潮湿空气中的屏障排放产生大量OH，非常适合处理气体基污染物。为了了解和优化OH的形成和利用，我们以40 /spl mu/m和100 ns的分辨率对OH自由基的时空分布进行了成像。利用Ar/O/sub - 2//H/sub - 2/O（78.5/20/1.5）的流动混合物，我们发现OH只存在于由瞬态微放电形成的85-/spl mu/m半径通道内。在0.1 W/cm/sup 2/的适度功率密度下，这些小细丝的功率密度超过10 W/ sup 6//cm/sup 2//s，迅速填满整个反应堆体积。
Barrier discharges in humid air generate large quantities of OH and are well suited for the treatment of gas-based pollutants. In order to understand and optimize the formation and utilization of OH, we have imaged the spatial and temporal distribution of the OH radical with resolution of 40 /spl mu/m and 100 ns. Using a flowing mix of Ar/O/sub 2//H/sub 2/O (78.5/20/1.5), we have found that OH exists only within the 85-/spl mu/m radius channel formed by the transient microdischarge. At modest power densities of 0.1 W/cm/sup 2/, over l0/sup 6//cm/sup 2//s of these small filaments quickly fill the entire reactor volume.
