Обосновывается возможность применения на других территориях метода, разработанного для расчета содержания сульфатов, никеля и меди в снежном покрове вокруг комбината "Печенганикель". Рассматриваются связи выпадений вещества из атмосферы за теплый период и в целом за год с их поступлением на подстилающую поверхность за зиму, определяются границы импактных зон, анализируется влияние рельефа на количественные показатели атмосферных выпадений.

Рассмотрен вопрос соразмерности института финансового контроля финансовым потокам. Автор показывает, что матричное упорядочивание финансовых потоков с использованием системно-функционального подхода позволяет сбалансировать функции представительного и исполнительного контроля и основные характеристики потоков (объемы, структуру, направленность).

The supersonic flow around the plate with front flap with formation of Prandtl – Meyer waves and attached stationary shocks is analyzed. Limitative angles of attack of plate and flap are found. The problem of maximization of the lift force of plate owing to the front flap is solved 

Настоящая обзорная статья посвящена истории и современному состоянию проблемы 

Дискуссии вокруг "инварианта" продолжаются по сей день. Современному состоянию вопроса посвящена обзорная статья Н.И.Акатнова, опубликованная в этом номере.

We research particle dynamics in the secondary self-oscillations flow forking from two-dimensional spatially-periodic stream when one of the periods goes to infinity in 2 cases: 1) the main stream is parallel and 2) non-parallel. In the first case the particle trajectories are level curves of stream function. In the second case in self-oscillations we observe chaotic behavior of the particle known as the Lagrangian turbulence 

The article was devoted to investigation on the behaviour of solid particles in the transonic 2D-flow through a stationary cascade of airfoils. The mass load of particles is assumed to be very low, so that the inverse effect of the dispersed phase on the carrying gas flow, as well as the interaction between particles are negligible. In this case the simulation of two-phase flow reduces to the consequent solving of two problems: (i) computation of the gas-phase flow field and (ii) calculation of particles' trajectories in it. The present results are useful for prediction of those areas of the airfoils that may be subjected to erosion damage 

The calculation model is designed and the characteristics of heat and mass transfer is numerically studied in laminar and turbulent stabilized gas/steam and droplets flow in a pipe. The mod takes into account the droplets evaporation, vapor diffusion and flow acceleration. Simulation of the heat- and mass transfer is compared with experimental and numerical data. In the whole, vaporization of the droplets leads to essential augmentation of heat transfer in comparison with a single-phase vapor flow 

The transversal flow of a plate in the supersonic flow of rarefied gas is considered. The flow is researched on the basis of a numerical solution of a kinetic equation by a method of finite differences.s.The flow about of a heat-insulated plate up to a Mach number 21.90 and the flow about a cold plate up to a Mach number 10.95 is investigated. The area of rarefaction behind a plate is founded. The drag coefficient of a heat-insulated plate is calculated 

The article systematizes some particularities of the processes of following conversion of information quantum stream. The field of such processes effective use is determined. The organization structure advantages of the devices operating with the considered processes are studied, their reliability and fault-tolerant properties are examined. The main units, which perform multiplying and dividing operations with information quantum streams are discussed. On the base of the unit original technical decisions are proposed that will develop the class of multiplying and dividing converters by means of feedback of various types. The base is shown of effective realization of the considered unit with the use of programmable logic devices
