中文说明： 一维二度重力异常向上及向下延拓都需要在已知剖面上取值，而且延拓高度应为取值点距的整数倍，因此称为等间距延拓。下面应用Matlab程序实现铅垂台阶向上、向下延拓10m的重力异常与原始异常的对比。 计算铅垂台阶的延拓异常，首先要建立原始异常的函数。铅垂台阶重力异常的表达式为： ∆g=Gσ[πH-h+xln 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报
English Description：
The upward and downward continuation of one-dimensional two-dimensional gravity anomaly need to take values on the known section, and the extension height should be an integral multiple of the distance between the value points, so it is called equidistant continuation. Next, matlab program is used to realize the comparison between the gravity anomaly and the original anomaly when the vertical step extends upward and downward for 10m.
