| 摘 要： | 本文根据Bean-London模型计算了超导铌球在迈斯纳态下由于表面穿透深度引起的磁滞损耗.在计算损耗的过程中,将准静态变化的外磁场引起的超导球表层的磁感应强度、感应电流的分布转化为静磁场问题求解,从而方便的计算出磁滞损耗的大小. |
| 关 键 词： | 超导铌球 交变磁场 准静态 磁滞损耗 |

| Abstract: | The hysteresis losses as a result of the penetrating to the surface of the superconducting Nb sphere in the Meissner state are calculated according to the Bean-London model. In the process of the calculation, the magnetic induction and the inducting current at the surface of the superconducting sphere is set as the magnetostatic field problem, which is resulted from the slow change of the external field. |
| Keywords: | Superconducting Nb sphere alternating magnetic field magnetostatic field hysteresis loss |
