摘要
顾及到大地水准面的物理特性,依据其在局部所应满足的数学物理方程,讨论了有限元法逼近局域大地水准面的数学思想,给出了相应的数学模型。
Taking account of the physical characteristics of geoid, according to the equations of mathematical physics of geoid in a local area, the ideas of mathematics of geoid approximation in the area is discussed, based on the finite element method, and a relevant mathematical model is given in the paper.
