摘要
通过对近几年的大量试验数据统计分析．得出在一定作业条件下，中间法EDM精密三角高程测量可以代替二等几何水准测量的可行性及其采取的相应措施，同时探讨了该法作业中涉及的一些问题。
Through the statistics and analysis of a large amount of experiment data in recent yeare, it is concluded that the Level II is possible to be replaced by EDM trigonometric height with balaneing the distances to fore point and to back point under suitable working conditions.The corresponding measures adopted in this method are given in the article and some relating problen are also discussed here.
