| 摘 要： | 利用局部重力资料确定不完全阶次位系数模型的方法进行研究．首先根据Molodensky边值问题的数学理论和函数展为级数式的一般原理，论述了方法在理论上的正确性；然后根据模型结构，提出了位系数补偿因子，并给出其确定的原则及计算公式；接着构制一个适合局部区域的不完全阶次的高阶位系数模型的方法进行探讨；最后对其精度进行检验．结果显示局部区域2160阶不完全阶次模型对实测垂线偏差二分量的恢复精度分别为±2．56s和±2．61s．

| Abstract: | We firstly propose and investigate a no-whole degree geopotential coefficient model by means of regional gravity data. On the basis of that a compensatation factor for new coefficients is gived, and estimation of the accuracy of new coefficients is also given in the Paper. The deflection of the vertical and of the new model have a RMS discrepancy of ±2.56s and ±2.61s with the terrstrial deflection of the vertical respectively. |
