| 摘 要： | 地球重力场的时空结构与分布特性无论在基础理论研究,还是在地理空间信息建设中都具有重要的意义。地球表面上的观测仪器检测到的只是某一个质点的重力变化(拉格朗日变化),但是理论研究却是基于欧拉引力和引力位场方程进行的。本文基于连续介质力学的基本理论,在改正了文献[5]的一处原则性错误之后,推导出了引力和引力位的Lagrange和Euler增量表达式。本文工作对于高精度地球重力场的时空变化的理论研究具有参考价值。

| Abstract: | It is important to study the space-time constitution and distribution of the Earth's gravitational field,not only in basic theoretical research but also in constructing the spatial information of geography.An analysis of the Earth's gravitational field is usually by utang the equation of gravitational field,but the observation apparatus can only detect the gravitational changes of one point(Lagrange changes).In this paper it has deduced the expression of the Lagrange and Eulerian increment of gravity and de... |
