THE RELATIONSHIP BETWEEN EQUATIONS OF STATE FOR SMALL FLUCTUATION-DISPERSE SYSTEMS AND EFFECT OF GRAVITY IN MACRO-SYSTEMS UNDER THE CRITICAL CONDITION
Journal Title: Физика аэродисперсных систем - Year 2016, Vol 0, Issue 53
Abstract
The fluctuation-dispersed structure of small limited systems in critical condition is proposed on the basis of macro-systems phase transitions fluctuation theory. A distinctive feature of this structure is the equality of the number of order parameter fluctuations Nf(s) in the surface layer s=4πl2 with the thiсkness l and the number of order parameter fluctuations Nf(v) in volume v=4/3⋅π(l−2Rc)3. Based on this equation the linear size of a small spherical system have been evaluated, the relationship between the thermodynamic parameters has been determined – the temperature and the chemical potential with the linear size of the system which are similar to relations of M. Fisher t~1 −1/ν , _μ~l −1/ξ . Based on the quality similarities of the non-monotonic temperature dependences of various properties of macroinhomogeneous systems in the Earth gravity field and the non-monotonic temperature dependences of small confined systems properties under critical condition the equation of state has been proposed for small confined systems. This equation has been tested on the basis of experimental data from various properties of small confined systems.
