摘要：
An implicit symmetric difference scheme with the splitting operator and a projective-difference scheme are constructed and investigated for numerical solution of a non-stationary flow of viscous weakly compressible gas. The estimate of error for finite-difference scheme is obtained without taking account of a dependence on the differential solution from parameters compressibility and viscosity of gas. The analogical estimate for a projective-difference scheme is proved, using the analysis of this dependence.
