摘要

本研究的主要目的是通过实验确定YBCO超导带的临界电流特性，探讨利用纵向磁场效应提高YBCO超导带的临界电流密度，为未来YBCO新型超导电缆的应用奠定基础。在实验中，我们测量了YBCO超导带在不同温度、不同磁场强度、不同角度下的临界电流值。通过对实验结果的分析，可以为超导电缆的开发提供更多有用的信息。实验结果表明，在低磁场强度下，纵向磁场对临界电流的影响不大，而在高磁场强度下，纵向磁场对临界电流的影响显著。

Longitudinal Magnetic Field Effect in Critical Current Characteristics of YBCO Superconducting Tape

This study’s primary purpose is to identify the critical current characteristics of YBCO superconducting tapes through experiments, discussing the improvement of the critical current density of YBCO superconducting tapes by using longitudinal magnetic field effect to lay foundations to the future application of YBCO new superconducting cable. In the experiment, we measured the critical current values of YBCO superconducting tapes at different temperatures, different magnetic field intensity, and different angles. Through the analysis of experimental results, more useful information can be provided for superconducting cable developers. The experimental results show that the longitudinal magnetic field has a modest effect on the critical current at low magnetic field intensity while it has a conspicuous effect on the critical current at high magnetic field intensity.
