本文研究了在77 K下，在静态偏置场作用下，高质量YBCO单晶圆片在脉冲磁场作用下的磁通运动。流量Rf作为静态偏置场的函数获得。当磁场增加时，磁通量倾向于更容易移动，大概是由于钉扎力被抑制的事实。还估算了流动电阻率ρf和粘度系数η随磁场的变化。
We have investigated the magnetic flux motion in a high quality YBCO disc induced by a pulsed magnetic field in the presence of a static bias field at 77 K. The flow rate Rf was obtained as a function of static bias field. The flux tends to move more easily as the magnetic field is increased, presumably due to the fact that the pinning force is depressed. The flow resistivity ρf and the viscosity coefficient η were also estimated as a function of magnetic field.
