râžmân-e bolur, ~ boluri
Fr.: système cristallin
One of seven possible basic crystal types that is defined by the relations between the axis lengths and angles of its unit cell. Crystal systems can produce an infinite → lattice by successive translations in three-dimensional space so that each lattice point has an identical environment. The seven crystal systems are: → cubic, → orthorhombic, tetragonal, trigonal, hexagonal, monoclinic, and triclinic.
cubic crystal system
râžmân-e boluri-ye kâbi
Fr.: système cristallin cubique
A → crystal system whose three axes have equal lengths and all corners are 90°.
orthorhombic crystal system
râžmân-e boluri-ye ardâlowzik
Fr.: système cristallin orthorhombique
A → crystal system that has three mutually perpendicular axes, each of which is of a different length than the others.
