摘　　要：揭示现代产品几何技术规范(geometricalproductspecificationandverification,GPS)中规范过程和检验/认证过程的物象对应关系,以及其表面模型存在着对偶性、操作技术存在着共性的内在规律性;并以几何误差的检验/认证过程为例,阐述利用操作及算子技术实现GPS计量过程数字化的可能性及应用规律;进一步明确基于对偶性的表面模型、操作及操作算子技术,对于实现GPS设计与计量的统一性、与CAx的集成性和数字化功能是至关重要的。Indicate object-mirror corresponding relation between the specification stage and verification stage of geometrical product speeification and verification（GPS）, and the inherent regularity between the duality of their surface models and commonness of their operation teehnology. By taking the verification process of the geometrical error for example, it expounds the possibility and applieation regularity of realizing GPS measure process digitization through the use of operation and operator technolodgy. Moreover, illuminate that the surface model, operation and operator technology based on duality are critical in realizing the unity between GPS designs and GPS verification, integrating with CAx and the digitized function.
