【Abstract】 In this paper the mechanism of the thermal contact resistance of solid materials at low temperature and vacuum was introduced in brief. The experimental apparatus using double heat-flux meter method to measure the thermal contact resistance between the rod-shape or thin--disk-shape samples was also introduced mainly. At the same time,the apparatus can be used to measure the thermal conductivity of materials. Finally, the thermal contact resistance of some materials at low temperature and vacuum was proposed.更多还原
