【摘要】 我们用电子积分技术测量磁滞迴线的方法,分别测试了NbTi-Cu二组元和NbTi-Cu-CuNi三组元复合线磁体的交流损耗.本文报告了实验结果并把这些结果作了定性的比较.通过比较可以看出:在我们实验范围内,(1)NbTi-Cu二组元复合线磁体的损耗正比于磁体的磁场峰值和励磁速度.(2)NbTi-Cu-CuNi三组元复合线磁体的损耗正比于磁场峰值,但随励磁速度增加而下降.更多还原

【Abstract】 AC losses of NbTi-Cu and NbTi-Cu-CuNi superconducting composite magnets have been measured by means of electronic integral technique. The experimental results are presented and their qualitative comparison are made. It is shown within our experiment range that;(1)AC losses of NbTi-Cu composite magnet are proportional to the peak value and exciting velocity of the magnetic field;(2)AC losses of NbTi-Cu-CuNi composite magnet are also proportional to the peak value of the magnetic field, but decrease as exciting velocity increases.更多还原
