在选择可供解释的磁异常时,笔者曾多次遇到过特征很明显,但由于多少受到一些旁侧干扰,而成为不甚完整的异常曲线。此类曲线的解释,尚无现成而简捷的方法。能否找到相应的解释方法,是令人注目的问题。经过对比,本人选择了常用的无限延深薄板模型,作为研究的起点。开初,根据△Z曲线拐点与极值之间的坐标关系,推导了一组γ、h、Ms的反演公式,建立了“拐点—极值分合比解释法”。该方法部分地解决了一些非完整曲线的解释问题。然而在手算的条件下,拐点位置不易准确确定,至使应用上 In selecting magnetic anomalies for interpretation, the author has encountered many obvious characteristics, but due to the number of side-by-side interference, it becomes an anomalous curve. Such curve interpretation, there is no ready-made and simple method. The ability to find the appropriate explanation is an issue of note. After contrast, I chose the commonly used infinitely-delaminated thin-plate model as a starting point for the study. In the beginning, a series of inversion formulas of γ, h and Ms were deduced according to the coordinate relationship between inflection point and extremum of △ Z curve, and the “inflection point - extremum splitting ratio method” was established. This method partially solves the problem of some incomplete curve interpretation. However, under the conditions of calculation, the inflection point position is not easy to determine accurately, to make the application
