ABSMACT: The study consists of a two-part investigation of dissipative effects on
the structure of compressible gas flowo in part (1)j using Navier-Stokes equations
and the laws of thermodynamics, asymptotic equations are derived satisfying a flow
of the "short wave" type propagation in viscous heat-conducting gas, The flow is
assumed to be 2-dimensional and unsteady. A, moving system of coordinates is
introduced, x to y T~t, t to where'
