本文叙述了利用稳态纵向热流法原理建立的金属材料低温导热系数测定装置。该装置适用于液氦至室温温区,本装置采用美国国家标准局的电解铁标准参考材料进行检验,实验结果与N·B·S 给出的数据很好的相符。
This paper describes a low temperature thermal conductivity measuring device for metal materials established by the steady-state longitudinal heat flux method. The device is suitable for liquid helium to room temperature. The device uses the standard reference material of electrolytic iron of the United States National Bureau of Standards for testing. The experimental results are in good agreement with the data given by N · B · S.
