In this paper , the authors probe into the characteristics of regional gravity field , residual gravity field , structure of the earth ' s crust and regional tectonics on the basis of the bouguer anomaly map in combination with other geological and geophysical data 摘要本文利用布格重力异常图，结合其它地质和地球物理资料，探讨了青藏高原区域重力场和剩馀重力场特徵及所反映的地壳构造。
It is known from the 1 : 1 000 000 10 ' 15 ' average isostatic gravity map that the northwestern hunan area assumes gravity high , and the other vast areas are basically characterized by zero isostatic anomaly if the local gravity low corresponding to granite is eliminated 摘要由湖南省1 : 100万10 ' 15 '平均均衡重力异常图知，湘西北地方呈重力高；除此以外的广大地区，当消除花岗岩对应的局部重力低外，均衡异常基本呈零值特徵。
According to the characteristics of the gravity anomaly and the geological and geochemical information , 10 faults and four semi - concealed rock bodies ( lanrong - tanjiaao - zhaomianshan , huangping , dongbei and kangkou ) were deduced , which can be regarded as the favorable ore - prospecting sectors 根据重力异常特征，推断了10条断裂，圈定了兰蓉谭家坳照面山、黄坪、洞背和扛口等4处半隐伏岩体；结合地质地球化学综合信息，提出了4处找矿有利地段。
This paper has described several data - processing methods for the gravity anomaly in chengbu area , analyzed the gravity anomaly and its characteristics after the location - field transformation , given a preliminary explanation and deduction of the gravity anomaly and a tentative prognosis of the favorable ore prospecting sectors 摘要介绍了城步地区重力异常数据处理的几种方法，分析了重力异常及其位场转换后的特征，对重力异常进行了初步解释推断。
Based on the regional structure dynamics analysis of the lithosphere imbricate structure in lanping - weixi area , the middle section of three - rivers area ( n26 - 28 ) , the bouguer gravity anomaly of deep structures was completed and the fractal of these faults was calculated . the geology structure model and the elasticoplastic three - dimension finite - element mathematic are described , made and calculated ; and physical simulation was accomplished 针对三江中段n26 - 28兰坪-维西地区的岩石圈正交叠加构造的区域构造动力学分析，进行了深部构造的布格重力异常延拓处理和浅部的断层分维计算，描述、制作计算了地质结构模型、弹塑性三维有限元数学模型和物理模拟。
Using three - dimensional tomographic imaging results of 2 ? 2 ? grid s wave velocity and 15 ' 15 ' grid average gravity anomaly in north china , this paper adopted inversion with constrained least squares method and , as a result , obtained density distribution results of six bedding surfaces in lithosphere of north china 摘要利用华北地区的2 ? 2 ?网格s波速度三维层析成像结果和15 ? 15 ?的网格平均布格重力异常，采用约束最小二乘方法反演，得到了华北地区岩石圈内6个层面上的密度分布结果。
For solving the problems that downward continuation of the space gravity anomaly can not be used in downward continuation of sea surface gravity anomaly , on the basis of prey principle used to compute gravity in the surface - layer of the earth , and with considering the density of sea water and sea bottom topography , two new methods are proposed 摘要针对空间重力异常向下延拓方法不适用于海面重力异常向下延拓的问题，根据珀雷原理求地球表层内部重力的方法、海水密度及海底地形的特征，提出了两种海面重力异常向下延拓的算法。
