摘　　要：自然界的闪电就是一种火花放电，在闪电中有多种放电化学反应过程发生，氮氧化物与其它原子分子的放电化学反应是一个重要方面，利用高灵敏度的ＬＭＲ方法研究氮氧化物的火花放电反应．ＮＯ２的火花放电．发生分解反应生成ＮＯ，氮氧化物加水蒸气经放电，反应转变９８％的ＮＯ２，反应转变８０％的ＮＯ，加入氨蒸气经放电，能完全反应转变ＮＯ２，反应转变９０％的ＮＯ．这些也为治理大气污染提供了有用的数据．Nitrogen oxide is one of the main pollutant.In nature lightning is a sparkdischarge.Atmosphere molecules react with each other during lightning.Reaction ofnitrogen oxides with other atoms and molecules is one of many reactions.We studiedspark discharging reaction of nitrogen oxide using high sensitivity laser magneticresonance method in laboratory.NO2 was dissociated to NO after spark discharging.When NO2 reacted with NH3,NO2 was reacted thoroughly after spark discharging.When NO2 reacted with H2O,98% of NO2 was changed after spark discharging.While NO reacted With NH3,90% of NO was changed after spark discharging.When NO reacted with H2O,80%of NO was changed after spark discharging. These data are useful for dealing with atmosphere pollution.
