摘要：
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 [A(2) Sigma(+)(v' = 1) <- X-2 Pi (v '' = 0)] at 282 nm was used to monitor the ground-state OH radicals.
