Therefore, the deep sources producing the regional anomalies should be understood during using the method to process observed gravity anomaly.
因此，应用本方法处理实测重力资料，必须首先了解引起区域重力异常的场源情况。
By using 3-d gravity forward calculation, we obtained the deep gravity anomalies of Tai-wan from its Bouguer anomaly. Its depth corresponds to the lower crust.
经过三维重力正演计算，我们从台湾的布格重力异常中求得了深部重力异常，其深度相当于地壳下层。
The favourable conditions of the deep development of the earthquakes are:the gravity anomaly gradient belt;
深部孕震的有利部位是：区域性重力梯级带；
