摘要/Abstract

摘要：

通过测量大气压介质阻挡放电等离子体辐射信号，建立偶极子辐射模型，利用快速傅立叶变换，计算了大气压介质阻挡放电等离子体中离子速度分布。计算结果表明，速度分布偏离麦克斯韦分布，并且随着放电过程的进行，离子速度及相对离子数进行有规律的变化。

关键词: 大气压等离子体, 介质阻挡放电, 离子速度分布

Abstract:

A new method based on fast Fourier transform, is presented to calculate ion velocity distribution by analyzing electromagnetic radiation signal from atmospheric nonequilibrium plasma. This method is based on a dipole model. Results show that the ion velocity distribution deviates from Maxwell distribution over time. The ion velocity and relative ion number fluctuate regularly with time.

Key words: Atmospheric pressure plasma, Dielectric barrier discharge, Ion velocity distribution
