绪言无论在科研或生产工作中,都需要进行大量的数据处理。其中之一为平面数据的等值线图及立体图的绘制,在地质研究各个领域中应用得很广。它是一项非常繁重而又必要的工作。例如,对测得各种地球物理场的数据如重、磁、电等,需要进行图形表示;在地质上对地层、构造、岩矿、地球化学等资料分析,也离不开各种等值线图及立体图形;有些矿产的储量问题,也需要通过等值线图来计算。在资料复杂数据点很多的情况下,用手工
Introduction Whether in research or production work, require a lot of data processing. One of them is the contour map of the plane data and the drawing of the perspective view. It is widely used in various fields of geological research. It is a very heavy and necessary job. For example, the data of various geophysical fields measured, such as heavy, magnetic and electrical, need to be graphically represented. Geologically, data on stratigraphy, structure, rock and ore, geochemistry and the like can not be separated from each other Line drawings and three-dimensional graphics; some mineral reserves, but also need to be calculated by the contour map. In the data complex data points a lot of circumstances, by hand
