Разработка систем управления станков с ЧПУ при помощи программной среды MexBIOS Development Studio

The application of the Lorentzian plasma theory for the calculation of the properties of multicomponent electric arc plasma is considered. It is shown that this model gives satisfactory results in the temperature range, which is corresponding to the weakly ionized arc plasma and arc plasma with dominant first ionization. The calculations are provided for the arc plasmas of noble gases and their mixtures between them and also that with metals. It is also pointed that the discrepancy between the electron temperature and gas temperature can be significant even at relatively weak electric fields, that fact must be taken into account under the simulation of arc discharges

Influence of Inhomogeneity on Transformation and Radiation Processes in Plasma with Upper Hybrid Pump

On the basis of the kinetic theory of fluctuations, the processes of the longitudinal Langmuir wave transformation into a transverse electromagnetic wave in the turbulent inhomogeneous plasma have been studied. The plasma turbulence is assumed to arise owing to the parametric decay of the upper hybrid pump wave into a daughter wave and electron-drift oscillations. The transformation coefficient under the parametric instability saturation conditions is determined. The intensity of the electromagnetic radiation emission from the plasma is calculated, and its dependence on the plasma and pump wave parameters is found.</jats:p

Investigation of metal evaporation and film deposition at middle vacuum by using a glow discharge electron gun

Glow discharge electron guns are widely used for realising different technological operations in the soft vacuum [1-4]. Its may be successfully applied for reactive evaporation of thing film of oxides and nitrides, which are used for covering of mechanical instrument and for obtaining of dielectric films in microelectronics [3,5]. In the present work the mathematical model of steam flow distribution and it condensation in the substrate is proposed and realised and its experimental verification provided
