摘要

NO作为救治急性呼吸衰竭综合征的新方法而受到关注。空气中的电弧放电可以产生NO。为满足NO医疗应用对NO2和NO2/（NOx）尽可能小的要求

实验采用负脉冲电弧放电

重点研究了电极间距、放电频率和电极极性等参数对NO和NO2浓度的影响。结果发现:NO2/（NOx）的比值在某电极间距范围内有一个最低值

NO和NO2浓度随电极间距和放电频率的提高而增加

电极极性对NO2/NOx比值的影响不明显。可以通过对放电条件的选择与组合

达到降低NO2浓度和NO2/（NOx）比值的目的。

Abstract

As a new approach to treat acute respiratory distress syndrome

NO has recently received more attention

which may be generated by arc discharge in air. The concentration of NO2 and the ratio of NO2 /（NOx）must be as little as possible for the medical application of NO. In this paper

NO is generated by negative pulsed discharge between needle and plate electrodes in dry air at the atmospheric pressure. Some important parameters affecting concentration of NO and NO2 have been investigated. These include the distance between electrodes

the pulsed discharge frequency and electrode polarity. The results show that the ratio of NO2 /（NOx） is the lowest within one of the distances between electrodes and the concentration of NO and NO2 increases with raising of frequency and increasing of the distance between electrodes. Electrode polarity unconspicuously affects the ratio of NO2 /NOx. The concentrations of NO2 and the ratio of NO2 /（NOx） could be decreased by the choosing and combination of discharge conditions.
