摘　　要：研究了气体放电中的等离子体状态形成的规律,通过快速傅里叶变换和Matlab软件对不同间距下的纳秒脉冲波形进行了处理,发现等离子振荡的频率与等离子体的长度成反比,气体放电的间距越大,等离子体振荡的频率越低.The rule of the plasma formation in the process of the gas discharge is studied.The fast Fourier transform and the Matlab software are used to deal with the nanosecond pulse waveform in different spacing,and the conclusion is finally reached that the frequency of the plasma oscillation is inversely proportional to the length of the plasma.The greater the distance between gas discharges exists,the lower the frequency of plasma oscillation is.

关 键 词：气体放电 碰撞电离 等离子体振荡 FFT程序
