摘要：

It is shown that ion density holes can be generated by a large-amplitude electrostatic ion cyclotron wave on auroral field lines. The rate at which the ion holes are excited is obtained. The presence of ion holes may cause intermittent double layers to be observed in the auroral particle acceleration region. The predicted scale lengths and velocities of the double layers are in agreement with observations.
