The energy density ɛ and the pressure P of fermion pairs near the homogeneous isotropic singularity are obtained. In general case the contributions of the real pairs and the virtual ones to the ɛ and the P are approximately equal. The contribution of the real pairs is leading when the law of the expansion is a(t) = a1tq, q - 1 << 1. In this case all the matter in the Friedman's cosmological model can be created by a quantum explosion.
