【摘要】 采用光谱法,研究大气压下氩气/空气介质阻挡放电中电子激发温度随空气含量的变化.放电装置为水电极介质阻挡放电装置,通过氩原子763.51nm（2P₆→1S₅）和772.42nm（2P₂→1S₃）两条谱线相对强度之比计算电子激发温度.实验结果表明:当空气的体积分数为100%～60%时,电子激发温度随空气含量的增加而减小.更多还原

【Abstract】 The variation of electron excited temperature in dielectric barrier discharge（DBD）inargon/air at atmospheric pressure as the function of air concentration was measured by using thespectrum diagnosis.The water electrodes were employed in dielectric barrier discharge.The intensityratio of spectrum lines 763.51 nm（2P₆→1S₅）and 772.42 nm（2P₂→1S₃）was used to estimate theelectron excited temperature.It is found that the electron excited temperature decrease with increasingair concentration when it is in the range of 10%～60%.更多还原
