采用多重散射的方法研究了十二重准晶中的缺陷模,发现在十二重准晶中存在方向缺陷,且当缺陷组合围绕对称中心旋转时,在保持原有缺陷模的基础上,出现了新的缺陷模. The multi-scattering method was used to study the defect modes in the 12-fold quadruple quasicrystal. It was found that there was a directional defect in the 12-fold quadruple quasicrystal, and when the defect combination rotated around the center of symmetry, on the basis of maintaining the original defect modes A new defect mode.
