The concept of exponential transformations of rectangular Cartesiancoordinates is introduced, showing that a plane curve is more frequently expressed by a unionof four or fewer quadrantal equations defined uniquely in the respective quadrants whichthe curve covers and are therefore quadrant invariant, then the Fermat curve s with someof their geometric properties are formulated.

引入直角笛卡儿坐标幂变换的概念，说明一平面曲线是较经常地用4个或更少的象限方程的并集来表示的；这些象限方程是在曲线所在的各个象限中惟一定义的，因而是象限不变的。然后列出费马曲线的方程，并简述了费马曲线的一些几何性质

Using the theory of area coordinate, arbitrary triangles were transformed into regular triangles. The transverse integration was done on the regular triangle.

利用面积坐标思想，将任意三角形变换为正三角形，使用横向积分方法对正三角形节块进行处理。

In the western mining areas, when from adjustment to restriction adjustment, the original national control points are of low grade, or the points are destroyed and the surface movement is out of shape. thus, there are few control points and the reference frame conversion is a big problem in the western high elevation areas. As a result, this thesis makes a reparable design in accordance with the key problems of holing through survey.

本文就利用GPS技术测设地面近井点的网形布设、观测方法、数据处理作了相应阐述；并对由无约束平差到约束平差时，西部地区可能遇到在矿区分布的原有国家控制点往往只有低等级点，或点位遭破坏、地表移动变形等可能使可用控制点很少的情况、以及西部高海拔地区坐标系统变换问题，提出了针对贯通测量的关键问题应对方案。
