摘　　要：采用15′×15′网格离散化手段对均质旋转对称椭球体产生的引力位场进行了数值模拟计算,在相对精度优于10-4的水平上,验证了引力位虚拟压缩恢复法以及重力场虚拟向下延拓法的可靠性和有效性。Discrete approach with 15＇× 15＇ grid is adopted in order to numerically simulate and calculate the gravitational potential field generated by the homogeneous rotation-symmetric ellipsoid, and it is verified that the method, the fictitious compress-recovery and the fictitious downward continuation of the gravitational field, is reliable and valuable at the relative accuracy level higher than 10^-4,

关 键 词：虚拟压缩恢复 虚拟向下延拓 均质椭球体引力位 模拟试验检验
