事实证明，常压等离子体释放的多种自由基可以对材料进行有效的表面处理和改性。然而，在材料表面处理中，测量大气压等离子体产生的自由基的方法及其反应机理还不清楚。利用激光诱导荧光系统成功地测量了非平衡大气压直流脉冲放电等离子体射流中OH自由基的分布。用282 nm处的OH跃迁[A2 <$+（v' = 1）<$X2 <$（v”= 0）]监测基态OH自由基。
It has been proven that many types of radicals released from atmospheric-pressure plasma can provide effective surface treatment and modification of materials. However, the method for measuring radicals generated with atmospheric-pressure plasma and their reaction mechanisms have not become clear in material surface processing. The OH radical distribution was measured successfully in nonequilibrium atmospheric-pressure dc pulse discharge plasma jet by use of the laser-induced fluorescence system. The OH transition [A2Σ+(v' = 1) ← X2Π(v" = 0)] at 282 nm was used to monitor the ground-state OH radicals.
