The Gross-Pitaevskii equation was generalized for gas of atoms taking into account their electronic structure. It was shown that a wave function of a system of interacting bose-particles being in the one-particle condensate at zero temperature has a form of the Glauber coherent state. With the help of the generalized Gross-Pitaevskii equation polarization properties of the atomic gas in a Bose-Einstein condensate were studied. It was shown that a superfluid system can be spontaneously polarized even if free atoms in stationary states do not have the own dipole moment. Applicability of conceptions under study for analysis of electric phenomena in the supefluid helium was discussed. A perturbation theory for a system of equations of the self-consistent field, describing superconductors with arbitrary type of pairing with account of Fermi-liquid effects, was developed. The Ginsburg-Landau-Gorkov equations for superconductors with s-d-pairing were deduced and analyzed.
