地下物体磁异常定量解释的许多新方法是基于逐次逼近(此法太冗长)或是仅用了异常曲线的其些特征点。本文提出了由无限延深倾斜岩脉磁场求其参数(即岩脉的宽度、上顶埋深和磁倾角[注])的方法。在野外条件下,计算机能够直接处理磁测数据,且不受任何初值的限制。本方法以富里叶频谱分析为基础,其优越性在于它能将干扰压抑到最低限度。但是需要预先给定磁性岩脉的倾角和磁化倾角值。本方法在一个人工模型和野外实例上进行了试验,并取得了精确可靠的成果。
Many new methods for the quantitative interpretation of magnetic anomaly in underground objects are based on successive approximations (this method is too verbose) or some of the feature points that use only anomalous curves. This paper presents a method of determining the parameters (ie, the width of the dikes, the top-burial depth and the magnetic dip angle [Note]) by infinitely deepening the dike’s magnetic field. Under field conditions, the computer can process magnetometry directly and is not subject to any initial limits. The method is based on Fourier spectrum analysis and has the advantage that it minimizes the interference. However, it is necessary to specify the dip angle and the magnetization dip angle of the magnetic veins. The method has been tested on an artificial model and field examples and has achieved accurate and reliable results.
