在金属Cu、NaCl晶体中,质点(Cl~-离子、Cu原子)占据着面心立方的各个结点,晶格的几何外形均为立方晶系。论述了晶体结构中的面心立方与立方晶系。
In the metallic Cu and NaCl crystals, the particles (Cl~-ion, Cu atom) occupy each of the face-centered cubic nodes, and the lattice geometry is cubic. The face-centered cubic and cubic crystal systems in the crystal structure are discussed.
