  One the base of Maxwell and Dirac equations the one biquaternionic model of
electro-gravimagnetic (EGM) fields is considered. The closed system of
biquaternionic wave equations is constructed for determination of free system
of electric and gravimagnetic charges and currents and generated by them
EGM-field. By using generalized functions theory the fundamental and regular
solutions of this system are determined and some of them are considered
(spinors, plane waves, shock EGMwaves and others). The properties of these
solutions are investigated.
