| 摘 要： | 对大气压直流滑动弧等离子体的电参数和发射光谱进行了测量,比较研究了不同气体种类下滑动弧等离子体电压的特性.以氮气滑动弧为例,分析了其在一个周期内电弧电压、电流、电阻和功率的变化特性.通过对电弧电压信号进行快速傅里叶变换频谱分析,研究了气体种类、气体流量和外部电阻值对滑动弧等离子体脉动特性的影响.结果表明随着气流量或外部电阻值的增加,其主要脉动频率变高,电弧周期变小.利用光谱法检测了氮气、氧气和空气滑动弧等离子体的主要自由基种类,并研究了外部电阻值对发射光谱强度的影响和沿电极中轴线在337.1 nm(N关键词：

| Abstract: | The atmospheric pressure dc gliding arc plasma was investigated through its electrical and optical signals. The arc voltages of various gas discharges were compared. The arc voltage,current,power and resistance of a nitrogen gliding arc in one period were studied. Influences of gas type,gas flow rate and external resistor on the gliding arc fluctuation behaviour were studied using FFT spectrum analysis. Increased main oscillation frequency was observed as gas flow rate or external resistance value increased... |
