<blockquote>
The reasons for a necessity of taking into account 3-body interactions in a
description of a behaviour of real fluid near the liquid-gas critical point
are regarded.

The influence of 3-body forces on some properties of argon
is estimated. Particularly, a way of taking into account 3-body
interactions in the theory of liquid-gas critical point by the collective
variables method is considered.The effects of 3-body forces on the structure
functions of the reference system,as well as on the value of 3-rd virial
coefficient and on the thermodynamical properties of some simple real system
are investigated. Using the generalized mean field theory, the critical
amplitudes for some thermodynamic functions of argon are calculated.
