Abstract. Two new methods of measuring the thermal conductivity of solids are considered, based on the use of absolute and relative measurements of the initial thermal quantities that determine the value of the measured parameter. In the presented methods, the influence of traditional negative factors of experimental technique on the accuracy of the results obtained is maximally reduced.
