摘　　要：综合阐述了拟准检定法的原理和特点、研究思路。拟准检定法的关键是如何正确选择拟准观测,文章介绍了初选和复选拟准观测的实施要点。列举了拟准检定法在图相关情况下的粗差检测,形变分析中的异常探测以及GPS相位观测的周跳检测和修复等方面的应用例子。In this paper,the idea,principle and properties of Quasi-Accurate Detection(QUAD)method are introduced in detail.The key of QUAD is how to correctly select the Quasi-Accurate Ob-servations (QAOs).The main points of the implement in the preliminary and the fine selection of the QAOs are discussed.Some application examples on QUAD are illustrated,which include the gross er-rors detection in the case of the figure correlation,the abnormal detection in the deformation analysis,and the circle slip detections and repairs of GPS phase observations
