文摘The existence of diffraction spots possessing icosahedral (Ih) point-group symmetry, discovered by D. Shechtman et al. on electron diffraction patterns of rapidly solidified Al-Mn alloys, has changed the conventional way of dividing solid states into crystalline and noncrystalline. Quasicrystalline, a new state
