摘要：A long atmospheric-pressure plasma column confined in a dielectric tube is generated in argon with use of a unipolar 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 are also determined by the spectroscopic analysis of OH A-X spectrum.It is found that the gas flow state imposes appreciable influen
