摘　　要：根据激光光热法原理,设计了一套低温下界面热阻测量系统,通过Labview操作平台实现对实验温度的精确控制以及对实验数据的自动采集记录。该实验系统能够实现低温下超导带材与导冷材料间界面热阻的测量,为研究直接冷却条件下超导磁体的应用提供实验依据。A measurement System to measure interface thermal resistance in low temperature was de- signed based on laser photo-thermal method, through Labview platform, accuracy control of experimental temperature and auto record of experimental data were realized. The experiment system can realize the measurement of interface thermal resistance between superconducting strip and cooling material, which can offer an experimental accordance to study the application of superconducting magnet under direct cooling condition.
