Abstrakt: The simplification of the procedure of setting up the equations of crystal lattice vibrations in terms of dependent natural vibration coordinates by choosing a rational coordinate system and introducing symmetrical linear combinations of coordinates, thus reducing the excess of coordinates, is considered. Vibrations in a plane square lattice are used to illustrate the method.
