The four-velocity of ideal fluid and the calculating formula of Hubble parameter in the standard cosmology are generally used in the discussion on the bulk viscous cosmology in the literatures This paper demonstrates the reasonableness of these disposals by the energy-momentum tensor of bulk viscous fluid and Einstein s equation of the gravitational fiel
