One of the most important advantages of the ion lasers based on the ion transitions of metal vapors and noble gases, is the high quality of radiation (high monochromaticity and coherence). However oscillation on each of active media takes place on restricted number of laser transitions. The purpose of this work is receiving a laser radiation at the same time on several quantum transitions in the wide range of wavelengths when using mix of several active mediums. That increases a set of the laser lines radiated by one laser. The characteristics of ion laser transitions (gain, power, noise level) are substantially improved if a hollow cathode transverse-type discharge is used for pumping of the laser transition, and such method of a pumping was used in this work. It was experimentally found the discharge conditions providing various ratio of laser output power on various laser lines for laser on mixture of helium with cadmium and mercury vapors in which the population inversion and laser oscillation are carried out on mercury ion transition with the wavelengths of 615nm (red), and on cadmium ion transitions with the wavelength of 533,7&537,8nm (green) and 441,6nm (blue), and also for laser on mixture of helium with mercury vapors and krypton which lasing on 431,8nm and 469,4nm blue-green krypton ion lines and 615nm red and 794,5 nm IR mercury ion lines. The studied lasers can be useful at information processing, in a metrology, etc.

Numerical solution of the problem of heat transfer in the boundary layers of transparent gas wall, exposed on the opposite side of radiant-convective heating. The energy dissipation due to viscosity is negligible, the wall is thermally thin, and the physical properties of the medium do not depend on temperature. The aim of this work - finding the local heat transfer coefficients (Nusselt number) needed for the analysis of heat exchangers. When solving the problem of nonlinear transfer functions linearizing method is used, based on which numerical scheme for computer calculations was constructed. The intensity of the local heat transfer in the boundary layer is determined by the number Kx = Nux / Nux0, where the value Nusselt numbers refer to the conditions under consideration of the problem of heat exchange (Nux) and constant surface temperature (Nux0). From a physical point of view, non-dimensional parameter Kx is a measure of the intensity of heat transfer in the boundary layer on a nonisothermal surface compared to heat transfer when the wall temperature everywhere the same. The analysis of this research showed that in radiative-convective heating number Kx on the front edge of the plate takes the largest value of Kx ≈ 1,37 corresponding to a constant heat flux on the wall. It is also shown that the relative temperature of the incoming flow has a significant impact on the value of Kx. The effect of this setting is especially evident in the processes when dominated by the effect of radiation and related to the nonlinearity of the transfer processes. The analysis revealed the influence of basic parameters of heat transfer on the development of transport processes in the boundary layer by heating radiation and convection simultaneously.

The method is considered for seaching a single-phase or three-phase electricity meter with the radio control module installed in it. With the help of this module, the consumer of electric energy has the opportunity to disconnect the pecking motor of the electric meter. These actions are allow you not take into consideration actually consumed elecrtrical energy. This module is installed by the consumer illegally and when a network organization detects this , they make an act about unaccounted electric power consumption. The method is based on the measurement of the intaking power of the volt circuit by the maser gage CE601 of the analyzing counter of electrical power CE 101, with the mechanical counting mechanism. Herewith, the consumer's loading is switched off by supply feeders. This method is allow to draw the conclusions about the presence of embedded non-factory devices without disconnecting of the electricity meter from the network ( time saving ).
