Surface discharges with and without a backing electrode using the needle-to-blade of a razor gap were taken. The experiments were performed in dry air of close to O% relative humidity at 101.32 kPa pressure. Acryl resin was used in the sample plates as the electaical insulator. In the results, the current pulse of the discharge without a backing electrode was of a high frequency and the current pulse of the discharge with a backing electrode was of a scattered nature. It was confirmed by the appearance of the frequency of the current pulse that the life time of charges accumulated on the insulator in the discharge using a backing electrode was longer than when the discharge was produced without a backing electrode.}, pages = {41--48}, title = {負極性直流沿面放電の電流*}, volume = {13}, year = {1981} }
