summary
The method of the rate of thermal conductance measured can be divided into two kinds a steady state law and dynamic law on the whole. This tester adopts the law of steady state to measure the heat conduction coefficient of different materials, its mentality of designing is clear, simple and direct, the experiment method has model nature and practicability. The heat conduction coefficient of measuring the material is an important content in the calorifics experiment.
Tester this by heater, count, show thermometer, count, show time-recorder,etc. make up (adopt the integrated design)
