Reasonable matching of wafer and wire: the advanced matching of wafer improves average voltage in electric field and current density of wafer corona, which the dedusting efficiency is higher.

板线匹配更合理。先进的板匹配，有效地提高了电场平均电压和板电晕电流密度，收尘效率更高。

The damage size increases with increase of charging current density, but not so apparent at higher current density.

随电流密度增加，氢损伤尺寸增大，但当电流密度较大时，这种增大不明显。

Experimental results show that the solidification structure can be remarkably refined by the application of the higher density pulsed current.

结果表明，高密度脉冲电流可以显著细化其凝固组织。
