| 摘 要： | 本文介绍了Bi-2223/Ag高温超导带临界电流各向异性的实验测量方法及原理,指出了在不同磁场方向(与超导带面夹角)下,Bi-2223/Ag带临界电流随直流背景磁场的变化规律以及实验应注意的问题.Bi-2223/Ag带材的各向异性决定了其临界电流对垂直于带材表面的磁场非常敏感,这是该带材在高温超导磁体等强电应用方面的不利因素.

| Abstract: | A method for measuring the anisotropic characteristic of the critical current in the Bi-2223/Ag tape is proposed in this paper. The experimental result reveals that the critical current in the Bi-2223/Ag tape varies with the magnitude of external magnetic field under different orientations of external magnetic field applied to the tape surface. The high sensitivity of the critical current in the Bi-2223/Ag tape to the perpendicular component of magnetic field on the tape, which is caused by the high anisotropy of this kind of materials, is a disadvantage for its electric power applications such as HTS magnets. |
