图5 μ相[112¯0]方向的原子级HAADF-STEM像及沿着黄色线条的强度分布，及μ相[112¯0]方向的原子模型(洋红色箭头在图上标出了μ相晶格常数c，红色箭头指出了中心原子和五角反棱柱原子的位置，右下角插图为μ相内五角反棱柱原子和中心原子沿着[112¯0]方向的堆垛)

Fig.5 Atomic-resolution HAADF-STEM image of μ phase viewed along [112¯0] direction (The intensity profile of the atoms is shown below the panel) (a) and atomic model of μ phase viewed along [112¯0] direction (the magenta arrow shows the lattice constant c of μ phase; the red arrows indicate the positions of the central and pentagonal antiprism atoms; the figure at the lower right panel shows the stacking of pentagonal antiprism atoms and central atoms along [112¯0] direction of μ phase; R—rectangle structural subunit, P—parallelogram structural subunit) (b)
