高温超导体的磁通动力学性质的研究是超导电性研究的一个重要方面，具有理论和应用两方面的重要意义。

Study of vortex dynamics of high-temperature superconductors is one of the most important and active fields of superconductivity.

另外，多年来人们对高温超导体中涡旋结构性质的研究一直抱有很大的兴趣。

In addition, the vortex structure in high temperature superconductors has attracted significant interest for many years.

在研究中发现霍尔电阻关于温度和磁场的变化曲线满足标度关系，不同高温超导体霍尔电阻随温度和磁场的变化可以用该标度关系来描述。

Then we focus on the anomalous Hall effect in the mixed state of high-Tc superconductors which has been found not only in high-Tc superconductors but also in MgB2.
