摘　　要：The characteristics of radio frequency atmospheric pressure discharge in nitrogen and oxygen mixture gases are investigated by using a one-dimensional fluid model.The model consists of equations of particle continuity,Poisson's equation,and the electron energy equation.The effect of the concentrations of O_(2) in N_(2) on the discharge characteristics is analyzed.The results show that when the concentration of O_(2) in N_(2) is less than 12%,as the amount of O_(2) grows,the electron density and the N4+ion density decrease;the main negative particles are electrons.When the concentration of O_(2) in N_(2) is greater than 12%,the electron density and the N_(4)^(+) ion density increase with the increasing admixture of oxygen;the main negative particle is the O^(-) ion.Moreover,the O^(-) ion density,the O_(2)^(+) ion density,the electron temperature and the mixture gases electronegativity increase with growth of O_(2) in the range from 4%to 20%and with density of O_(2) in N_(2).
