Trigonal hexagonal 違い
WebThe hexagonal crystal family consists of two crystal systems: trigonal and hexagonal.A crystal system is a set of point groups in which the point groups themselves and their corresponding space groups are assigned to a lattice system (see table in Crystal system).. The trigonal crystal system consists of the 5 point groups that have a single three-fold … WebThe trigonal system is a limiting case of the simple monoclinic Bravais lattice, with β = 120∘. It can also be obtained from the base-centered orthorhombic Bravais lattice with b = 3a. The conventional unit cell is described by the vectors A1 A2 A3 = = = 2a x^ − 23 ay^ 2a x^ + 23 ay^ cz^. There are two Bravais lattices in the trigonal system.
