摘要：
We have constructed LRS Bianchi type I dark energy models with variable equation of state (EoS) parameter in Barber's second self creation theory. We found the equation of state for dark energy omega is time independent and its existing range for derived models is in good agreement with the recent observations of SNe Ia data. In order to obtain a determinate solution of the field equations we consider the special law of variation of Hubble's parameter (Berman in Nuovo Cimento B 74, 182, 1983) which yields a cosmological model with negative deceleration parameter. Some physical and geometrical aspects of the models are also discussed.
