      The paper gives a very general definition of "physically observable" 1-D symmetry for fast-oscillating solutions and their mathematical description. "One-dimensional" equations are presented resulting from the consistency analysis of previously obtained 3-D equations for multicomponent viscous compressible fast-oscillating gas flow after substitution of "physically 1-D" solutions into them. In original Navier-Stokes equations the component pressures are assumed to be identical. Heat conduction molecular diffusion and chemical reactions are neglected. The component equations of state are arbitrary. The equivalent divergent form of the closed asymptotic equation system of "1-D" fast-oscillating flow for multicomponent gas is considered.
