electric arc lamp

基本解釋

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.
超小功率高強(qiáng)度氣體放電燈電弧管電極極間距誤差要求小，二電極對中要求高，所以采用在電弧管泡殼兩端加縮頸來定位電極。
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.
在超小功率金鹵燈生產(chǎn)中，由于受其體積限制，各種尺寸尤其是電弧管泡殼兩側(cè)縮頸處的內(nèi)徑測量一直是比較困難的。
