一、前言考虑由表层和基底构成的双层构造。一般说来,表层比基底的平均密度要小,所以,如果表层与基底的分界面有起伏,地表布格异常就会出现空间变化。通过布格异常分布计算分界面起伏的方法就是本文论述的双层构造重力解析法。在双层构造解析法中,人们已熟悉的有傅里叶级数法和傅里叶积分法。齐藤和竹内采用计算表的方法也是从傅里叶积分法派生出来的。在这些方法中,把分界面起伏假定为在某一平均深度附近的小幅度的偏移。但是,这种
I. Preface Consider the bilayer structure of surface and basement. In general, the average density of the surface layer than the substrate is small, so if the interface between the surface layer and the substrate has ups and downs, the spatial distribution of the surface cloth will be abnormal. The method of calculating the interface undulation by the Bouguer distribution is the two-layer structure gravimetric method discussed in this paper. In the double structure analytic method, people are familiar with Fourier series method and Fourier integral method. Saito and Takeuchi method of using the calculation table is also derived from the Fourier integral method. In these methods, the interface fluctuation is assumed to be a small amplitude offset near a certain average depth. However, this
