摘　　要：详细介绍了一种确定三维网中相对稳定点组的方法。依据一组点间的几何关系是否保持不变可以判别这一组点是否相对稳定。文中阐述了该方法的实施步骤，且给出了一个实例，证明了方法的有效性。In the deformation analysis and coordinate transformation, it is usually necessary to find the relative fixed points as the reference datum. A method of determining the relative stable points in three demensional network is presented, in which the stability of points is depended on the invariance of geometric relation among points. A practical sample given in the paper confirms the effectiveness of the method. The method could be also used to distinguish the GPS points whether to locate at a same tectonic block.\;
