III. Basic Principles
DRMThermal Conductivity Test Instruments, based on the principle of non-steady heat conduction, briefly heat the experimental material, causing its temperature to change. By analyzing the characteristics of this change and solving the heat conduction differential equation, one can calculate the specific heat capacity, thermal conductivity, thermal diffusivity, and heat storage coefficient of the test material.
