  It is shown that inelastic process of the exchange with two massless gluons
is formally equivalent to the process of the exchange with one massive
particle. Thus, using the Laplace's method, a new mechanism of mass generation
in inelastic processes is discovered, which is described by the non-Abelian
gauge theory. Furthermore, it is shown that in the QCD perturbation theory, the
same mechanisms of cross-sections growth take place, similar to the ones
discovered before in the effective scalar theories.
