• 面めん心しん立りっ方ぽう格こう子し

  Face-centered cubic lattice; atoms are at each corner and the center of each face, unlike the body-centered cubic lattice which has an atom at the cube center.

• 単たん純じゅん立りっ方ぽう格こう子し

  Simple cubic lattice; atoms only at the corners, without the central atom found in the body-centered cubic lattice.

Compound of 体心 (body center) + 立方 (cube) + 格子 (lattice), describing the lattice type with an atom at the center of the cube.
