Thin-film nickel coatings on fiber materials 总被引:1,自引:0,他引:1

Vacuum deposition of thin films onto fiber materials is a promising method of obtaining electromagnetic screens. We have studied the structure and the electromagnetic properties of machine-knitted fabric coated with nickel by means of magnetron sputtering. When the fabric is irradiated from the metal-coated side, the reflection coefficient is higher by a factor of 1.4 as compared to the case when the same source of electromagnetic radiation is situated on the opposite side (facing the uncoated surface), while the absorption coefficient in both cases is the same. 相似文献

New-generation space thermionic nuclear power systems with out-of-core electricity generating systems 总被引:1,自引:0,他引:1
V. I. Yarygin V. I. Ionkin G. A. Kuptsov M. K. Ovcharenko V. A. Ruzhnikov A. P. Pyshko A. S. Mikheev D. V. Yarygin V. A. Evtikhin I. P. Bogush I. E. Lyublinskii A. N. Chumanov 《Atomic Energy》2000,89(1):528-540
The basic problems of the development of long service life thermionic nuclear power systems for space applications for supplying
power to transport power modules, intended for placing spacecraft in a geostationary orbit using electrorocket motors and
for providing prolonged operation of onboard systems for up to 10–15 years, are examined. Concepts for power systems with
multi- and single-element thermionic low-temperature energy-conversion systems, which are placed outside the reactor core
and in which heat is delivered to the emitters using molybdenum-lithium heat pipes at 1600–1670 K, are discussed as an example.
Computational results are presented for the electro- and thermophysical characteristics of electricity generating systems
and power systems with different variants of the design-technological solutions, including the possibility of increasing the
service life by reserving a part of the thermionic electrical power. The mass/size characteristics of the power systems with
basic variants of the systems are obtained and recommendations based on research and development work are made, 8 figures,
8 references.

A novel, alternative method for acid rock drainage (ARD) remediation and metal recovery has been developed that uses a peat-humic agent (PHA) created by mechanical, chemical, and thermobaric treatment of peat from the Krugloe deposit (Novosibirsk region, Russia). The PHA effectively neutralised moderately acidic ARD and removed potential pollutants (e.g. Fe, Al, Zn, Cu, Pb, Cd, Ni, Co, and Hg), forming metal–organic residues. The organic matter can be removed completely from the metal–organic residues by heating them at 450–500 °C. After this treatment, the metal concentrate residues generally contained aggregates (20–350 μm in size), mainly composed of metal oxides and sulphates. Thermal decomposition of the organic matter in the PHA and metal–organic residues is an exothermic process with significant calorific value (9–15 kJ/g). 相似文献

Conclusions The article presents the results of psychological experiments studying the processes of solution of transformation problems. The approach is based on a number of principles for organizing an active search of an efficient problem-solving technique in the given class.An efficient strategy has been identified for the class of transformation problems (the integrative strategy) and the main principles, and rules and psychological features of this strategy have been described.We have analyzed the perception of the problem space for subjects who followed the efficient integrative strategy as well as the organization and representation of the knowledge of the knowledge necessary for attaining the final goal.The results of the psychological study point to possible improvement of the problem-solving algorithm.Translated from Kibernetika, No. 3, pp. 105–111, May–June, 1986. 相似文献

Gaussian field expansions for circular aperture antennas are reviewed, and a method for finding optimal scales in these expansions is given, paralleling the method for rectangular antennas presented in an earlier paper. This procedure is shown to lead to approximations structured in the sense that the number of lobes in the approximation corresponds to the number of terms retained in the expansion. An example is given of the development of a cosine distribution from the aperture, through the Fresnel region, to the far field. 相似文献

The authors studied the adaptation of initial and final links of the proteolytic chain, and intermediate nitrogen metabolism, to unusual products--protein concentrate from yeast-saccharomyces and anchovy. A number of enzymes in the organs-producers were found to be activated due to intensification of a limited proteolytic reaction. It was established that the changes in the functioning of the proteolytic stage of the digestive-transport conveyor led to shifts in the amino-acid pool in the blood serum of experimental animals. 相似文献
