摘要
在低纬度地区，为了克服化向地磁极的不稳定性，将有限截断的化极滤波因子和上延滤波因子相结合进行化极。消除了南北向条带状异常的干扰，同时压制了高频异常的干扰，得到了高质量的化极效果。
In order to overcome reduction to the pole′s unstability in low latitude region, the combining a truncated reduction to the pole′s filter with an upward continuation was used. Using the method can suppress banded magnetic interference in north-south direction and the interference of high frequency composition. At the same time, the method can get high quality reduction to the pole results.
