摘要：The magnetospheric particle drift theory in (U, B) coordinates provides a convenient tool for
analyzing particle drift trajectories from plasma sheet to the inner magnetosphere. However, in this drift
theory, the Alfvén layer for a realistic asymmetric magnetic field model cannot be obtained due to numerical
difficulty. In this paper, we developed a new technique to calculate electron Alfvén layer for Volland-Stern
electrical potential model and dipole + T89 geomagnetic field model. The results show that for realistic
asymmetric field models, the dawn and dusk separators are not in the dawn-du
