四方晶系，也叫正方晶系，它具有一个4次对称轴，该轴是晶体的直立对称轴C轴，另外两个水平对称轴和C轴相互垂直相交。轴角α=β=γ=90°，轴单位a=b≠c。

Tetragonal crystal system 四方晶系
In crystallography, the tetragonal crystal system is one of the 7 lattice point groups. Tetragonal crystal lattices result from stretching a cubic lattice along one of its lattice vectors, so that the cube becomes a rectangular prism with a square base (a by a) and height (c, which is different from a).
