对于起伏地形条件下直接测得的磁场垂直分量△Z,为了消除地形起伏的影响,便于解释推断,很有必要进行“曲化平”处理.已有许多物探工作者对“曲化平”和场的转换方法做了研究,其中包括冶金部物探公司研究所提出的“曲化平方法”.该方法不但精度较高,而且既能完成向上的“曲化平”计算,也能进行向下的“曲化平”计算.我们在文献的基础上,着重研究了起 In order to eliminate the influence of terrain undulation and facilitate the interpretation and inference, it is necessary to carry out the process of “smoothing and flattening” for the direct component △ Z of the magnetic field measured directly under the undulating terrain. Field conversion method has been studied, including the Institute of Geophysical Geophysical Research Institute of “curved flat method.” This method not only high accuracy, and both to complete the upward “curved flat” calculation can be carried out down The “flat” calculation.We based on the literature, focusing on the study
