The structure of measuring stands of ultra-high-frequency installation of drying and baking of bricks is considered. The creation of a practical microwave installation is determined by the creation of measuring stands at a low power level, by working on electrodynamic models and by creating appropriate laboratory installations of a high power level. The measuring stand of the described structure allows to check the matching characteristics of all waveguide elements of the feeder chain, adjustment of waveguide tees, and the development and tuning of the energy input units to the microwave chamber of the experimental setup. In the laboratory installation it is proposed to use the industrial generator KIE-5, operating at a frequency of 2.45 GHz with a maximum output power of 5 kW and a waveguide ferrite circulator. The maximum power of such an installation differs only 10 times from the power of the experimental setup. This makes it possible to reliably estimate the electrical strength and heat release of the experimental unit assemblies from the results of laboratory studies.

In the article the scheme of the measuring stand of the device model for determining the part of the energy distributed from the generator, the scheme of the measuring stand of the model for measuring the standing water coefficient (VSWR) and the measurement of the transient resistance are presented. The best results are obtained by a partition consisting of two metal plates overlapping the path both above and below the clay layer. So, with a clay humidity of 4%, the total attenuation was 14.4 dB (-6.1 dB without a partition), and at a humidity of 16% -35 dB (-18.4 dB without a partition). There is an increase in attenuation of approximately two times compared to the case without a partition for both dry and wet clay, but the amount of attenuation is insufficient. To increase the attenuation in model 2, two consecutive resonators were created. But the attenuation in this case increased insignificantly in comparison with one resonator. It is obvious that two resonators are upset because of mutual influence on each other. Therefore, it is proposed in a real installation between these two resonators to place a section of a waveguide of nonresonant length with an absorber that will eliminate the coupling between the resonators.

The problem of identification of defects in the construction in the form of a wall element is considered. Numerical simulation of the structure is carried out in the Ansys finite element complex. The investigated model of a wall structure has a defect in the form of a through crack, of a certain length. The edges of the cracks do not interact with each other. The excitation of the structure under pulsed loading is considered. Wave field displacements at control points are analyzed. Identified signs of identification of crack-like defect.

The processes of extraction and processing of oil and oil products are accompanied by negative consequences at the level of the environment in the form of accidents. They act both on the water area and on land. This article is devoted to the liquidation of emergency oil and oil products spills with the help of natural sorbents. For the analysis, three readily available materials were taken in the national economy of the Russian Federation: wool, wheat straw and sawdust. The main indicative value for the sorbent is its oil capacity (sorption capacity) the amount of absorbed oil, which depends on the degree of specific surface of the material. The higher the specific surface area, the higher the sorption capacity. To determine the oil capacity, each of the materials was placed on a flat surface and artificially contaminated with oil for one hour. During the experiment, the absorbent capacity of the sorbents was determined, which for each proved to be different. Based on the data, graphs are constructed that clearly show the applicability of a material.

To produce controlled radio frequency and microwave devices such as phased antenna arrays, delay lines, an affordable and inexpensive way of manufacturing varactors in large quantities should be found. One of the promising ways to produce such varactors is based on the use of a BST-paste with a low firing temperature, which allows it to be integrated into a substrate of low-temperature co-fired ceramics (LTCC).

A new class of materials is proposed that change their dielectric permittivity as a function of the magnetic field strength. Such materials are two-phase composites of composition La0.7Sr0.3MnO3 / I, where I is the isolating phase, Li4P2O7 or GeO2. The ratio of components is close to the percolation threshold: from 10% to 20% by weight. Dielectric properties have been studied in the frequency range of the measuring field from 1 kHz to 1 MHz in magnetic fields from 0 to 15 kOe. Samples have an inductive impedance, their permittivity is negative. In a magnetic field, the permittivity increases in absolute value and at room temperature the values of the magnetodielectric coefficient reach 28%.

New highly-porous film materials were created based on NA-sodium carboxymethyl cellulose, modifyed by particles of AlOOH. Forming of covers happen as a result of relatively not high temperatures (for about 55 degrees of centigrades). A regression model was suggested which described interrelation between sizes of forming porouses in the film cover with its composition. The ability was shown to manage physical specification of the cover which named surface porosity by changing containing of AlOOH in the composition. It was shown up that porouses were formed sizes between 300 mircometers and 2500 mircometers in proccess of curing of the cover while containing of boehmite in the composition. It was discovered that the general surface porosity was 65%, and the depth of cover was 600 mircometers. The ability was shown to create covers with sliding properties as exemplified in closing of pores by solid lubrication MoS2. It was discovered that it was observable down drag by 30-50% in response to application of covers on steel faces adding down of frictional force.

When developing large information-measuring and control systems, special attention must be paid to the interaction of various blocks of the system with each other. For example, the structure of a software-hardware measuring channel consists of four consecutively connected elements: primary converter; analog-to-digital converter; software dynamic converter; digital to analog converter. To find the parameters of the measurement channel error, mathematical models were constructed for each of the blocks. Simulation modeling of the measuring channel was carried out. As the input signal, the first-order aperiodic link model is taken. To generate the interference signal, a random number generator with a noise level of 0.5 is used. The error for the measuring channel is found. The suggested mathematical model allows to find the tuning coefficients of the software of the measuring channel, which ensure the minimum information loss in the software-hardware measuring channel. The resulting model can be used in automatic control systems for the current identification of regulator settings.
