The analyzes of methods and composition of solder protection from oxidation has been carried out. A more perfect composition for the restoring and protection of the melt of low-temperature solder from oxidation on the basis of fluxing components: glycerin; urea; nano-dispersed carbon and filler (silicon dioxide powder) has been developed.The advantage of the developed composition (material) is an increase in operating time (from 2-3 to 300 hours). Unlike the protective fluids based on glycerol with sodium hydroxide salts, or hardening oils, the operation temperature range increases to 447 K - 723 K, the cleaning and removal of the remains of the protective composition improves. High dispersion of SiO2 (5-15 microns) and highly developed surface (5-150 m2 /g) of technical carbon lead to increase the strength and reduced the porosity of the protective layer, which prevents the evaporation of heavy (toxic) metals in the solder composition.The developed material is tested in the technology of assembly and installation of radio electronic products by soldering method and can be used for low-temperature soldering and tinning conductors by the low-melting solders, as well as electric outlets, radio elements and units of electronic equipment (EE).
对焊料防氧化的方法和组成进行了分析。在助焊剂成分的基础上，用于恢复和保护低温焊料熔体免受氧化的更完美的组合物:甘油;尿素;纳米分散碳及其填料(二氧化硅粉)得到了发展。开发的组合物(材料)的优点是操作时间增加(从2-3小时到300小时)。与基于氢氧化钠盐的甘油或硬化油的保护液不同，操作温度范围增加到447 K - 723 K，改善了保护成分残留物的清洁和去除。高度分散的SiO2(5-15微米)和高度发达的表面(5- 150m2 /g)技术碳导致强度增加，减少了保护层的孔隙率，从而防止了焊料成分中重金属(有毒)的蒸发。所研制的材料在无线电电子产品的焊接装配和安装工艺中进行了试验，可用于低温焊料的低温焊接和镀锡导体，也可用于电源插座、无线电元件和电子设备(EE)的单元。

We report on the development and research of a new class of crystalline nanocomposites with tailored anisotropy for micro- and nanoelectronics, targeting applications in telecommunication networks working in optical and subterahertz wave ranges. Different induced optical effects in mentioned materials are analyzed by extreme surfaces method that allows to determine the global maxima of a specific interaction. The results are obtained for the family of novel nanocomposite materials based on the host nanoporous matrices from silica (SiO2) and anodized aluminium oxide (AAO) filled with nanostructured KDP, ADP, TGS, Ba(NO3)2 and KB-5 crystals. Changes due to various pore diameters, inter-pore spacing and morphology are analyzed.

A technique for calculating the scattering characteristics of a symmetric two-layer discontinuity in a microstrip transmission line is proposed. The discontinuity consists of a capacitive section of a microstrip line and a comb-shaped slot resonator in its ground plane. The technique is based on the transverse resonance method. Electromagnetic field distribution in the comb-slot resonator is described in terms of basis functions of TE-waves of a complex cross-section waveguide. It is shown that proposed structure enables a design of passive devices (filters) with a complex scattering characteristic. The latter covers both bandwidths and wide stop bands with at least three frequencies of the resonant interaction with the microstrip transmission line.

Service-oriented information systems have a complex configuration of interacting components, accounting and analysis of the characteristics of which within one model is very complex and sometimes impractical. Hence, in the given article, two models of the web server complementing each other are proposed for modeling such systems. The models are built on the basis of the Markov chains apparatus, the theory of mass service and colored Petri nets.

The work considers group codes and investigates their structural properties from the viewpoint of decomposing them into non-overlapping cyclical orbits. A method of forming big ensembles of discrete signals with a multi-level correlation function is suggested. The formation of discrete signals is based on cuts of group code non-zero cyclical orbits. The work shows that the suggested method generalizes some discrete signals known before (suborthogonal sequences and Gold codes) and generally allows to synthesize binary sequences with a multi-level correlation function.
