中文摘要:
      基于两点间斜距投影到椭球上的原理,选取研究数据,设计程序,计算斜距归算平距和投影到椭球上弧长之差W,进一步绘制误差等值线,研究随着两点间距离和竖直角变化,根据两点间斜距计算水平距离误差W变化规律。最后,确定该规律对矿山大型设备安装中精密工程测量的影响。
英文摘要:
      Based on the principle of the oblique distance between two points, this paper selects the research data, designs procedure and calculates the difference between the calculated horizontal distance by slope distance and the projection distance to the ellipsoid. Further, the error contour is drawn, and the variation of the horizontal distance error W with the variation of the distance between two points and the vertical right angle is studied. Finally, the influence of the rule on precision engineering surveying in the installation of large scale equipment is determined.
