The measurements of electromagnetic properties correspond to a larger axial distance and to a greater lateral distance than the measurements of resistivity from current leakage.
与根据电流泄漏进行的电阻率测量相比,对电磁性质进行的测量与更大的轴向距离和更大的横向距离相对应。

Even if a layer of lateral wall damaged, also won't happen dirt danger caused by leakage.
