【摘要】 通过对高温超导带材内部剩余磁场的连续测量,计算机采集数据,并依据超导临界态理论模型计算出临界电流值。为Bi系高温超导带材提供了一种非破坏的连续检测手段,不仅实现了超导带材剩余磁场的实时显示,而且可以给出超导带材均匀性的信息,最终能够计算出整根超导带材临界电流的平均值和不确定度。更多还原

【Abstract】 The trapped magnetic field strength of highTc Bi-2223 tape was measured using Hall probes array method.According to the relationship between critical currentIcand the trapped magnetic strength,theIcof the tape could be easily calculated,this made it possible to realize the non-destruction,non-contact continuouslymeasurement for the long tape.The magnetic field mea-surement can reflect the tape′s original characteristics,such as the uniformity and the flow of the whole tape.The averageIcand uncertainty were calculated basing on the measurement result.更多还原
