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.
