The control for the Current Source and nanovoltage meter is realized by the IEEE488 bus. The superconductivity is measured based on the zero resistance characteristics of the superconductor. The measurement is of high precision and of high speed. The man-machine interface is direct and friendly. 关 键 词：高温超导体 R-T曲线 虚拟仪器 测试系统 高温超导材料
