摘要
Parker-O ldenburg法(PO)界面反演方法的核心算子是向下延拓,由于该算子的不稳定性,限制了PO反演法在重力密度界面反演应用中的发展。利用徐世浙提出的一种精度高、稳定性好的向下延拓的迭代法进行PO反演中的向下延拓,改进了PO反演中的稳定性。把改进的PO反演方法应用到理论模型和莺歌海基底反演中,均取得了较好的结果。
Because of instability, the downward continuation, which is the core operator of the gravity interface inversion by using Parker- Oldenburg （PO） method,restricts the application of the method. This paper introduces a stable and high-precision downward continuation substituting for the intrinsic operator in the Parker formula. Satisfactory results were obtained in the inversion by using the synthetic model and in an application of the method to gravity anomaly over the Yinggehai Sea of the South China Sea.
