你们的基本频率在提升,作为越来越多的这个实相的微妙改变,转变这个密度的你们身体完全的本质。
Ultrasonic Output frequency the majority of the ultrasonic cleaning that is done in industrial applications today USES 40 kHz as a base frequency.超声波输出频率目前大多数工业清洗应用中把40千赫作为基础频率,较低的工作频率。
It is necessary to improve the measuring precision of electric signal's base frequency, which directly influences the precision of its harmonic analysis.由于电力信号基波频率的测量直接影响到谐波分析的精度,提高基波频率的测量精度非常必要。
