The fluxes are basically some complex distributions of the motion deployed by a set of objects, at first, spatial distributions (Euler-type, at a given t moment, an overall state of the flux at that moment), then, temporal distributions of the spatial ones. Briefly, we may say that these are spatial-temporal distributions of the above-mentioned motions. Just like in case of any other distribution, there will be at least one element of it, that is an uniform distribution. In case of the realizable fluxes, the spatial distribution element is represented by the flux quantum or by the elementary flux.
Because the intensity of a flux is determined against a steady reference surface, the two levels of the realizable fluxes quantification - the flux quantum and the elementary flux - refer both to the element type of this surface, and to its quantity (attribute stockpile) conveyed by the flux element.
Since they are specific distributed processes, the fluxes are spatial distributions of SEP, namely, vectorial distributions (vector fields).
The elements of these vector fields are a special class of vectors - the carrier vectors - which represent a transport SEP of an elementary quantity from the amount meant for conveyance.
Among the most important attributes of the fluxes, there are few worth mentioning: the closure degree (null for the totally open fluxes), the effective section (invariant for the isotom fluxes), and the coherency degree (which is null in case of the totally stochastic fluxes).
From the point of view of Euler distribution type which is specific to a certain flux, two major flux classes (as virtual models) may be considered: the totally coherent fluxes (with an even Euler distribution) and totally stochastic fluxes (with a totally chaotic Euler distribution).
Besides the very general classifications of the fluxes according to the virtual models, which have been already presented, the real fluxes can also be differentiated (distinguished) according to the type of the conveyed attribute, and in case of the same type of conveyed attribute, another fluxes differentiation may be operated, based on the carrier object type which conveys that particular attribute. For instance, in case of abiotic MS, an essential amount which is conveyed by all the fluxes is the energy. We shall see in chapter 7 that the energy attribute is transmissible and it has as many carrier types, as many forms of matter existence are (photons, electromagnetic waves, pressure waves, EP, NC, missiles, asteroids, galaxies and many more). The same situation with the information fluxes, where its carriers (ISS) are also very diverse.
Finally, we must underline that the motion of an object means the motion of all its model attributes; if there is a complex object, this motion is transmitted (distributed) to all its components, therefore, the properties contained at deeper analytical levels shall be also moved, even if these properties are not transmissible. According to the objectual philosophy, a motion of an amount cannot be taken into account without the existence of some objects which are the support of that amount. For example, in case of the energy fluxes which were above mentioned, some objects which are the support of that property must exist at any analytical level of the material systems organization.
