| 摘 要： | 超导技术应用中最大的障碍之一就是交流磁滞损耗．文中分析了交变磁场与传输电流不同相时，扁带超导体内的磁场分布情况。根据比恩和基姆模型，建立起等效的磁场分布模型，导出了单位长度的平均磁滞损耗．并给出了磁滞损耗随位相差变化的规律．

| Abstract: | One of the greatest obstacle to the application of superconductors is the hysteresis loss In this paper the magnetic field distribution with phase difference between alternating magnetic field and transport current in a superconducting slab is discussed Two equivalent model of magnetic field distribution are built by using Bean and Kim model respectively. The average hysteresis loss per unit length is derived and the relation betwen the loss and the phase difference are discussed. |
