| 摘 要： | 1975年、1976年格林和斯坦利发表了求二维接触面参数的一个方法。本文试图在他们工作的基础上,用空间域滤波来代替格林和斯特利用差商求水平导数和用希尔伯特变换求垂直导数的方法。文中给出了应用空间域滤波计算重、磁异常水平和垂直导数的方法。模型试验证实了理论上的推断。与差商和希尔伯特变换方法相比,优点在于它既能同时滤掉高频干扰,又能使求得的垂直导数和水平导数具有相同的精度,进而提高反演结果的精确度。

| Abstract: | In 1975, 1976, Green and Stanley published a method to determine parameters of two-dimensional magnetic and gravity contact surface. In this paper, instead of using difference division to obtain horizontal derivative and Hilbert transformation to obtain vertical derivative, which were used in Green and Stanley's paper, we apply space domain filter. It is explained in theory that satisfactory result may be obtained. Model computation supports the theoretical derivation. In comparison with Green and Stanley's method. The present method can filter out high frequency noise in the data and get equal accuracy in horizontal and vertical derivatives so as to obtain better results in the inverse problem. |
