发射光谱

Elastic collision and inelastic collision are considered in oxygen molecule, nitrogen molecule by electron impart. The mail simulation results were as follow:(1)The variations of drift velocity and the average energy of electron with the E/N in O2 and N2 are obtained. The number of electrons for excitation, ionization, dissociation and dissociative ionization collision with the E/N and the energy of electron are analyzed emphatically.
