本文试图采用卫星重力资料和一种新的反演方法来研究地幔的横向密度异常分布。
In this paper, we attempt to use satellite gravity data and a new inversion method to study the lateral density anomalies distribution in the mantle.
分析了全球密度异常与板块构造的关系，探讨了全球密度异常分布对板块运动的作用。
The relation between global density anomalies and plate tectonics is discussed. And the action of density anomalies to plate moving is analyzed also.
按照这一模式，纬向重力总是把地球物质从“纬向密度异常高”的地区推向“纬向密度异常低”的地区。
According to this mode, latitudinal gravity always pushes the earth's matter toward the region of"latitudinal density anomaly low"from"latitudinal density anomaly high".
