Basing on hydrodynamics fundamentals we examine the behavior of properties and features peculiar to formation of contact sliding interaction space as isomorphic environment with a changing density caused by emission into surface destruction fractions space. The mathema#tical model describing dynamic behavior of theoretically isomorphic thin sliding contact layer is created for steady motion. Analysis of this model reveals the dependence of solid sliding space#s properties on driving dynamics, space orientation and properties of the multidimensional contact layer environment.

Key words: environment, dynamics, contact, fraction stream, layer.
