摘要
阐述了基于虚拟压缩恢复法的重力场向下延拓,构造了点质量处于内部球内部、内部球外部和在内部球内外各有一个点质量三种点质量异常模型,试验结果支持基于虚拟压缩恢复法的向下延拓。
The downward continuation based on the fictitious compress recovery approach is introduced. As simulation experiment tests,three point-mass models are chosen..a point mass located inside an inner sphere; a point mass located outside an inner sphere; two point masses located separately in the interior and outside of the inner sphere. The simulation experiment results with these three models support the fictitious downward continuation.
