摘要: To study the production mechanism of atomic nitrogen, temporal profile and spatial distribution nitrogen are measured in atmospheric pressure pulsed positive corona discharge using two-photon absorption laser-induced fluorescence. The absolute density streamer filaments is estimated from decay rate N2 discharge. results indicate that approximately constant against energy. When voltage 21.5 kV, yield produced by an pulse to be 2.9 − 9.8 × 1013 atoms energy efficiency about 1.8 − 6.1 × 1016 atoms/J. energy, while N2/O2 increases with In discharge, two-step process dissociation plays significant role for nitroge...
