In area of low magnetic latitude, however, reduction calculation over large data area and geologic interpretation of the resulted data are still in its infancy.

但在低磁纬度地区，作大面积化极换算并进行地质解释的工作仍处于探索阶段。

In order to overcome the unstableness of reduction-to-the-pole at low and intermediate latitude, there are varieties of methods of reduction-to-the-pole.

为了克服在低纬度区磁化极不稳定的问题，出现了多种磁化极方法。
