随着电算技术的普及,目前都把重磁资料的电算处理(如化极,求导,上下延拓等)作为异常解释的先行步骤.这样作的结果,一方面深化了对重磁场特征的认识,另一方面也为定性、定量解释提供了一些有效手段,对提高重磁异常推断水平也是有益的.但在近几年的实践中,通过电算与实测资料的对比,也发现了一些具体问题值得引起重视,现在提出来供同志们参考,不当之处请予指正.
With the popularization of computer technology, the processing of gravity and magnetism data (such as chemical pole, derivation, up and down extension, etc.) are all taken as the first step in the explanation of abnormality.As a result, on the one hand, But also provides some effective means for qualitative and quantitative interpretation and is also beneficial to improve the inference level of gravity and magnetic anomalies.But in recent years the practice has also found through the comparison between the computer and the measured data Some specific issues deserved our attention. Now they are put forward for reference by comrades. Please correct any inaccuracies.
