The electronic energy structure of the row of similar compounds: diamond (C), BN, and BeCN2 has been investigated. It was found for BeCN2 that the top of the valence band is formed by p-states of N, whereas the bottom of the conduction band - by s-states of Be and C. The width of the energy forbidden band Eg in BeCN2 - was estimated. The comparison of the calculated partial and total electron densities of states of diamond and BN with x-ray K-spectra of emission and absorption and with x-ray electron spectra was carried out. The corresponding partial electron states of diamond and BN were also compared with corresponding densities of states of BeCN2.

In paper it is offered to use the linear models of drives of combines to build the standard dynamic characteristic representing a response of system of a drive on a unit impulse excitation. Such performance is termed by a pulsing transition function of a drive of a combine p.t.f. The analytical model p.t.f. is gained. Also the path of implementation of the strategy of optimum projection of parametres of transmissions of combines by statistical measure is displayed.

The interrelation between forces acting in damp grain materials is defined. Also the rate of each force influence on grain condition in the bunker is calculated and the grain and grain-bunker coupling forces are determined experimentally.

A general approach of the constructing of a functioning stochastic multimeasured analytic model, describing dry materials system separation on different combinations of special technological operations forming cleaning aggregate structure is given here.

Experimental and theoretical studies of the use of motor fuel quality EURO standard diesel locomotive. Explicit technical, environmental and economic effects of the use of fuels and EURO4 EKTO in shunting locomotive compared with diesel fuel according to GOST 305-82. As a result, the tests demonstrated improvement in traction, launch and fuel-economic characteristics of the diesel engine. Experimentally confirmed by the reduction in emissions of soot, carbon monoxide, nitrogen and greenhouse gases.

In article results of researches of the basic technological parameters of methods of superficial plastic deformation are presented by the flexible granulated environment. Depth of introduction of a particle of environment, an average arithmetic deviation of a profile of the established roughness, depth of the strengthened layer and hardening degree is defined, dependence of a roughness on time for various kinds of processing by a method of superficial plastic deformation by the flexible granulated environment is resulted.

The problem about funding of structure of isolation with greatest stability is considered. In the article, there are results of isolation characteristics of crucible furnaces for smelting of cast iron. Modeling of mix preparing for isolation is carried out and its optimal structure is defined. Recommendations of selection and preparing of structure of isolation with the greatest resistance are given.

There are result of analyze for improvement Diesel engine quality roving to limited thermal drainage in the article. Peculiarities of degree influence thermal isolation for main engine parameters had been considered there. Possibility of waste gases energy utilization was discussed in it.

Gallium polyphosphate was synthesized using the method of solid-phase reaction between Ga(NO3)3 and NH4H2PO4. Some properties of gallium polyphosphate and compound on its basis, such as index of refraction, density, conduct- ivity were studied. New composition of semiconductor film is developed, and the properties semiconductor film at the base of gallium polyphosphate.

In present clause the decision of a linear problem of calculation of an electromagnetic field in system a conductor on which the sine wave current covered with a ferromagnetic conducting pipe proceeds is resulted. The resulted analytical researches are confirmed with experimental data which results allow with a sufficient degree of accuracy to define the characteristic of ferromagnetic conducting environments.

On the data on quantity of the including and left passengers at each stop of all route the method of definition of the passenger correspondence by a settlement way and on the basis of the received researches the software is offered.

Approach is offered In article to minimization boolean function, founded on use automaton to adaptation. As bases is used known method to minimization boolean function, founded on partition implicant units made disjunctive normal form boolean function on two ensembles and join nearby implicant. The Proposed automaton to adaptation, in the event of hit in local optimum allows to realize return to previous decision. Given characteristic allows effectively to come out of local optimum.

 

We considered movement of electroconducting greasing in a backlash of the radial bearing in the presence of electromagnetic field with the account of its dependence of viscosity and electroconductivity on temperature. We estimated influence of the parametres characterising magnetic induction and intensity of electric field on the basic performance data.
