在变形测量位移显著性的研究中，两期变形点坐标值的差异并不一定反映点位的移动，它也可能是测量误差引起的；为探明这种差异的产生原因，需要进行位移显著性检验；本文在误差椭圆法点位变形显著性检验的基础上，提出了利用三维误差椭球的新方法，来解决三维坐标变形分析的问题，并用一组数据进行了验证。

In significance analysis study of deformation surveying, the coordinate difference between two epochs may be caused by measurement error instead of point movement. In order to test the reason in this difference, the displacement significance test is required. Three-dimensional error ellipsoid is discussed in this paper to solve the problem of deformation vector significant analysis, and a set of data is used to verify this practically method.
