| 摘 要： | 本文系统论述了利用局部重力数据对已知重力场模型位系数加以改进的理论和方法，问题的实质是重力异常和位系数两类数据的综合利用，文中给出了联合平差和局部积分改进两种方法，重点讨论了局部积分改进的位系数改正数的谱权综合法，并给出了数值试验结果。

| Abstract: | :The theory and method for improvement of the coefficient of a known gra-vity field model using regional gravity data are shown systematically in thispaper. This problem is essentially of combined use of gravity anomalies andpotential coefficients. Two methods, the combined adjustment and the regionalintegral correction, are presented. The frequency weight combined method isdiscussed in datail. |
