摘要：

neutrinos disengage from of galaxies formation our cosmos (Hu et al., been many attempts to models involving viscous recently studied various field equations for model physical parameters or imposing any extra constraints, as others do. Instead, we will recast the geovering equations for the Bianchi type - V model as adimension less, non-linear, first order, coupling differential equation for cosmological observations h(z), SZm(z), SZA, SZx, and SZ,, then integrate them in parallel to
