本文介绍了低温真空下固体界面间的接触热阻机理， 重点介绍一种采用双热流计法既能精确测量圆柱型又能测量薄片型试样间接触热阻的装置， 该装置还能同时测量材料的热导率。同时， 文中给出一些材料在低温真空下的接触热阻值。
In this paper, the mechanism of contact thermal resistance between solid interfaces under low temperature vacuum is introduced. A device that can measure both the cylindrical thermal conductivity and the thermal contact resistance between thin slices by dual heat flow meter is emphatically introduced. The device can measure simultaneously The thermal conductivity of the material. At the same time, the paper gives the contact resistance of some materials under low temperature vacuum.
