摘要
电弧管启辉实际就是电弧管短暂点亮,一支透明清澈的电弧管往往会在启辉后瞬间从表面上观察到腔体壁变得乌黑,而电弧管点灯时间稍微长一点(一般以电弧管两端电压稳定为准)后关灯却不会出现这种现象。此现象为简单的物理分子热运动学现象,通过对此现象的剖析得出科学的分析结论。
Instant start of the arc tube actually is that the arc tube lights for a short time,and the body wall of a clear arc tube often becomes jet black apparently after instant start.While it lights for a longer time(generally that is based on the stability of voltage on the two ends of the are tube.) before being cut,the phenomenon does not appear.The phenomenon shows simple physical molecules hot motion,and the paper aims to draw a scientific conclusion through the analysis of the phenomenon.
