t*h
发帖数: 148 | 1 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 | b*********n

我怎么看着一样高呢？

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
