But when scientists started looking at the data overlaid onto a map, they saw dark spots of fuzz, indicating radio frequencyinterference.
但当科学家们开始将这些数据分布在地图上观察时，他们发现了一些模糊的黑点，表示无线电频率的扰动。

In the range of low frequency, Conducted interference is primary pass.
在低频范围内，传导干扰是电磁干扰的主要形式。

The basic idea using array sweeping to suppress harmonic interference is to reasonably design each sub-sweeping frequency band that can reach the goal of elimination of harmonic interference.
