change of the width of scribing line was not distinct when increasing electric current from 100A to 250A.
输出电流在100A~250A范围内，材料表面线宽随电流增大的变化并不明显。
1·By the invention, the reduction scribing waste water is reused and processed, thus leading the water resource to be fully utilized and recovered and saving large amount of industrial water.
减薄划片废水经过本发明回用处理，使水资源充分利用回收，节省了大量工业用水。
