Аннотация: The concept of polymer nano-heteromorphic structure and relaxation of the glass-forming substance considers the glassforming systems comprised of one or more components. The concept of polymer-polymorphoid structure and relaxation of one-component glass-forming substances (or an individual chemical substance (ICS), element or chemical compound) is the unique focus of this concept. One-component glass and glassforming liquid was constructed from copolymers in varying degrees polymorphoids or crystal structure nano-fragments of different polymorphic modifications (PMs), which do not have translational symmetry (long-range order), but having short and intermediate-range (mediumrange) orders. Polymorphoids may be missing (non-polymorphoids glass) in the glass containing more than one component. There is a genetic relationship between the glass and its crystal and liquid analogues, which has been manifested in the response to the external influences. The main feature of such glass reaction containing various PM polymorphoids was their inter-conversion, which is analogous to the inter-conversion of polymorphic modifications in the crystalline substance. This feature makes it possible to quantify the structure nano-diagnostics in glasses containing PM polymorphoids and determine their concentration ratio (CRP) for example for such compounds as S, Se, GeS2, GeSe2, As2Se3, B2O3, SiO2, GeO2, H2O, BeCl2 etc.
