摘要
本文描述了用锁相放大器及交流双回路四端法来测量Y·Ba·Cu·O型高T_c超导材料的电阻—温度(R—T)曲线的细节,获得了满意的结果。
This paper states the detail which is to measure the risistance VS. temperature curve of Y·Ba·Cu·O type superconductor in the process of the normal-superconducting phase change by using the lock-in amplifier and the AC double-loop with four-terminal connection of sample. The result of this test is satisfactory.
