【摘要】 卫星雷达测高技术的发展，提出了新的边值问题，即测高-重力混合边值问题。为此本文使用了求解边值问题最常用的有限元方法，对测高-重力混合边值问题进行了研究并进行了一定规模的模拟试算。结果表明有限元解法精度是可行的，本文方法对于精确求定广大海洋地区的重力异常和沿海地区的大地水准面具有一定意义。更多还原

【Abstract】 :With the development of satellite altimetry a new boundary value problem of alti-metry-gravimetry has arisen To solve this problem. Finite Element Method (FEM) one of the most often method in solving boundary value problem is adopted in the paper The numerical experiment shows the FEM is a competitive and alternative method among presented method更多还原
