On the basis of studying theoretical model with the above methods, we have introduced a multiple-cut method for identifying the regional gravityfield and the local field.
在对上述方法进行理论模型考察的基础上，我们提出了一种划分重力区域场与局部场的多次切割法。

Convolution method is a filtering method used to extract fault information from observed gravityfield by adopting known theoretical wavelet.
褶积法是用已知理论子波从重力观测场中提取断层信息的一种滤波方法。
