METHOD OF DETERMINING HEAT CONDUCTIVITY AND TEMPERATURE CONDUCTIVITY OF SOLID-STATE BODY IN NONSTEADY THERMAL CONDITIONS Russian patent published in 2012 - IPC G01N25/18 

FIELD: physics.

SUBSTANCE: method involves heating a solid-state body through contactless nondestructive thermal action on the surface of the solid-state body using an infrared source, wherein the central axis of the radiator and the solid-state body coincide. The temperature field of the solid-state body and the ambient thermal state are detected by a system of thermal converters. Thermal flux from the solid-state body is detected by a thermal flux density converter mounted on the surface of the analysed solid-state body. Experimental and computational determination of heat conductivity and temperature conductivity of the solid-state body is carried out in the regular thermal condition zone in conditions for cooling the solid-state body with constant ambient parameters.

EFFECT: high measurement accuracy.
