文章介绍了高温超导体中的“尖峰效应” ，即临界电流随着磁场增加反而升高的反常现象。

The phenomenon of the peak effect in high temperature superconductors, which is characterized by a fast increase of critical current with increase of magnetic field, is discussed.

因此，对高温超导体的交流损耗及临界电流与应力-应变的关系的研究具有重要的现实意义。

Therefore, the critical current and AC losses of HTS tapes are directly related to tensile stresses and strains, and it is necessary to investigate their correlations.
