To reduce this distance, they focus on creating a carefully structured cathode.
为减少这段距离，他们专注于开发一种结构精密的阴极材料。

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