Because of high-frequency effects (namely skin effect and proximity effect), the current flowing through those windings may be not equally divided among them, resulting in high ac resistance.

由于电磁场的高频效应(集肤效应和邻近效应)，可能导致电流在各并联绕组层中不均分，产生较高的交流电阻。

Unlike low frequency data, high frequency data has the calendar effects and long memory volatility.

与低频数据不同，高频数据通常具有“日历效应”和波动长记忆性。

Experimental results indicate that tiny feeding, low voltage, low duty ratio and high frequency have important effects to increase the truing precision.

实验结果表明最后整形阶段的微小进给量及低电压、低占空比和高频率的电参数对提高整形精度具有重要作用。
