Unlike low frequency data, highfrequency 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 highfrequency 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。

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