摘要：
Factor properties and their structures are important themes in combinatorics on words. Let D be the infinite one-sided sequence over the alphabet {a, b} generated by the period-doubling substitution σ(a) = ab and σ(b) = aa. In this paper, we determine the derived sequence D(D) for any factor ω■D, and study some factor spectra using the structures of derived sequences. We also prove the reflexivity property of derived sequences.
