  The mass and charge of a particle correspond to the most diverse form of the
same regularity of the nature of this field. As a consequence, each of all
possible types of charges testifies in favor of the existence of a kind of
inertial mass. Therefore, to investigate these features, we have established
the compound structures of mass and charge. They can explain also the
availability of fundamental differences in the masses as well as in the charges
of Dirac and Majorana neutrinos.
