摘　　要：讨论了等角投影变换的常系数一般公式及应用模型：墨卡托投影和高斯—克吕格投影间的正解变换及其在高斯—克吕格投影换带中的应用。常系数计算公式优于传统的变系数计算公式，是基于计算机的等角投影变换的最佳模型，它在计算机制图、地图数据库、GIS等领域中有着广泛的应用。本文研究结果的意义在于使等角投影变换更加理论化、系统化和实用化。The paper discusses general formulas for constant coefficient of transformation for conformal projection and applied models-computing formulas for constant coefficient of direct transformation for Mercator and Gauss-Kruger projections and new method of zone trans formation for Gauss-kruger projection based on Mercator projection. Constant coefficient computing formulas are better than traditional variable coefficient computing formulas. Constant coefficent formula for conformal projection transformation is the best model for computer calculation. They could be widely applied in flelds of computer cartography, map databases and GIS, ect.The paper makes conformal projection transformation more theorize, systematize and practise.
