Explanation

Also known as space lattice. There are a total of 14 types of spatial arrays with infinite identical points arranged periodically in any direction? It is used to express the internal structure of all crystal. It was first established by French crystallographer A. Bravais using mathematical methods and later confirmed through experiments. Its basic characteristics: the space environment of each geometric point (array) is the same, 1 [1] and has the characteristic of translation. Therefore, this kind of lattice is also called translation lattice. The space lattice can be filled with atoms or molecules of specific substances to form a specific crystal lattice of substances. Each space lattice can express many specific crystal structure. All crystal structure can be included in these 14 space lattice without exception.
