“crystal”的概念、定义、翻译、参考文献-科学参考

crystal

Physics

A solid with a regular polyhedral shape. All crystals of the same substance grow so that they have the same angles between their faces. However, they may not have the same external appearance because different faces can grow at different rates, depending on the conditions. The external form of the crystal is referred to as the crystal habit. The atoms, ions, or molecules forming the crystal have a regular arrangement and this is the crystal structure.

Chemical Engineering

A pure and homogenous solid form of matter in which the atoms, molecules, or ions are arranged in a regular and orderly three-dimensional array or lattice. A crystal structure is formed by the regular arrangement of atoms, molecules, or ions in which they have the same angle between their faces. However, depending on the conditions, different faces can grow at different rates, leading to slightly irregular-appearing shapes. Compare amorphous.

Geology and Earth Sciences

A homogeneous, ordered solid, having naturally formed plane faces and a limited chemical composition. Crystals have definite geometric forms that reflect the arrangement in lattices of the atoms of which they are composed. See crystal class; crystal symmetry.
