摘　　要：本文提出一维k组元的Fibonacci结构,它包含k个无公度的基本长度,是具有两个基本长度的标准Fibonacci结构的自然推广,投影理论被用来处理它的X射线衍射花样及其指标化问题,理论模拟被用于验证投影理论的结果,值得注意的是,对于有限的链长,当k足够大时,它的衍射谱将趋于混沌。A one-dimensional k-component Fibonacci structure, which includes k incommensurate intervals, is the natural extension of the Fibonacci structure with two intervals. The projection method is applied to deal with the pattern and indexing problems of X-ray diffraction. The theoretical simulation is performed to prove the projection method for this extended Fibonacci structures. The diffraction spectrum will lead to chaos for a finite chain provided that k is sufficiently large.
