GENERAL PROBLEMS OF METROLOGY AND MEASUREMENT TECHNIQUES

8-10 69
Abstract
The way of an establishment of hypotheses justice of asymmetrical allocations based on their transformation to known symmetric allocations and analysis of information quantity, which the results of experiment contain, is considered.

НАНОМЕТРОЛОГТЯ

11-14 68
Abstract
A high-precision broadband monitoring system of multilayer dielectric coatings deposition has been created. An example of monitoring system application for manufacturing of antireflective coating with maximum reflectance 0.15 % in the spectral range 400–660 nm on vacuum unit VU-2M is presented.

MEASUREMENTS IN INFORMATION TECHNOLOGIES

14-18 80
Abstract
A system of characteristics of the results validity achieved at implementation of the measuring information technologies of control of products, production processes and systems, technical diagnostics and pattern recognition is suggested. At the same time the measuring information technologies are considered as the processes of objects classification.

LINEAR AND ANGULAR MEASUREMENTS

19-23 160
Abstract
The article describes further development of new approach to increase of geometric accuracy of multicoordinate NC-controlled systems based on optimal error correction strategy. Such systems are the basis of modern manufacturing. Similar design principles of both measuring and technological multicoordinate systems allow to use similar approaches for accuracy control, among them – approaches based on error correction. The volumetric geometric error correction in such systems based on laser measurements as well as approaches proposed by authors in previous articles and the accuracy improvement after error correction are considered.
23-27 96
Abstract
The experience in design of the series of modern domestic plate–measuring engines including those with submicrometer accuracy – is described. The technical characteristics, design solutions and the software peculiarities are considered.
32-35 70
Abstract
The results of development of domestic measuring complex for automated instrument adjustment outside the machine tool for high-speed and high-precision manufacturing centers with programmed numerical control are presented. The information on features of measuring complex and on its capabilities and metrological characteristics is provided.

TIME AND FREQUENCY MEASUREMENTS

35-37 113
Abstract
The application of Kalman filter for measurements of frequency deviation and synchronization of high-stability generators by radio signals of space navigation systems have been considered. The estimation of filter operation errors is presented.

MECHANICAL MEASUREMENTS

37-39 60
Abstract
The relationships for determination of corrections to the storage capacity of vertical steel cylinder tanks due to a change of hydrostatic pressure of liquid column within the each tank ring limits are presented
40-43 86
Abstract
Thedevice for measurement of relative vibration of rotary engines shafts is considered. The parametric eddy current transformer is used as a sensor for clearance space measurement. Results of calculation of device characteristics are presented. The measuring circuit allowing to compensate the influence of initial parameters of the sensor and connecting line is suggested.
44-45 74
Abstract
A method of determination of the plastic sample porosity without special instruments based on measurement of its mass and volume and the volume of equal mass of the same material in grinded form is saggested.

RADIO MEASUREMENTS

45-49 113
Abstract
The dependences of the measurement error of the differential resistance of the non-linear two-terminal on the test harmonic signal level when using different types of AC/DC converters was obtained. It is shown that the smallest error is achieved with the use of half period average value converters. The numerical estimates of the example of a semiconductor diode are given.

MEDICAL AND BIOLOGICAL MEASUREMENTS

50-51 63
Abstract
The problems of verification and calibration of measuring instruments used in biological studies were considered. It is shown that the comparison of results of calibration by reference materials of composition and properties of substaces in solutions with the results of measurement of substances in living biological matrix is incorrect. The creation of certified reference materials based on biological matrices is proposed.
52-56 66
Abstract
The procedure of structural-frequency analysis of heart rhythm diagrams is suggested. A model of heart rhythm regulation is created. The interpretation of physiological terms is offered: «organism functional state»; «health» or «norm», «mechanisms of heart rhythm regulation and adaptation»; and also physical interpretation of the term «organism functional reserve» as informational-energetic base of adaptation mechanisms operation.
57-62 99
Abstract
The method and device for resonantmeasuring conversion of components of CG -dipoleprovidingreliable informationon thedielectriccharacteristics of aqueous solutions have been suggested.The experimental study resultsconfirming thecompliance of the developedtransmitter to requirements of systemsof control of compositionand structure of ion-moleculecomplexesof natural and wastewaters – have been presented.
