摘要：

This study developed a relatively simple method of measuring thermal conductivity that eliminates the methodological difficulties. To determine thermal conductivity, two short rods made of the same material, whose ends have the ambient temperature, are heated by electric current (in vacuum) until the same temperature T//m is obtained in the central normal section of each specimen. The rods have the same cross section but different length. The thermal conductivity is determined by the mathematical relationship between the electrical resistivity and cross-sectional area of the specimens, taking into account the current and the temperatures of the specimens.
