我们推导出 T=0 时涡流穿过带电超流体所引起的电场的伽利略不变表达式，该表达式适用于从脏极限到超净极限的任何超导体。分析了涡旋周围不同区域对平均电场和电荷分布的贡献。结果扩展到中性系统，其中化学势在带电情况下取代了静电势的作用。将带电和中性超流体中涡旋质量的不同贡献放在一起进行比较和讨论。 {版权} {ital 1998} {ital 美国物理学会}
We derive a Galilean invariant expression for the electric field induced by a vortex moving through a charged superfluid at T=0, which holds for any superconductor, from the dirty to the superclean limit. The contribution of different areas around the vortex to the average electric field and to the charge distribution is analyzed. The results are extended to a neutral system, where the chemical potential takes over the role of the electrostatic potential in the charged situation. Different contributions to the vortex mass in charged and neutral superfluids are brought together for comparison and discussion. {copyright} {ital 1998} {ital The American Physical Society}
