Conclusions According to the experience gained in erecting the upstream concrete-transport trestleway during construction of the Zeya
hydroelectric scheme, in order to reduce labor consumption, the demands for crane time, and the erection period, and to improve
conditions for safety, it can be recommended where similar trestleways are being erected that: a) maximal subassembly of the
units to be erected should be carried out at subassembly bases not more than 5 to 10 km distant; b) connection of the units
being erected should be made with highstrength bolts tightened by calibrated dynamometric wrenches; c) the Zeya method of
supporting the pylons should be applied; d) special two-jib units should be used for erecting the heaviest crane-runway girders.

We present a new peak-detection algorithm based on the method of 'minimum average risk' proposed by Kolmogorov and developed for signal processing in various fields. In this method, translations of features within a signal scan are quantified by minimizing the integrated pointwise product of each scan relative to the first derivative of the immediately previous scan. We have adapted this method for use in a new algorithm to monitor dynamic changes of sarcomere length in single myofibrillar sarcomeres of striated muscles, but the algorithm can also be used more generally for peak localization. We find that this method results in sub-nanometer precision and higher signal-to-noise ratio than current methods. At an equal noise level, the RMS deviation of the minimum average risk algorithm was 1.3 times lower than that of the center of mass method with modeled data and 3-4 times lower with actual data. 相似文献

The results of an experimental study of the effect of air oxidation on the temperature dependence of the heat capacity and normal spectral emissivity (for the wavelength of 0.65 m) of the zirconium alloy E635 (1.3 mass% Sn, 0.3 mass% Fe, 1 mass% Nb) are presented. The subsecond resistive pulse heating technique has been used. The samples were heated in ambient air by single and multiple cyclic pulses. 相似文献

The formation of Ge nanoclusters in bulk and thin-film germanosilicate glass samples prepared by vapor deposition techniques and then heat-treated in molecular hydrogen at 800°C was studied by Raman scattering and optical spectroscopy. The results demonstrate that the formation of Ge nanoclusters is accompanied by a substantial increase in the concentration of oxygen-deficient germanium centers and the formation of OH groups. A mechanism of nanocluster formation is proposed. The effects of different process parameters on nanocluster growth in the course of preform fabrication and fiber drawing are examined. 相似文献
