But for weak interference, because the null formed by power inversion array is shallow, the performance for suppressionofinterference is poor.
但对于弱干扰源的情况，该算法形成的零陷不够深，对干扰的抑制有限。

In recent years, on-line monitoring of PD has been a focus at home and abroad, and suppressionofinterference is the difficulty of fault diagnosis.
近年来局部放电监测一直是国内外研究的热点问题，而干扰抑制一直是其中的难点。

The practice proved that the geophone array is favorable tool for suppressionofinterference , having a good results and becoming a basic operation tool in seismic exploration .
