超导体

In the experimental research, the levitation force of a HTS above a permanent magnetic guideway was first investigated in the case of zero-field cooling. The hysteresis of the levitation force curve and the interaction between a HTS and the applied magnetic field were explained by the Bean model, and the effect of the measuring precess on the levitation force was further analyzed.

实验研究中，首先研究了零场冷条件下高温超导体在永磁导轨上方的悬浮力特性，借助于Bean模型分析了悬浮力曲线的磁滞特性，阐述了高温超导体与外磁场间的相互作用原理，在此基础上进一步分析了悬浮力测试过程对悬浮力测试结果的影响。

从定性和定量两个方面分析了低温超导体与高温超导体在失超期间产生焦耳热的不同。

This crossover superfluid has many characteristics that are similar to these superconductors," he explains."We hope this superfluid system is easier to understand, and that we can then project that understanding into a better understanding of superconductors.

我希望这种交叉超流体的性质与超导体的性质很相似，我们希望这种超流体系统更容易理解，这样就可以进一步加深对超导体的了解，他说。

采用MTG法及其它类似的方法制备的YBCO超导体的小样品具有很好的超导电性能，但要使YBCO超导体获得实际应用，必须制备超导电性能优异的大块YBCO超导材料，采用籽晶诱导技术是制备高性能大块YBCO超导体的有效方法，因此，制备较大尺寸高质量的〓〓单晶是籽晶诱导技术成败的关键，作者用MTG工艺制备了尺寸达5×5×5mm〓的大块〓单晶，X-ray衍射及X-ray劳埃像法证明MTG法制备的〓晶体具有很好的单晶特性。
