摘要：

A long atmospheric-pressure plasma column confined in a dielectric tube is generated in argon with use of a single-electrode configuration driven with a sinusoidal power supply operating at 45 kHz. The electrical characteristics are investigated by means of measuring voltage-current and voltage-power curves at two gas flow states, turbulent and laminar. The gas temperatures of plasma discharge at various gas flow rates are determined by the spectroscopic analysis of OH A-X spectrum. The discussion about effect of gas flow on electrical discharge characteristics is presented and it is found that the heat removal by gas flow plays the most important role in determining its electrical characteristics.
