   The analysis of effect of three-wave parametric resonance of beam waves in a two-stream relativistic electron beam is carried out. It is found out that in such model the realization of five different on architecture types of parametric resonance interactions is possible. Two from them correspond to explosive instability, two — to process of disintegration with the rise of frequency, one — to super-position of explosive and two-stream instability. Found out increments of growth of waves conditions, in which growth of waves is maximal. Conditions are found out also, in which in a two-stream electron beam the realization of the multiharmonic modes of interaction is possible.
