3. Basic principles
DRM type thermal conductivity measuring instrument is based on the principle of non-stable thermal conductivity, heating in the experimental material for a short time, so that the temperature of the experimental material changes, according to the characteristics of its change, through the solution of the thermal conductivity differential equation, you can calculate the thermal conductivity coefficient, thermal conductivity coefficient and specific heat of the test material.
