后方交会技术在实际工作中的应用

Application of Resection Technique in Practical Work

本文分析了采用正弦定理解算三角形时出现无解和两解的情况,并从现场实际情况得出结论,凡是现场构成三角形的情况,采用正弦定理解算,除非测量数据有误,都会有解,不会出现无解的情况。对边角后方交会出现无解和多解的情况进行了分析,提出了解决问题的办法。

This paper analyzes the situation of no solution and two solutions appeared when using sine theorem for thecalculation of triangles, and draws conclusions from the actual situation at the scene, the scene usually constitute a tri-angle, the sine theorem of the solution, that unless there is an error in the measured data, there will be a solution whencalculated by sine theorem. The situations of side angle resection without solutions and multiple solutions are ana-lyzed, and a solution to the problem is put forward.
