挠率、电磁场和内空间

我们在5-维流形中,证明了时-空的挠率与电磁场张量可统一地由一个5-维夫势Aa表示。故电磁场与时-空的挽率可统一地被称为电磁-挠车场．我们还发现”局域化”的内空间的应规产生时-空的挠率;“弯曲”的内空间的度规产生电来场．并在此基础上简单地讨论了内空间、挠率、电磁场与自旋、电荷、电流之间的关系。

Torsion Electromagnetism and Internal Space

We show that torsion of the spacc-time and electromagnetism can be described by a 5-vector potential(Aa ),so the torsion and the electromagnetism can be unitedly called the electromagnetism-torsion field.We also found that the "local"metric of the internal space produces the trosion of the space-time,the "curved"internalspace.produces the electro-magnetism.The relations among the electro-magnetism,torsion,intemal space,spin,electric charse and electric current are briefly discussed.
