摘要：

It is explained that, contrary to the traditional Loeb-Alexandrov model for the negative corona current pulses formation, the more recent streamer-based model admits the existence of a significant free electron current in negative corona discharges burning in ambient air even at distances from the cathode on the order of 1-10 mm. The existence of such free electrons is in a sharp contrast to the commonly held belief that the low-field drift region of the discharge is filled solely with the negative ions. The importance of such free electrons for chemical reactions induced by negative corona discharges is discussed briefly.
