Consideration is given to the theoretical foundations 
of the method of nondestructive testing of the thermophysical properties 
of solid materials subjected to thermal action from a plane heat source 
of constant strength on a bounded portion of the surface. It has been 
established that the evolution of the thermal process from a bounded 
plane heater will be analogous to the evolution of the thermal process 
in a plane half-space and to the processes in a spherical half-space 
at high values of time.
