The succesive average resistivity criterion for localization has been used to study the Sou-koulis-Economou model of one-dimensional systems with incommensurate potentials. It is found that when wave vector Q = 0.7, all electronic states of the three subbands in the middle are extended and there exist no so-called "local mobility edge".
