- Establish the adjacency relation among all pairs of components which share a pair of pseudovertices.
- There are a lot of adjacency relations in the natural heritage.
- The geometric model from CAD system contains a great deal of trimmed parametric surfaces, and the adjacency relation between trimmed surfaces is very complex.
- As adjacent relation is a complex system in real Laws, we should interpret its complex character from different perspectives, and use various regulating methods.
- The concept of the adjacent relation is the generalization and Abstraction of real life,which is processed by legal thinking and more Abstract than real life.
