MEDIUM WITH ALLOWANCE FOR THE RELAXATION
TIME OF THERMAL DISTURBANCES

Formulas for the coordinates of points of a cubically 
anisotropic thermoelectric medium, which determine the geometry of 
wave fronts excited by a lumped disturbance source, have been obtained. 
The three-dimensional fronts of a quasilongitudinal modified elastic 
wave, a modified thermal wave, and quasitransverse elastic waves propagating 
in lead have been constructed.
