| 摘 要： | 本文首先论述了利用病态方程组奇异值分解法来改善求解等效源的方法,在此基础上试算了过去难以实现的变磁化方向及小磁化倾角时的化磁极,进一步探索用等效源法解决重磁反演问题的可能性。通过理论模型和实际资料的计算表明了方法的正确性。

| Abstract: | The technique for improving the evaluation of equivalent source by meansof resolving singular values of ill-conditioned system of equations is discussed inthis paper, and on such a basis, reduced to the pole is tentatively performedunder the condition of varying magnetic directions and small magnetic dips,which has been formerly considered to be extremely difficult. Moreo ver, it makesa further approach to the possible solution of the problem of gravity andmagnetic inversion by equivalent source method. The theoretical model andcalculations for ore’ districts all demonstrate the correctness of this technique. |
