The physical vacuum is filled by the unified objects of the sumicroworld (UOS). They are in groups of four kinds, which move one after another, forming tracts. Tracts move in different directions and with different speeds from each other (in particular being crossed in movement). The basic tracts form knots for exchange connections, which are heavy elementary particles. For maintenance of connections the movement UOS and their groups should be synchronised. The necessity it is the primary reason   of quantization of power processes in the microworld and effects of a relativity.

The reality stated proves to be true by the analysis of a spectrum of masses of heavy elementary particles (HEP), comparison of properties of spatial formations from the basic tracts   with properties of quarks, analysis of a spectrum of a difference of masses of isotopes   at a separation of pairs neutrons, proof of an opportunity to explain generation of a spectrum of masses HEP on the basis of a working hypothesis. __________________________________________

On the shown above circuit the fragment of physical vacuum formed by chains of groups UOS (tracts), and connected among themselves by means of an auxiliary tract B, elementary particles C and D is submitted. In physical vacuum the basic tracts À dominate. The symmetric structures make of sites of tracts "À" a basis of muon and quarks.
