摘要
研究了两种不同扭转方式(单向扭转和反复扭转)下高温超导一代铋锶钙铜氧(BSCCO)和二代钇钡铜氧(YBCO)带材临界电流的变化特性。用四线法在液氮、自场环境下测量了带材临界电流随单位厘米扭转角度(即扭转角度与扭转长度之比)的衰减特性和恢复特性,对两种带材在这两种不同的扭转情形下呈现出的变化规律分别进行了总结和比较。
The characteristics of critical current of BSCCO and YBCO tapes were studied under two different torsional ways. The critical current degradation and recovery characteristics of BSCCO and YBCO tapes were measured with four - wire method in liquid nitrogen. In this paper, summaries and comparisons were discussed on critical current degradation and recovery characteristics between two torsional ways and two types of tapes.
