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.

Using the projection and Fourier transform methods,we have derived the diffraction formulas and discussed the rules of diffraction peaks and systematic absences for the one-dimensional Fibonacci-class quasilattices.Moreover,we have calculated and labeled the positions of the diffraction peaks of FC(1) and FC(3).In order to check our diffraction formulas,we extend the formulas to the FC(n) quasiperiodic superlattices.Comparing the present diffraction results of the FC(1) superlattice with the experimental data,we have found that most of them agree with each other but one of the spectra is not consistent.Particularily,we doubt that the peak (4,2) in the experiment should be a stronger peak.
