:
等于等于等于等于等于等于等于等于等于等于等于等于等于等于等于等于
等于等于等于等于等于等于等于等于等于等于等于等于等于等于等于等于
等于等于等于等于等于等于等于等于等于等于等于等于等于等于等于等于
等于等于等于等于等于等于等于等于等于等于等于等于等于等于等于等于
等于等于等于等于等于等于等于等于等于等于等于等于等于等于等于等于
等于等于等于等于等于等于等于等于等于等 |

[A, B, C]i
\ /

D
我用了
{\left[ {\begin{array} {*{20}c} A & \underbrace {\begin{array} {*{20}c} B & C
\end{array}}_D \end{array}} \right]_i} \\
但是外面的中括号罢D也包进去了，很难看。有高手可以帮我解决这个问题么？谢谢先。 |

发帖数: 10904 | 15 word 基本没用过，不过上次我用的时候这些都是问题：
给公式加下划线，双下划线，underbrace, overbrace 都可以么？\hat \widehat 都支
持了么？括号尺寸大小有几重？多个 equation 按等号对齐好用么？如何 x-ref 公式
？matrix 好写么？ cases 怎么写？
里？ |

Strut bar - looks nice, doesn't do anything. Ebay has them for $40 for looks
Not sure about Underbrace. K&N intake. if it's the FIPK it sounds great.
Debatable about heat soak at least when the car is not moving. But worth
about $150 on the used market.
Not sure why it has a torque damper.
Tanabe if it's legitimate is a pretty good exhaust. Berk hi flow good
quality.
Stereo system sounds ok. Anvil shifter knob ok.
