| 摘 要： | 在利用发射光谱方法进行电子激发温度测量中,由于N2分子对掺杂原子的淬灭作用,使得计算结果与实际结论有所区别,所以,有必要研究这种淬灭作用,以修正淬灭影响.本文采用发射光谱方法,在标准大气压下,对N2/Ar混合气体负脉冲流光放电激励下氮分子对激发态氩原子的淬灭过程进行了实验研究.其淬灭机理就是处于激发电子态的氩原子与基态...

| Abstract: | In the measurement of electronic excitation temperature using the emission spectroscopy,it has difference between the measure result and the actual behavior because of the quenching influence of nitrogen molecule to doped atom.Therefore,it is necessary to study the quenching coefficient to correct the quenching influence.At normal atmospheric pressure,the quenching process of nitrogen molecule to excited argon atom was investigated under the negative pulse streamer excitation of argon/nitrogen mixture by em... |
