一种基于统一引力场表示理论的外部扰动场赋值建模方法

A New Modelling Method of Evaluating Exteral Disturbing Potential Grounded upon the Theory of Unified Representation of Gravitational Field

提出一种新的外部扰动场赋值的建模方法。该方法将场赋值问题纳入统一引力场表示理论的框架，得到的模式具有结构简单、奇性弱的核，并顾及了地形效应，适合低空引力速算。

For a special use a new modelling method of evaluating external disturbing potential is presented in this paper. Being different from classical methods in physical geodesy this method is grounded upon the theory of unified representation of gravitational field. The models created in this way are particularly suitable for a high speed computation of gravitatioal field in low altitude because they take account of topographic effects and have their kernel functions with simple structure and weak singularity.
