摘 要:本文首先分析了剩余异常ΔZ中的虚假成份ΔZA与已知矿体理论场的相关性,然后根据ZA作函数Zf,修改Zf的相关系数,使Zf分别在空间域、波数域和空间——波数域与ΔZ拟合,从而可解出Zf。本方法的优点在于能同时利用场函数的空间域特征和波数域特征,并给出了可靠系数的估计方法。
Abstract: First, this paper analyzes the correlation of false Component (△ZA) in residual magnetic anomaly (△Z) to theoretical anomaly by given bodies.Second, a function Zf can be made in accordance to the property of △ZA.Additionally, Zf can be computed by changing the factors in the function so as to make Zf approximate to △Z in the domains of space, the wave number and the space-wave number respectively. The advantages of this method are that the properties of both space-domain and wave number-domain can be used, and that the method to figure the reliability coefficients may be given.
