A novel approach to diffraction analysis of decorated quasicrystals is discussed. An average unit cell has been constructed for a decorated Fibonacci chain and used for analysis of its diffraction pattern. After some transformation of the scattering vectors, all the diffraction peaks are described by a single envelope function which is characteristic of a given decoration. It has been shown that by knowing several diffraction intensities, in a limited range of the scattering vector, it is possible to reconstruct the envelope function successfully and distinguish between different decorated structures.
讨论了一种用于修饰准晶体衍射分析的新方法。已为修饰的斐波那契链构建了一个平均晶胞，并用于分析其衍射图案。在对散射矢量进行一些变换后，所有衍射峰都由一个单一的包络函数描述，该函数是给定修饰的特征。结果表明，通过知道在散射矢量的有限范围内的几个衍射强度，就可以成功地重建包络函数并区分不同的修饰结构。
