摘要
电法勘探中要绘制很多平面图件,但没有用于绘制图件的现成关系式,大部分情况采集到的数据只是一些离散的点,因此必须利用这些离散点拟合一张光滑曲面从而进一步得到等值线图、灰阶图、彩色剖面图等图件.在众多的拟合算法中,加权平均算法是最为理想的一种,它是根据已知的测量数据点集,构造一张通过全部数据点的光滑曲面.该算法可在电法勘探绘图中得到广泛应用.
In electric exploration, many graphs would be drawed, but, ready - made expressions for these graphs are not exist. In most condition, what we can get are some discrete dots. So, we have to use these discrete dots to fit out a smooth surface and then get isoline graphs, gray level graphs, colourful profiles, etc. In all algorithms, weighted average method is the best one, this algorithm is to construct a smooth surface accroding to measuring datas that through all dots. The algorithm has been widely used in electric exploration.
