FIELD: measuring techniques.
SUBSTANCE: method involves pulsed thermal action from a line thermal source in the plane of contact of the test and reference models. Redundant temperature is measured from one control point in a given time interval, while the initial temperature is controlled at the second point. A discrete mathematical model of direct problem of thermal conductivity and the thermo-physical properties to be determined are found from a series of enumeration of the values of thermo-physical properties in the given identification range.
EFFECT: increased accuracy in identifying the system of thermo-physical properties of hard materials; less time spent measuring.
