  • Influence of the manganese nitrate surface phenomena characteristics on impregnating tantalum capacitor anode

    The influence of manganese nitrate impregnating solutions concentration and temperature dynamic viscosity, the wetting angle, interface “porous tantalum electrode - solution” free surface energy and the impregnation degree of porous tantalum anode was researched. A quantitative characteristic of manganese nitrate solution application on porous tantalum anode of solid-electrolyte capacitor during the process of impregnation was defined and work of adhesion and cohesion was calculated. Thus increasing of solution concentration above 42% wt brings to sharp growth of surface tension and so work of cohesion is increased but carriers impregnation is fallen. The most effective impregnation is realized at concentration 27% wt. This fact corresponds to best value of tantalum anode capacitor free surface energy. So using received data we are able to estimate optimal conditions of impregnation and wetting process by nitrate magnesium.

  • Model of application of system mimo for suppression of reflections from the surface of earth in the way beamforming

    Suppression of a signal reflected from the underlying surface is being performed for the cause of location of the low-lying objects. Since the spectral characteristics of the signal and noise match, spatial difference is formed by oblique irradiation. Spatial differences are allocated by the radiation pattern. The suppression is performed by forming the zero value in the equivalent radiation pattern. The equivalent radiation pattern is a section of a generalized ambiguity function of the signals. The graphs of equivalent diagrams are shown for several areas of suppression in the view sector. The adaptive system is performing the equivalent radiation pattern zero-value scan of the underlying surface in the view sector. These algorithms are successfully applied to the MIMO system. A feature of the MIMO system is spotted in the task of forming zero values of the equivalent radiation pattern.

  • Influence of specific pressure of pressing and firing temperature on frost resistance of the modified laboratory samples from atyukhtinsky clay raw materials

    Results of researches on joint influence of specific pressure of pressing and firing temperature on physico-mechanical properties of laboratory samples on the basis of atyukhtinsky clay raw materials is shown. For the purpose of increase of frost resistance of the burned samples into structure of masses entered a carbonat containing modifying additive in an amount of 5%.
