要約(英語): Density and temporal behavior of N2(A3Σ+u) metastable, N atom, and NO molecule are measured in pulsed positive corona discharge using time-resolved laser-induced fluorescence (LIF) under atmospheric pressure. In N2 discharge, the N2(A3Σ+u) density is independent of discharge voltage V, while the number of N2(A3Σ+u) molecules produced by the discharge increases with V because the thickness of the streamer increases with V. The absolute densities of N2(A3Σ+u) and N are measured using the decay rate of their densities after discharge by recombination reaction. In N2/O2(2%) discharge, the N density decreases after discharge, while the NO density is approximately constant after discharge because NO production reaction N + O2 → NO + O and its decomposition reaction N + NO → N2 + O are equilibrated. In N2/NO(250 ppm) discharge, it is shown that NO in the streamer is rapidly removed by N atoms within 3μs after discharge, then NO outside the streamer is slowly removed by diffused N atoms.
