摘要

基于脉冲电晕汤森德技术，提出了一种易于实现的测量常压电晕放电中载流子漂移速度的方法。该方法还得到电子/离子数比和电子附着系数值的上限。在氮中测得的近似电子漂移速度与已知值一致。此外，在含少量氧的氮中得到的负离子迁移率与已知数据一致。因此，该技术可用于实际气体混合数据的获取。该方法还可用于区分电晕放电中的载流子。

A pulsed corona-Townsend method for measurement of electron/ion number ratios and drift velocities

An easily implemented method based on the pulsed-corona-Townsend technique has been developed to measure drift velocities of charge carriers in a corona discharge at atmospheric pressure. The method also yields the electron/ion number ratio and an upper limit on the value of the electron attachment coefficient. Approximate electron drift velocities measured in nitrogen are in agreement with known values. In addition, the negative ion mobility obtained in nitrogen containing small amounts of oxygen agrees with known data. Therefore, the technique can be used to obtain data for gas mixture of practical interest. The method can also be used to distinguish the charge carriers in a corona discharge.<>
