摘　　要：本文讨论了相对论带电费密子(自旋1/2)在均匀旋转电场中的运动,求得了相应的Dirac方程的精确解,还讨论了环境周期变化后的相因子。在缓变场和高能极限下得到一个纯几何的不可积相因子—Berry相因子。这个相因子可以通过实验进行检验。The motion of a relativistic charged fermion (spin 1/2) in a rotating electric field is discussed. The exact solution of the relavant Dirac eqation is obtained. The phase picked up by particle after the environment undergoes a periodic evolution is studied. For a slow changing applied field and in the high energy limit a geometric phase is obtained—Berry phase, which can be measured experimentally.
