查询词典 X-unit

The electrons are accelerated in the diffusion region near the X point, and the acceleration process can be roughly into two steps : firstly the electrons are accelerated in the z direction due to the electric field, then, they gyrate surrounding the magnetic field with the action of the Lorentz force and get higher velocity in the x direction.
