The influence of the substitution disorder and the period disorder on electronic structures of one-dimensional, nearly periodic systems is studied in terms of numerical method. The results show that the Cantor set structure of electronic spectra in the almost periodic systems is destroyed in both the disordered cases, but Ihe former may -create new impurity levels in the forbidden band, and the latter mainly broadens the original energy bands.
