摘　　要：目的计算带孔介观超导圆盘中不同涡旋态下超导序参量分布,分析介观孔对超导圆盘涡旋态的影响。方法求解Ginzburg-Landau方程。结果计算了带孔介观尺度超导圆盘中涡旋态的超导电子对密度分布,并与不带孔的介观超导圆盘的情况进行了比较。结论介观孔改变了介观超导圆盘中超导序参量的分布特征。Aim The distribution of the superconducting order parameter at different vortex states is investigated in the mesoscopiC superconducting disks with mesopores, and then the influence of the mesopore on the vortex states is discussed. Methods The Ginzburg-Landau equations are solved. Results The superconducting order parameter distribution of in vortex states had been calculated in the holed mesoscopic disks with mesopores, which was compared with the solutions of the disks without holes. Conclusion The mesopores in the superconducting disks lead to the changes of the distribution of the superconducting order parameter.
