摘　　要：本文首次对图算学在地质工作中的应用进行了初步探讨．并介绍了笔者据其原理绘制的几种多功能地质数据计算图．有了这些计算图，毋需计算器，也毋需查表，便可方便、迅速地进行日常地质工作中的多种计算，如地形坡度计算，断层倾向和倾伏角计算，各种断距计算，各种误差率和百分率计算，样品长度与样品真厚度换算，岩层真倾角与视倾角换算，测定天顶角与投影天顶角换算，钻探、浅井或斜井、平硐等工程进尺与所控制的地层厚度换算，作图垂直比例尺或水平比例尺放大后（或航片影像垂直夸大后）的岩层真倾角与视倾角换算，高差—平距—斜距—坡角换算，等等。The use of several multi-function conversion maps in our routine work are recommended in this paper. These conversion maps are designed to substitute for calculation from, or plotting on, such maps as geological, topographic, engineering etc., without any of calculators,rulers and conversion tables,so as to simplify our calculating and plotting work including calculation of gradient of a slope,calculation of dip and pitch angles of faults,conversion of measures of zenithal angle to its projection, conversion of footage of drill,shallow bored wells,and inclined wells to rock bed thickness,conversion of true dip angle to apparent dip angle of rock bed,and conversion between height deviation,borizontal distance,inclined distance and slope etc.,particular in field.
