Average particle number

Consider an ideal gas system consisting of a large number of particles. The nature of the macroscopic system could not be described in detail. It could only be described in terms of averages, i.e. only the mean values of the thermodynamic quantities characteristic of the medium of the macro system. The average values of the thermodynamic quantities characterizing the macroscopic state of the system such as state equation, free energy, the internal energy, etc. could be calculated by Boltzman distribution function.

In this work we consider a version of generalized q-deformed fermionic oscillators and some their applications. The corresponding coherent states are constructed. The statistical distribution of generalized q-deformed fermionic oscillators system, expressions for quadrature variances and the average particle number in the coherent states are calculated.

Soil acidification is caused by a number of factors including acidic precipitation and the deposition from the atmosphere of acidifying gases or particles, such as sulphur dioxide, ammonia and nitric acid. The most important causes of soil acidification on agricultural land, however, are the application of ammonium‐based fertilizers and urea, elemental S fertilizer and the growth of legumes. Soil samples were collected over a period of 2017-2018 from the entire block, to study physico-chemical parameters of three seasons.

In many-particle case, the blocking effect results in decreasing correlation factor F and average time τjump between two consecutive jumps. With increasing the number of particles, the diffusion coefficient DM decreases for site-energy and transition-energy disordered lattices due to the F-effect affects stronger than τ -effect. Furthermore, the blocking effect almost is temperature independent for both lattices.
