ABSTRACT
The microscopic specification of the N body system includes: a) specifying the thermodynamic parameters of the system that determine its macroscopic state, or the specification of the external conditions into which the system under consideration is placed; b) the actual task of the system based on the atomistic approach: we know all the microscopic characteristics of the system, that is, the masses and structure of its constituent molecules, the charges and spins of the particles, the potentials of their interaction with external fields and with each other, etc.
