\underline{} 是在内容下面划线，不是我想要的，比如 define a rariable like UAI
_math.

There is one problem with this approach, that you cannot search for
"UAI_math" in the PDF file because LaTeX defines \_ to be a drawn
line, not an _ character taken from a font.
I use this solution when I want the _ to be searchable in the PDF file:
\documentclass{article}
%\usepackage{times,mathptmx} % uncomment if prefer Times font
\DeclareRobustCommand\usfamily{%
\fontencoding{T1}\fontfamily{ptm}\selectfont
}
\DeclareTextFontCommand{\textus}{\usfamily}
\DeclareTextCommandDefault{\textunders
