  In this work, we submit the explanation of spectra of the rotary curves of
galaxies on the basis of a vector theory of gravitation without regard to the
dark matter hypothesis. We study the approximation of rotary curves in case of
existing of the medium constant cyclic field by the example of a number of
galaxies. Besides, we obtain the curves of distribution of cyclic fields in the
galaxies, wherein the theoretical and experimental data is equal.
