摘要: 以羊毛纤维和人类头发为原型，以超级分形纤维概念为基础，抽象出了(3)分圆和(9+2)分圆分形集，构造了(3,9+2)分圆和(9+2,3)分圆双重分形集．针对(9+2)拓扑花样，证明了这样的命题：(9+2)拓扑花样精确地存在，但不唯一，其总个数为9，其中有2种同素异构体，即9种拓扑花样中，只有2种是独立(或基本)的．另外证实了(3,9+2)或(9+2，3)分圆分形花样是一个对称性破缺的黄金分形．

Abstract: Based on the concepts of fractal super fibers, the (3, 9+2)-circle and (9+2, 3)-circle binary fractal sets were abstracted from such prototypes as wool fibers and human hairs, with the (3)circle and the (9+2)circle fractal sets as subsets. As far as the (9+2) topological patterns are concerned, the following propositions were proved: The (9+2) topological patterns accurately exist, but they are of no uniqueness. Their total number is 9. Among them there are only 2 allotropes. In another word, among the 9 topological patterns only 2 are independent (or fundamental). Besides, it was demonstrated that the (3, 9+2)-circle and (9+2, 3)-circle fractal sets are golden ones with symmetry breaking.
