高温超导Ⅴ-Ⅰ特性曲线计算机采集系统的研制

The Computer System for Acquiring the Characteristic Curve of High Temperature Superconductor's Voltage-Current

建立了一套高温超导Ⅴ－Ⅰ特性曲线计算机采集系统，实现了对超导样品进行自动测试及方便迅速地对所测样品的数据进行分析处理，有利于高温超导材料临界电流值Ic与国际研究结果的对比．

A computer system was set up to measure and analyse the character curveof high temperature superconductor voltage-current (Ⅴ-Ⅰ) using pulse method.Experiments show that thes system works automatically and rapidly in data processingand analysing. Thus it helps to improve the comparability of critical current measuredby this system with that from overseas work.
