 note = {application/pdf, Experiments of the atmospheric discharge, the surface discharges with and without the backing electrode using the needle-to-edge gap have been done in the air at atmospheric pressure. The corona threshould voltage, the breakdown voltage and the corona current have been measured and a photograph of the corona has been taken. It is confirmed that those discharges hold respectively the unique mode of a discharge and oscillographic wave of a corona current.},
