摘要：
Bianchi Type I bulk viscous barotropic fluid cosmological with varying Lambda is investigated. We have also assumed a functional relation on Hubble parameter as H(R) = a(R-n + 1), n > 1, a > 0, H the Hubble constant, R being scale factor and H = (R) over dot/R. The physical and geometrical aspects of the model related with astronomical observations are discussed.
