electric arc lamp

基本解释

The shaped technique of the electric arc tube's shell with neck, which is used in the small power metal-halide lamp, is introduced in this paper.
超小功率高强度气体放电灯电弧管电极极间距误差要求小，二电极对中要求高，所以采用在电弧管泡壳两端加缩颈来定位电极。
On the producing process of the miniature metal halide lamp, due to its bulk, the measurement of its dimensions especially the inside diameter of the necks of the electric arc tube is very difficult.
在超小功率金卤灯生产中，由于受其体积限制，各种尺寸尤其是电弧管泡壳两侧缩颈处的内径测量一直是比较困难的。
