The inhomogeneous cosmological model with matter in the form self-acting scalar field and perfect fluid is considered. On the basis of exact solutions is considered the evolution of density distribution of a matter in space on a background cosmological expansion by the Universe. Is shown, the first, in such model the equation of a matter state is variable in time and is closely connected to character cosmological expansions. Secondly, it is shown with point of view of the observer the Universe looks as space flat, but with effect of latent mass. This effect consists in that the mass of a perfect fluid by dynamic measurements surpasses the own mass perfect fluid that is explained by presence scalar field (20K).
