Abstract
The certified reference materials (RM) of the thickness of bilayers of Langmuir-Blodgett PbSt2 films on the quartz substrate for calibration of small-angle X-ray diffractometers used for certification and standardization of nanoindustry productions were developed.
LINEAR AND ANGULAR MEASUREMENTS
31-34 82
Abstract
An improvement procedure for the universal sets of plane-parallel end measures widely used in various branches of mechanical engineering is suggested. On the base of the existing sets of end measures analysis an original algorithm of design of universal sets with improved characteristics ensuring the convenience of operation is developed.

Abstract
The design versions of contactless sine-cosine angle sensors and the existing data ware solutions of positioning based on electromechanical transducers are considered. The description and characteristic of cyclic and tracking displacement transducers with open, closed and variable structures are presented. The application limitations are demonstrated.
OPTICOPHYSICAL MEASUREMENTS
44-48 76
Abstract
The theoreticalprocessing of current-voltage characteristics ofHamamatsu S6337 and S1336 photodiodes by least squares method for internal quantum efficiency determination is carried out. A new method of experimental curves processing with use ofreference points is purposed. By means of comparison of trap detectors built on the S6337photodiodes, and certified in PTB the experimental value of internal quantum efficiency of Hamamatsu S6337photodiode is obtained. The discrepancy between theoretical and experimental values was 0,1%.
