Computer System of Adjustable Increment Size of Pulse Current for Acquiring Characteristic Curve of High Temperature Superconductor's Voltage - Current

建立一套可变电流递增步长高温超导“V—I”特性曲线计算机采集系统,可实现对超导样品进行自动变脉冲电流递增步长测试及方便迅速地对所测样品的数据进行分析处理,且提供了测试过程的实时显示与控制。同时软件界面友好,测试过程操作简单明了,有利于高温超导材料临界电流值I_c与国际研究结果的对比。

A computer system was set up to measure and analyse the characteristic curve of high temperature superconductor's voltage -current( V- I)by means of adjustable increment size of pulse current. The system can acquire data under the mode of automatically adjustable incremen size of pulse current, and work automatically and rapidly in data processing and analysing. Besides, this system provides real - time display and control as well as friendly user interface and easy operating; . Thus it helps to improve the comparability of critical current measured by this system with that from overseas work.
