利用傅里叶变换方法推导了一维Fibonacci类 (FC(n) )准晶衍射的结构因子方程 ,讨论了该系统的衍射峰和系统消光规则 .在此基础上 ,计算了FC(1)和FC(3)准点阵的衍射谱 .另外 ,把所得方程进行推广使之能用来研究FC(n)准周期超晶格的衍射性质 .通过把FC(1)准周期超晶格衍射相对强度的计算结果与Merlin等人的实验结果进行比较 ,发现大多数衍射谱符合得较好 ,但有一条谱不一致 .理论计算表明Merlin等人标定的谱 (4 ,2 )应该是一个次强峰 .
The structural factor equations of one-dimensional Fibonacci (FC (n)) quasicrystal diffraction are deduced by the Fourier transform method, and the diffraction peaks and extinction rules of the system are discussed. On the basis of this, (3) quasi-lattice. In addition, we generalize the resulting equations to study the diffraction properties of the quasi-periodic superlattices of FC (n). By comparing the quasi-periodic superlattices of FC (1) Compared with the experimental results of Merlin et al, we found that most of the diffraction spectra are in good agreement, but one of the spectra is inconsistent. The theoretical calculation shows that the spectrum (4, 2) calibrated by Merlin et al. Should be a second strong peak.
