摘要
系统阐述了斜导数方法在边界提取上的优势,在此基础上又提出新的概念——非绝对值斜导数的水平导数,对研究地质体的产状问题有了新的认识。针对这一新方法进行了理论模型设计,指出了斜导数方法存在的问题。运用斜导数方法对某地区重力数据进行研究,得到比较理想的结果。
This paper deals with the advantages of the tilt derivative method in locating boundaries of magnetic and gravity sources and presents a new theory for explaining the inclination of the geological body, which is called non-absolute horizontal derivative of tilt derivative. Some models have been designed to prove the method, and the problems existent in the tilt derivative method are pointed out. The method was employed to explain the gravity potential data of a certain area, with good results obtained.
