We have summed up a rule that the hexagonal approximants can be classified as three by the strong diffraction spots in their [001] EDPs and the direction of the icosahedra chains in their (001) layers is the structure nature of this phenomenon.

• 总结了六方准晶近似相的一般规律:六方准晶近似相可以根据其[001]带轴上强衍射点的位置分为三种类型,并指出[001]带轴上强衍射点列所在的位置是由(001)层块中二十面体链的方向决定的。
