Interaction of slow electrons with surface: Empty electronic states and inelastic scattering effects

The fine structure of experimental true secondary-electron emission spectra along the normal to a clean W(1 1 0) surface, target (or total) current spectra, and low-energy-electron-transmission spectra along the normal to a clean 2H-MoS₂(0 0 0 1) surface are interpreted theoretically. It is shown that the fine structure of these spectra is mainly due to the electronic structure of unoccupied high-level electronic states (above the vacuum level), which become occupied by electrons entering the solid. In addition, a comparison to existing theoretical and experimental data is given.     

Pulsating motion of a liquid in capillaries under the influence of a force field

The substantial influence of an inhomogeneous electric field on the processes of mass exchange in capillaries that are a pore-structure model has been found. It has been established that the electromigration of nonequilibrium films and capillary-liquid columns to the evaporation surface is observed in the region of large field gradients. __________ Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 79, No. 5, pp. 20–25, September–October, 2006.

Test rig for measuring the center of gravity coordinates and inertia tensor of spacecrafts: Data acquisition and control system

We consider data acquisition and control system used in the test rig for measuring the center of gravity coordinates and inertia tensor of spacecrafts. Structure of the system is described. Technical specifications and metrological parameters are presented for the module which measures static and dynamic signals of strain gauge dynamometers and for the module which measures the signals of angular oscillation sensor installed on the test rig measuring platform; these oscillations are generated using electric motors and special control hardware. Finally, we describe the system software used to acquire and process the data and to display the measurement results.     

Investigation of optical characteristics and particle-size distribution of wood-smoke aerosols

The microstructure and optical characteristics of wood-smoke aerosols are studied as a function of the combustion regime, smoke-formation intensity, aging with time, artificial change in the relative air humidity, and particle temperature by the methods of polarization nephelometry, photoelectric counting, and electron microscopy. A three-fractional model of the particle-size distribution is proposed, and the role of each fraction in the stages of smoke formation and further changes is justified. It is shown that the governing factor for the formation of strongly absorbing particles (black-carbon content) is a combustion regime. The absorption parameters and the content of volatile components in black-carbon particles are estimated.Translated from Fizika Goreniya i Vzryva, Vol. 32, No. 5, pp. 122–133, September–October, 1996.
