So, instead of'intermediate layer correction', we should adopt free air gravity anomaly and'topographic trend surface correction', which result in topographic trend surface free air gravity anomaly.
为此，应当不做“中间层校正”，而应代之采用自由空气重力异常加上“地形趋势面校正”之结果，以形成地形趋势面自由空气重力异常。
The altimetry free air gravity anomaly can describe structure and basin on continental shelves, and its derived submarine topography contains lots of submarine tectonic information.
测高空间重力异常也可刻画陆架构造及盆地分布，由其推算出的海底地形含有大量的海底构造信息。
With this system one can compute the values of free-air gravity anomaly, Bouguer gravity anomaly and isostatic gravity anomaly.
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。
