Calculation of non-equilibrium plasma under air discharges

Number densities of active particles（N2(v6),N2(A3),O2(a1),O and O3） in non-equilibrium plasma were calculated and analyzed under the condition of air discharges with various initial temperatures, reduced electric fields and electron number densities. The results show that, the density of active particles increases with the rising of initial temperature, and the maximum number density of oxygen atom is 4.90×7 , 5.2×1010 and 5.51×1010 cm-3, when the initial temperature is 300, 400 and 500 K, respectively. The density of active particles also increases with the reduced electric field increasing, while the number density of vibrantionally excited N2 varies far less significantly. Moreover, the number
