With this system one can compute the values of free-airgravityanomaly, 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。

The altimetry freeairgravityanomaly 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。

So, instead of'intermediate layer correction', we should adopt freeairgravityanomaly and'topographic trend surface correction', which result in topographic trend surface freeairgravityanomaly.
