Dynamics of Changes in Dimensional Characteristics of Atom-Molecule Interactions in Phase Transitions

摘要

In phase transitions the radii of atomic-molecular interactions change between separate crystal systems under external actions. In aqueous solutions such sphere radius is approximately three times larger than the atomic radius. It is demonstrated that in general case this radius can be assessed via the effective main quantum number, and the system interaction degree can be calculated applying the idea of spatial-energy parameter (P-parameter). Such parameter is a complex characteristic of the most important atomic values responsible for interatomic interactions and having the direct link with the electron density of valence orbitals. The application of such approach to the evaluation of surface diffusion in the system C→Cu is given. At the same time, the number of interacting particles in the surface layer is recorded via their relative number in comparison with their total amount in the interaction area. The identical graphs of carbonization rate and degree of structural interactions on the coefficient of structural interaction a are obtained. Such graphs are similar to the entropic nomogram previously obtained.
