| Abstract: | 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. |

| Keywords: | downward continuation problem of the gravity field fictitious downward continuation point mass model simulation experiment test |
