英文摘要	Electric fields associated with dipolarization fronts (DFs) have been investigated in the magnetotail plasma sheet using Cluster observations. We have studied each term in the generalized Ohm's law using data obtained from the multispacecraft Cluster. Our results show that in the plasma flow frame, electric fields are directed normal to the DF in the magnetic dip region ahead of the DF as well as in the DF layer but in opposite directions. Case and statistical studies show that the Hall electric field is important while the electron pressure gradient term is much smaller. The ions decouple from the magnetic field in the DF layer and dip region (E + V-i x B not equal 0), whereas electrons remain frozen-in (E + V-e x B = del p(e)/n(e)e).; Astronomy & Astrophysics; SCI(E); 2; ARTICLE; suiyanfu@pku.edu.cn; 7; 5272-5278; 119
