Consideration is given to an elastic medium with a finite 
time of relaxation of the heat flux; the equations of motion of the 
medium are written in components of the tensors of force and couple 
stresses. Using the general theory of characteristics the explicit 
formulas for determination of the velocities of propagation of the 
discontinuity surfaces are obtained and the equations of the 
characteristic surfaces are derived.
