摘要：
The Gibbs-Duhem equation dU + pdV = TdS imposes restrictions on the perfect fluid solutions of Einstein equations that have a one-dimensional symmetry group or no symmetry at all. In this paper, we investigate the restrictions imposed on the Stephani Universe and on the two classes of models found by Szafron. Upon the Stephani Universe and the beta'not equal 0 class of Szafron symmetries are forced. We find the most general subcases of the beta'=0 model of Szafron that are consistent with the Gibbs-Duhem equation and have no symmetry. (C) 1997 American Institute of Physics.
