  A model is constructed for a chiral abelian gauge-interaction of fermions and
a potential of three higgses, so that the potential possesses a discrete
symmetry of the vacuum state, which provides the introduction of three
generations for the fermions. For the model including charged currents, a
matrix of the flavor mixing is described, and a phase giving the violation of
CP-invariance is determined. Some approximate relations connecting the values
of mixing matrix to the mass ratios for the fermions in different generations
are derived.
