| Abstract: | The influence of pulse heating duration on measurement and the f coefficient in the formula for calculating thermal parameters in the experiment of plane source-pulse transient method are theoretically analyzed. The corresponding experimental apparatus is established and some commonly used materials are measured in practice. The uncertainty of thermal conductivity, thermal diffusivity and volume heat capacity measurement are systematically analyzed. |
