One easy way is to use the following macros:
	\def\down#1{\leavevmode \lower.70ex\hbox{#1}}
	\def\lesssim{\mathrel{\down{$\buildrel < \over \sim$}}}
	\def\gtrsim{\mathrel{\down{$\buildrel > \over \sim$}}}
As you can see, \lesssim generates the symbol "approximately less than"
while \gtrsim generates the symbol "approximately greater than". Note,
they should be used in math mode.

An alternative way is to use AMS fonts, if you have AMS fonts installed
at your site.  Put the following two lines in your preamble,
	\input amssym.def
	\input amssym.tex
then the two above sequence \lesssim and \gtrsim are defined for you.
The bonus is that there are a lot of other neat symbols in AMS fonts.
