STUDY OF PSEUDOSYMMETRY OF ONE-DIMENSIONAL CRYSTAL WITH AN IMPURITY
The model of a one-dimensional crystal with an impurity has been considered. A procedure has been developed to calculate an average degree of pseudosymmetry as a function of a linear scale of the crystal fragments, as well as the degree of pseudosymmetry averaged over the whole scale range as a function of impurity concentration. The most general regularities of pseudosymmetry behaviour of the one-dimensional crystal with the impurity have been revealed.
