与传统划槽法相比，激光划槽有很多优点。
Comparing with the traditional slotting, the laser slotting has a lot of advantages.
由于激光对划槽材料几乎不产生机械冲力和压力，加上激光光斑小、划缝窄。
Because the laser process has no machine momentum and pressure, and has a small facula and a narrow slot material.
本课题对划槽宽度与扫描速度，电流，脉宽等关系做了深入的研究，总结出各个参数与宽度的经验关系式。
The paper also research on the relation between width and velocity, current, pulse width, and summarize the formulae between width and other parameters.
圆规盘内侧壁设计了直径片转动槽，直径片分两片组装进入转动槽，直径片上设计有滑动阀与转动柄，从而达到精确划圆的目的。
Said diameter plate composed of two pieces is installed in the slot on inner side of compasses' disk. The slide valve and turning handle are on the diameter plate for drawing circle precisely.
