我们的目的是说明大地测量学的近代发展如何为解决地球动力学的基本问题提供新的工具。例如:1.全球规模的重力场的知识将给出关于地幔中过渡带位置的信息,或关于地核-地幔交界面的地形的资料;2.在地球表面上的高精度定位将允许测量构造板块的位移,同时将对地震预报作出贡献;3.用新技术所确定的极移的分析,将能阐明其阻尼问题,维持这一运动的能源问题以及地核-地幔耦合等问题。
Our purpose is to show how modern developments in geodesy can provide new tools for solving the basic problems of geodynamics. For example: 1. knowledge of a global scale gravity field will give information about the location of the transition zone in the mantle or information about the terrain of the core-mantle interface; 2. high-precision positioning on the Earth’s surface will allow measurement of the structure Plate displacement will also contribute to earthquake prediction. 3. The analysis of the pole shift determined by the new technique will shed light on its damping problems, the energy problems of this movement and the coupling of the core and mantle.
