摘      要：To make accurate measurements,field mills must be calibrated in a known DC electric field space charge in which the quantities can be control1ed.A simulation model of the generation apparatus of the electric field with a space charge has been *** on the combination of the electric field and the transfer of a dilute substances model,the in-fluence of openings in the metal screen was *** results showed that the opening size of the high‐voltage electrode has a great influence on the distribution of the electric field and ion density at the calibration ***,a generation apparatus was designed and developed and ion mobility was *** experimental results showed that ion mobility decreased with an increase in electric field ***,ion mobility tends to be saturated when the electric field reaches a certain critical *** fitting formulas of ion mobility of positive and negative charge are proposed that can be used to predicate ion mobility in a high electric field.
