FIELD: instrument engineering. ^ SUBSTANCE: invention refers to thermal and physical measurements. According the method, the sample is put into vacuum chamber. Electrode is placed near the sample and parallel to its surface. Sample ends are fixed on flexible elements. Sample is heated by passing electric current. For several heating current values there determined is value of current and voltage drop, emission current not less than at three points in isometric section of sample and in the section with temperature gradient. During cooling there determined is emission current depending on cooling time, and as per the received parametre values there determined is electrical resistance, emissivity factor, thermal conductivity and heat capacity. ^ EFFECT: determining thermal and physical properties of conducting solid materials. ^ 4 dwg, 1 tbl |
