The universal search method for pure modes propagation and polarization in crystals, in general piezoelectrics, is suggested. For the problem’s solution the mathematical model of pure modes for elastic waves based on adiabatic state equa-tions for an arbitrary anisotropic medium and its motion equation under the elastic deformations in rotating Cartesian coordinates is constructed. The computer program is prepared to simplify the calculations.
