本文首先提出了面条模型的概念，进而指出基于面条模型的图形处理系统如果不具备动态生成空间关系的能力，就会退化为简单的地理数据库，提出了面条模型中动态推断空间关系的基于Voronoi图的四邻近数学模型（4-adj模型），给出了唯一、完备的推断规则，并指出其优点和不足。

The concept of spattio model is proposed firstly in this paper. Furthermore, it points out that the graphic system based on spattio model will degenerate into a simple geodatabase if it doesn't have the ability to dynamically generate spatial relations. At last, the paper proposes the new method called four-adjacent mathematical model (4-adj model) based on Voronoi diagram to dynamically infer the spatial relations in spattio model, and gives the only complete inference rules, together with the advantage and disadvantage.
