本文研究了相互作用电子系统中自发电流不存在的布洛赫定理。结果表明，该定理仍然适用于有电流感应磁场的系统。本文还详细讨论了在自发表面电流中的应用。我们的结果排除了最近提出的具有表面流和有限总电流的d波超导的可能性。
We study the Bloch theorem which states absence of the spontaneous current in interacting electron systems. This theorem is shown to be still applicable to the system with the magnetic field induced by the electric current. Application to the spontaneous surface current is also examined in detail. Our result excludes the possibility of the recently proposed d-wave superconductivity having the surface flow and finite total current.
