摘要：
The dark energy models with variable equation of state parameter omega are investigated by using law of variation of Hubble's parameter that yields the constant value of deceleration parameter. Here the equation of state parameter omega is found to be time dependent and its existing range for this model is consistent with the recent observations of SN Ia data, SN Ia data (with CMBR anisotropy) and galaxy clustering statistics. The physical significance of the dark energy models have also been discussed.
