自由空间异常

最后结合南海的自由空间异常、布格异常、均衡异常对重力异常进行了初步的地质解释。

Finally , the free air anomaly , the bouguer anomaly , the isostatic anomaly conducted a preliminary geological interpretation .

小比例尺重力自由空间异常图编制方法

Study on compilation method of small scale maps of gravity free-air anomalies

用这个系统可以计算自由空间重力异常，布格重力异常和均衡重力异常值。

With this system one can compute the values of free-air gravity anomaly , Bouguer gravity anomaly and isostatic gravity anomaly .

我们采用二维小波多尺度分解技术，首次对东海及邻区自由空间重力异常进行分解，目的在于获取沉积基底面、莫霍面所产生的重力异常。

In order to obtain the gravity anomalies correlated with the sedimentary and Moho basements , we decomposed the free air gravity anomalies of East China Sea and adjacent regions by using the two dimensional wavelet decomposition technique .

通过对南海重磁数据的重新处理，得到南海西北部自由空间重力异常图、布格重力异常图、磁异常图和化极磁异常图，并对所反映的地球物理场特征加以分析。

On the basis of processing of geophysical data on northwestern South China Sea , map of free air gravity anomalies , Bouguer gravity anomalies , magnetic anomalies , the RTP magnetic anomalies were obtained , and the characteristics of the geophysical fields in this area were analyzed .
