【摘要】 评论了前人对ＨＩＤ灯高频运转时发生的电弧不稳定现象的论述。对 放电周期性加热气体、使粒子振荡并产生压力波、当该波与放电容器谐振形成驻波 时造成电弧不稳定的所谓“声谐振”论点提出了不同看法。提出了等离子体中离子 振荡是造成电弧不稳定的内在原因的观点。进行的理论分析与前人的实验定量符 合。更多还原

【Abstract】 The descriptions suggested by former specialists about arc instabilities of HID lamps which occurs at high frequency operation are criticized. A diffirent opinion is given on the so called "acoustical resonances" that the discharge heating gas in arc vessel with frequency of input power, results in partiodic particle oscillations and pressure wave, then influences the stability of arc. A view that the ion oscillations in plasma causes arc in stable is suggested. Theory analyses of ion oscillations agrees very well with experiment results reported in reference papers.更多还原
