读入给定的观测数据文件，在程序中以表格形式显示；程序能实 现两点间高差计算和三角高程路线的近似平差计算(Read in a given observation data file, and show it in program form in program. Calculation of elevation difference between two points and approximate adjustment of trigonometric leveling route)

该程序用于计算三角高程，能够输出三角高程每个点的大致位置，然后进行近似平差(The program is used to calculate the triangular elevation, and can output the approximate position of each point of the triangular elevation, and then make approximate adjustment.)

实现了三角高程的近似平差。为了课设做的.(The approximate adjustment of trigonometric elevation is realized. It's for the class.)
