用Euler反褶积方法反演台湾海峡磁异常

用Ｅｕｌｅｒ反褶积方法反演台湾海峡磁异常，选取的窗口不能大，而决定取舍反褶积解的误差限又不能小，这势必对解的质量有较大影响．为此，不仅用了不同延深的单体模型，而且进行了多体模型实验．结果表明，复杂分布的磁性体，用Ｅｕｌｅｒ反褶积方法确定磁性体的轮廓可能是困难的，但可确定磁性体的水平位置和深度，从而降低了对资料精度和计算参数选取的要求．在磁异常比较复杂的地区．

INVERSION OF MAGNETIC ANOMALY DATA IN TAIWAN STRAIT USING EULER DECONVOLUTION

In this paper, the Taiwan Strait magnetic anomalies have been inverted with Euler deconvolution. The data aperture selected can notbe too large,the acceptance level to determine the quality of the deconvolution solution can not be too small,they all have serious influence on the quality of the solution.In order to get high quality of the solution we use notonly single body models with different length in depth direction, but also multi-body models. The results show that for the magnetic bodies with complicated spatial arrangement, it is difficult exactly to delineate the 3D spatial range in detail, but can determine the horizontal location and depth of the magnetic bodies. So it can decrease the limitation of data accuracy and parameter selection. The interpretation method used here is more useful in complicated magnetic anomaly areas.
