摘 要: | 本文提出了三度体重磁异常的人机联作校正-迭代反演方法。该方法用二度半组合多边形棱柱体来逼近三度体,从而把三度体重磁异常反演问题转化为二度半体的反演问题;为了消除组合体迭加场的影响,该方法采用了一种校正-迭代技术。理论模型反演计算表明,该方法实际可行。

HUMAN-COMPUTER COMBINATIONAL INVERSION OF GRAVITY AND MAGNETIC ANOMALIES USING CORRECTION-ITERATION |
| |
Abstract: | human-computer combinational inversion method of 3-D gravity and magnetic anomalies is presented in this paper with correction-iteration. This method transforms the inverse problem of 3-D bodies into the one of D bodies by use of D combinational polygonal prisms to approach 3-D bodies. In order to eliminate the effect of stack anomalies of combinational bodies, a correction-iteration technique is adopted. The inversion result of theoretical model shows that this inversion method is practically reliable. |
