【摘要】 在中低纬度区 ,磁异常化极是磁测资料解释的一项基础性工作。为了克服在低纬度区磁化极不稳定的问题 ,出现了多种磁化极方法。本文提出了阻尼法化极技术 ,该方法具有物理意义明确、操作简单直观、控制参数少等特点。经单个模型和组合模型计算检验 ,表明此法不涉及复杂的参考模型设计 ,也没有复杂的反演过程 ,不仅便于实现 ,而且易于处理大数据量的数据 ,化极结果可以达到目前化极研究的最好水平。更多还原

【Abstract】 At low and intermediate latitude,reduction-to-the-pole technique is basic work in interpretation of magnetic survey data.In order to overcome the unstableness of reduction-to-the-pole at low and intermediate latitude,there are varieties of methods of reduction-to-the-pole.The paper presented the reduction-to-the-pole by damper method.The method is characterized by evident physical meaning,simple and straightforward operation and a fewer control parameters.The method showed after calculating tests by single model and combined model that the method is irrelative to design complex reference model,there is no complex inversion procedure either in the method;the method is facile not only in realization,but also in processing of massive data volume,which can reach the best level up-to-now.更多还原
