Particle dynamics property of the narrow-gap N_2 during its discharge process

N2 gas discharge fluid model is built by employing the continuity equation-the Poisson's equation and the model is worked out by using finite element method.Thus,obtained is the particle dynamics property of the narrow-gap(5 mm) N2 during its discharge process.Through imitating the N2 gas discharge process,the author finds that the electron avalanche turns into streamer and different initial seed electron will exert different influence on the discharge process.Besides,we can deeply know,from the micro perspective,the discharge process of N2 and other related gases.
