Abstract

The graphs of S-curves characterize the general dynamics of change of entropic components depending on the process main parameters. At the same time, their sum is equal to the maximum value of each of them in this interaction. The condition of the system stationary state is the equality or constant of the correlation between its entropy and negentropy (equilibrium dynamics). Such regularities are found in many phenomena and conformational interactions in physical chemistry, nature, engineering and even economy. The examples of their functional contribution are given. The possibility of objective analysis of the coronavirus regional scenario is demonstrated based on the Russian data.
