- It is well known that the five-component method is superior to four- component method because the vertical magnetic component H_z can be applied to the determination of formation dip. 众所周知,依据垂直磁场分量 H_z 可以确定地层的倾向,所以五分量的处理手段较四分量的处理更加优越。
- Because of different softness and hardness in crystalline basement of different structural units,the difference reflected on Bouguer gravimetric anomaly map and magnetic anomaly map is significant. 由于各地质构造单元结晶基底软硬程度不同,反映在布格重力异常图和磁力异常图上的差异明显。
