FIELD: physics; all fields of engineering, medicine, biology. SUBSTANCE: method involves irradiation of substance in liquid phase by infrared rays while varying temperature at arbitrary intervals and recording of irradiated substance absorption spectrum for every chosen temperature. Liquid substance absorption spectrums recorded before and after energy-information impact on substance in liquid phase are converted into digital code, quantitative parameters of these spectrums are found, points are determined within the range of mentioned parameters corresponding to liquid substance absorption spectrums recorded before and after energy- information impact of part under test on this substance, and distance between these points is used to determine energy- information impact of part under test on substance in liquid phase. EFFECT: provision for determining energy-information state of part under test. 2 dwg
