The criterion for local equilibrium

Therefore, 2 2 2( ) ( ( )) et tθ θ δθ θ= + , where δθ2(θ(t)) is the correction

to the value of the equilibrium paired DF due to the influence of the flow of molecules changing the density as a function of time θ(t). Or, the main difference between the notions of a stationary (quasi-equilibrium) and equilibrium is the appearance of δθ(2)(θ(t)) a correction depending on the properties of the flow, with their general property – the independence of the pair DF on time dθ2/dt = 0.
