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。

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。
