   The wave mechanism of hydrodynamic parameter pulsation in turbulent flow, and thereof spatial-temporal field calculation technique are suggested. Nature of turbulent boundary layer, laminar sublayer, and vortices are explained. Process of deterministic exciting motion transformation into chaotic field is explored. Distributions of longitudinal and transversal components of velocity pulsations in channel are computed to compare with experimental ones.
