fractional coordinates
- 分数坐标：在晶体学中，分数坐标系统（晶体坐标系统）是一种坐标系统，其中用于描述空间的基矢是晶体（周期性）图案的晶格矢量。选择一个原点和一组基矢定义了一个单位胞，即由晶格基矢定义的平行六面体（2D情况下是平行四边形，3D情况下是平行六面体）。

Fractional coordinates
- abstract: In crystallography, a fractional coordinate system is a coordinate system in which the edges of the unit cell are used as the basic vectors to describe the positions of atomic nuclei. The unit cell is a parallelepiped defined by the lengths of its edges a, b, c and angles between them α, β, γ as shown in the figure below.
