ОБЩИЕ ВОПРОСЫ МЕТРОЛОГИИ И ИЗМЕРИТЕЛЬНОЙ ТЕХНИКИ

3-10 52
Abstract
Creation of data acquisition and control systems as combination of personal computer and ARM based microcontroller with additional circuits is considered. Separation of interface functions and interaction with control object provides hard real time mode, usability and low cost of complex. Description of practical implementation such system included.

ЛИНЕЙНЫЕ И УГЛОВЫЕ ИЗМЕРЕНИЯ

11-20 64
Abstract
The results of creating high-precision system for astronomical azimuth determination. The instrument composition, constructive features and algorithmic assurance have been considered. The results of azimuthal measurements accuracy estimation, confirming the instrument high precision characteristics are presented.
21-27 32
Abstract
The necessity of creation of more precise and productive instruments for measurement of sizes of boles and fruits of garden cultures is proved. The results of development and tests of portable contactless optical instrument «CALIBRE» for measurement of the garden cultures boles and fruits diameter are presented.

ОПТИКО-ФИЗИЧЕСКИЕ ИЗМЕРЕНИЯ

28-31 64
Abstract
A system of spatially arranged instruments representing a complex of laser-interference deformation measuring instruments has been developed and activated into the continious measurements mode.

МЕХАНИЧЕСКИЕ ИЗМЕРЕНИЯ

32-36 89
Abstract
Considered the possible additional errors of flow rate and amount of gas connection with the latest studios of discharge coefficient of standard orifices - have been considered.
37-41 38
Abstract
The instrument for measurement of rotor and face wear in which the optical system is realized on optical fibers is offered. The instrument parameters are estimated.

ЭЛЕКТРОМАГНИТНЫЕ ИЗИЕРЕНИЯ

42-46 43
Abstract
The operating principle of a sensor for density DC direct measurement in such physical media as liquid, gas and loose material is considered. The parameters of prototype with sensitivity of 1 mA/m2 are present.

МЕДИЦИНСКИЕ И БИОЛОГИЧЕСКИЕ ИЗМЕРЕНИЯ

47-52 61
Abstract
The external symptoms of mandibular joint diseases expressed in typical distortions of jaw movement trajectory have been studies. The procedure of dislocation and subluxation diagnostics using the three-dimensional measurement system based on photogrammetric technology has been proposed.

ФИЗИКО-ХИМИЧЕСКИЕ ИЗМЕРЕНИЯ

53-59 33
Abstract
The effect of neutralization on the results of particle size distribution measurement by the differential electric mobility (DEM) method by the example of SiO2 aerosol nanoparticles - has been studied. In is shown that in case of absence of particle charge neutralization the significant deviation of neutralized particles of measurement of nanoparticles concentration and sizes from the results of previously neutralized nanoparticles measurement - is observed.
60-68 54
Abstract
The procedure of Nickel alloys microwave sample preparation for mass fraction determination of Al, Ti, Cr, Co, Nb, Mo, Ru, Ta, W, Re by using inductively coupled plasma atomic emission spectroscopy (ICP-AES) is described. The compositions of dissolution mixtures and parameters of microwave digestion were chosen. The limits of relative measurement error for elements mass fraction from 0,1 % to 20,0 % do not exceed 4 % ( P =0,95).
