From the relation of spatial disturbing gravity and ground gravity data resolution as well as its scope, truncation errors are computed by dividing the gravity anomaly into frequency and resolution.
根据外空扰动重力与地面数据分辨率及其覆盖范围之间的关系，将重力异常分成不同频段、不同分辨率，分别计算了截断误差。
It follows, that where the igneous basement is concealed by a sediment cover, the gravity anomaly may contain a high spatial frequency signal corresponding to the morphology of the buried basement.
意思就是说重力异常中频率比较高的信号可能与沉积层覆盖下的基底的起伏有关。
