摘要：
A model for the drift of ions under a non-uniform, high-frequency electric field in the drift chamber of a spectrometer of ion mobility increment is developed. For the general dependence of the ion mobility on the electric field strength and the general time-dependence of the separating voltage, we suggest a procedure for calculating of the ion peak form. The shape of the peak for the ion focusing and defocusing conditions has been obtained.
