摘　　要：本文介绍的方法,观测元素仅仅是斜边,通过对网的整体平差而获得点的三维坐标,称为测边三维网。文中探讨了布网要求、平差方法及其适用条件。This paper introduces the method of side measuring three dimensional network. The only data to be measured are the lengths of the hypotenuses. The three dimensional coordinates of the points can be obtained from the adjustment of the network. In this paper, the requirements of network arrangement, the method of adjustment and the conditions of its application are investigated.
