摘要：
Technological and theoretical principles for increasing the accuracy and reliability of the direct measurement of the thermal conductivity of solids are considered. Methods of minimizing the errors in measuring the thermal conductivity by compensating the lateral outflows of thermal energy from a gradient heater and from the side surface of the sample due to heat transfer and radiation are proposed and tested. The optimum procedural and apparatus solutions which minimize the errors of the thermal conductivity of solids, depending on the specific measurement conditions, are determined.
