Abstract:By analyzing the amplitude and phase spectrum of the harmonic waves produced by heat wave transmission,the heat conductivities of good conductors with heat loss were obtained.The instruments were simplified,the system errors were eliminated,and the effects of heat convection and radiation could be ignored.
Keywords:dynamic measuring method  heat conductivity  heat loss  good conductor
