  Collective behaviors of secondary particles in pp-interactions at 70 GeV/c
are researched. The Two Stage Gluon Model is supposed for describing of
processes with very high multiplicity. It is shown that gluons play the active
role in the multiparticle dynamics. Analysis of multiplicity distributions of
charged, neutral particles and total multiplicity gives the thermodynamic
meaning of these interactions. The mechanism of the soft photon formation as
signature of the quark-gluon system considered.
