如果条料没有步距开口槽(正极停止)送进，首次冲压条料送到位置的标记是有必要的。

If stock does not start against a pitch notch (positive stop) a start mark for first hit will be necessary.

阴极倾斜角和极距对导流槽内的电解质流动有一定程度的影响，这为导流槽的结构优化提供了理论依据。

The cathode drained slope and anode cathode distance have some effects on the electrolyte flow. The research will provide theoretical reference for the structure optimization of the drained cells.
