研究了放电后与各种分子氮激发电子态耦合的电子动力学。结果表明，电子能量分布的高能 ()5 eV) 部分因电子超弹性碰撞而强烈增强，并且各种振动电子态的贡献在各自的阈值处出现峰值。放电后状态的弛豫主要取决于主动放电中各种电子振动态的激发程度。结果表明，能量池反应在确定 A 3 Sigma +u、B 3 Pi g 和 C 3 Pi u 态的振动分布中起主导作用。
Kinetics of electrons coupled to those of various molecular nitrogen excited electronic states in post-discharges is studied. Results show that the high-energy ()5 eV) part of the electron energy distribution is strongly enhanced by electronic superelastic collisions, and contributions from various vibronic states appear as peaks at their respective thresholds. The relaxation in the post-discharge regime depends critically on the degree of excitation of the various vibronic states in the active discharge. It is shown that energy pooling reactions play a dominant role in determining the vibrational distributions of A 3 Sigma +u, B 3 Pi g and C 3 Pi u states.
