三角网坐标平差误差方程式列立规律的改进

误差方程式的列立是间接平差的关键环节。但现行“测量平差”教材等文献,对误差方程式的列立规律阐述地不具体、不明确,甚至易发生错误。通过探索研究,本文总结出一套简明、易记、使用方便的规律,这是对三角网坐标平差误差方程式列立规律的重要改进。

Improvement in the Regulations of Error Equation Establishment for Triangular Network Coordinate Adjustment

In indirect adjustment, a key step is the establishment of error equations, but its regulations, discussed in current teaching materials and other documents relating to survey adjustment, are not only inconcrete, unclear but also prone to error. Through the author's research, a set of regulations, which are simple, clear, and easy to remember as well as convenient to use are obtained and summarized in this paper. These contribute to a great improvement concerning the methods of error equation establishment for triangular network coordinate adjustment.
