摘要
A theoretical investigation for the role of nonlinear couplings between elements of damage structure of irradiated crystal in its self-organization and influence of fluctuations of defect generation rate on this process is developed. It is shown that nonlinear couplings determine kind and parameters of the arising spatial structure or terminal behavior. Parameters of the arising structures and conditions of its development are obtained. It is determined the fluctuations of irradiation conditions most strongly apparent in dynamic behavior of system. As a result new unstable regions and new dynamic behavior that do not have determinate analog appear. The cause of it is strong interaction between fluctuations that is accompanied by their essential increase.
