Body-centered cubic (BCC) is a crystal structure that consists of a cube-shaped unit cell with atoms located at the corners and in the center of the cube. In this structure, each atom is surrounded by eight nearest neighbors located at the corners of the cube. Advertisement Corrosionpedia E...
結晶固體的某些性質取決於其晶體結構(crystal structure),亦即依原子、離子或分子在空間中的排列情形而定。 圖3.1 3.3 單位晶胞 描述晶體結構時,通常會將整個結構細分為許多具有重覆性的小單元,稱為單位晶胞(unit cell)。對大部分晶體結構而言,單位晶胞是具有三組平行面的平行六面體或稜柱體。 單位晶胞用來表示晶體...
