The common regularity of the defect influence on the modulated structure dynamics has been determined. The stationary defects cause the local changes of the phase of incommensurate structure. The movable defects as a result of their ordering in the modulated structure field induce appearing of several modulation waves in one crystallo-graphic direction. In this case the total modulation is determined through the superposition of the such modulation waves. Product Description popup.authors popup.nrat_date 2020-04-02 Close
