摘要
本文介绍采用实用高温超导线材为样品的高温超导实验 ,该实验采用四点法和互感法两种方法同时测量样品临界温度 ,这样既有超导体零电阻特性又有超导体完全抗磁性的实验结果 ,样品架上安装两个测温传感器 ;铂电阻和Si二极管 ,这可使学生了解导体、半导体P N结、超导体的电阻温度特性 .实验对于学生了解超导体特性。
We apply “four point method” and “inducting method” to measure the T C of HTS tape simultaneously. It can view two results: the zero resistance phenomenon and the perfect diamagnetic. We set two sensors (Pt—100,Si diode) on the sample holder for measuring temperature .This is very useful to help student understanding the resistance-temperature behaviour of conductor semiconductor and superconductor.
