摘要：

We analyze the growth of density perturbations in Newtonian cosmological models with continuous matter creation and obtain the time evolution equation for the mass density contrast. The special case where matter is created by the decay of a cosmological term (LAMBDA) varying as LAMBDA = 3betaH-2 is examined. Constraints on the value of beta from the observed high isotropy of the cosmic microwave background radiation are also obtained.
