通过数值模拟研究了高温超导体沿沿着长度方向的非均匀性对失超行为的影响。采用二维有限差分法（FDM）研究了YBCO薄膜的限流特性，临界电流密度约为10/sup 6/ A/cm/sup 2/，临界电流和温度均降低了1%。已经证明了不同程度的不均匀性的额外的薄导电层的淬火过程中的均衡性能。此外，YBCO薄膜样品进行了实验研究，并与计算数据进行了比较。实验结果与数值模拟结果吻合较好。
Numerical simulations of the combined thermal and electrical behavior have been carried out to study the influence of inhomogeneities along the HTSC length on the quenching behavior. A two-dimensional finite difference method (FDM) has been used to investigate the current-limiting performance of YBCO film with a critical current density around 10/sup 6/ A/cm/sup 2/ on a ceramic substrate, 1% of the length was assumed to have reduced critical current and temperature. The equalization properties of an additional thin conducting layer on the quench process has been demonstrated for varying degrees of inhomogeneity. Furthermore a sample of YBCO film was investigated experimentally and compared to calculated data. The results of the experiments show good agreement with the numerical simulations.
