【摘要】 实验研究了圆柱型空心阴极放电及发光条纹.在氩气环境下测试了放电伏安特性和发光图像.结果表明,放电过程呈现3个明显不同的阶段:随着放电电流增加,负辉区增长,但条纹区总长度、条纹数及清晰度降低;条纹间距随电流增大,但与放电阶段有关;气压的升高导致条纹间距减小.更多还原

【Abstract】 The characteristic and striations in the cylindrical hollow cathode discharge have been investigated experimentally.The voltage-current(V-I) characteristics and the discharge images were measured in argon under different conditions.Results show that the hollow cathode discharge has three distinct stages:As the discharge current increasing,the negative glow grows in length and the striations decrease in amount and resolution.The striation separation increases with the current and related to diffrent stages but decreases with the gas pressure.更多还原
