无声放电场作用下产生 OH 自由基的实验研究

Experimental Study of OH Radical Generation in Silent Discharge

用一种无声放电方法，使反应器中Ｎ２－Ｈ２Ｏ介质在高频高压电场作用下产生ＯＨ，以促进燃烧反应，抑制碳烟生成，并开发一种追踪化学反应的分子物理测量手段，用共振吸收光谱法测得ＯＨ浓度．

Increasing OH radical concentration artificially in combustion process is of great importance to the inhibition of reductive pollutants such as soot particularly since OH radicals can be conductive to combustion reactions. A silent discharge method of molecular physics which can trace reactions has been developed to produce OH radicals in N 2 H 2O medium in reactor under the condition of high frequency and high volt discharge. Also the OH radical concentration has been measured by resonant absorption spectroscopy. Foundations have been laid for the experimental investigation of soot oxidation effect by OH radicals.
