• There are many measuring methods of thermal conductivity of materials, all of which, however, are the methods conducted in stationary state. In this report, we revolved a wire ring at a certain velocity, heating it by a stationary spot heat source, and measured the thermal conductivity of the material by the relation between the measured value of periodical temperature distribution and that of the theoretical equation, which is analyzed as a problem resulting from the heat source moving along the ring circumference. An advantage of this method is that during measurement the coefficient of heat transferred from the surface of a material can be easily kept constant. Moreover, the availability of this method was ascertained by the experimental results on some materials.
