The spectral characteristics of the new functional materials based on a single device spatial field
Abstract: This article is devoted to the theory of a single spatial field, the objective existence of which is established on the basis of the interaction of electrical, magnetic and gravitational forces has been developed multifunction installation of a single spatial field.
Keywords: devices, magnetic fields, electric fields, gravitational fields.
The aim of this work is the analysis of the experimental data on the basis of a single device of the spatial field (SDSF), and identifying opportunities for its use for new functional materials [1, 75].
Dispersion of solids (dry milling) into a special branch of science of technology. It deals with the mechanical strength required for the destruction of the structure and the structure of solids, as well as research and design of crushers, mills and similar facilities for rational grinding [2, 212].
Results grinding evaluate changes grading curve, an increase in the specific surface of the material.
The quality of these units is evaluated by comparing required to create new surface energy and operating costs. Resulting in the production of artificial stone, the quality of the structure of materials require optimal fineness.
Dispersion solids — of grinding to small particles is carried out
to enhance the rate of heterogeneous processes. In the process of dispersing discernible two main stages: the destruction of the particles by an external force and aggregation of particles such as spontaneous or caused by external compressive and tensile forces [3, 143].
Along with dispersing and aggregation during milling changes the crystal structure and energy state of the surface layers of particles. Their study presents grinding.
Due to the high cost and energy intensive fine grinding using the existing facilities have been designed with the device SDSF allowing dispersion material dispersion 500 microns to 1,5 microns.
The device is a single spatial field, based on the four fundamental interactions, and thus on the interactions of four types of fields: gravitational, electromagnetic, magnetostatic, electric (Fig.1).
External fields create compressive or tensile forces that result in fracture and particulate materials [4, 11].

Calculation of optical-geometrical characteristics of parabolic-cylindrical mirror concentrating systems
Abstract: The paper identifies the main optical and geometric characteristics of parabolic-cylindrical mirror concentrating systems (MCSs) of energy purposes, taking into account the characteristics of attainable manufacturing modern MCS.
Keywords: mirror concentrating systems, parabolic-cylindrical, concentrator, focus, optical power parameters.
It is known that the solar concentrators are constructed on the basis of composite reflective elements — facets. The geometry of the concentrator to the spot of is a parabolic and for linear focus — parabolic -cylindrical. The geometry of the facets may differ from the estimated concentrator's geometry. Introduction to the geometric method of concentrator inaccuracies reduces the problem of calculating faceted concentrator to the calculation of solid MCS. In addition to the energy-power devices MCS provides the highest efficiency of solar energy conversion. Therefore, the calculation of optical-geometrical parameters parabolic-cylindrical concentrators, as well as to determine the optimal size of radial surface of the receiver is an actual problem [1-3].
The degree of concentration optimal MCS values for converting solar energy into other forms of energy used in practical computed as follows.
To calculate the energy distribution in the focal zone parabolic-cylindrical MCS trajectory of the incident and reflected rays of the Sun is seen as a set of countless individual elementary beams based on the vertices of the point system reflecting surface. These sunlight beams having an elliptical cone shape, called elementary mappings. The rays, which are on the outer surface of the cone, called marginal rays and the angle between the two — the angular size of the unit display. Thus, the elementary display size depends on the size of the solar disk, the actual distance to the sun, that is, the visible angular size (Earth 2y0= 32 'arc min.) As well as the reflectivity, manufacturing precision reflector geometry and in aggregate form Sun's image. Real image dimensions are different from Rc and determined based on Figure 1.
