摘要：
Images are taken to study the influence of applied voltage and O-2 or H2O vapor content on discharge evolution and jet length of atmospheric pressure plasma jet in Ar/O-2 and Ar/H2O mixtures. Three discharge modes of corona, dielectric barrier discharge, and jet with the increase of applied voltage are identified, and the breakdown voltage and jet generated voltage are different for O-2 and H2O adding. The jet length decreases with the increase of O-2 and H2O content, and this may be due to their quenching effect on excitation and ionization particles.
