The general binary relation-based variable rough set model is proposed on the
bases of rough set models based on tolerance relation,non-symmetrical
similarity relation and limited-tolerance relation,which is the generalization
of rough set models based on various of special binary relations(e.
該文以基於相容關系、非對稱相似關系及限制容差關系的粗糙集模型爲特例,提出了基於一般二元關系的可變粗糙集模型,它是基於各種具體的二元關系
(如相容關系、非對稱相似關系、限制容差關系、量化容差關系等)粗糙集模型的推廣,也是不完備信息系統變精度粗糙集模型的一般情形。

6) primitive relationship
基元關系

The paper also presents the technologies of primitive relationship conversion
and primitive shape-location adjustment to translate tangent relationship into
scan and connected relations,to translate surface solid interceptive
relationship into intersected relationship,and to adjust the shapes and
locations for obtaining correct reconstruction results.
