摘要
实践表明,位场变换中,观测的结果与计算的结果不同。主要差别是:计算的结果比较光滑、规整及包含近地表的小物体的异常少。产生这种差别的原因有四个:1.计算所用的公式是近似的;2.计算所用数据是起伏现测面上的有限长和离散数据;3.观测数据中的误差;4.观测方法中存在的问题。上述四方面有着内在的因素。
There are differences between the results of potential field transforms and direct measurements. The typical feature is that the computed results seem smoother, more regular and contain less anomalies of the smaller and shallower bodies as compared of the mea0 sured results. There are four factors which are responsible for the difference, namely, 1. the formulas used for computation are mostly approximate, 2. digitized and finite length data measured on uneven surface, 3. the errors in the data and defects in the methods for measuring. There is some interrelationship among these factors.
