摘要
基于正射方位投影理论,重新分析了测量学课程现行教材中关于"用水平面代替水准面的限度"的论题,得出有益结论,并提出相应的修改建议。
Based on the theory of orthographic projection,this paper reanalysed ＂the extent of using horizontal plane to replace level surface＂,and drew different conclusions.Finally the author put forward the viewpoints and suggestions on the thesis.
