The action of protons and electrons on the properties of glass strands under vacuum conditions has been experimentally investigated. The experimental procedure is described. The effects of irradiation, strain rate, and reduced temperature and pressure on the properties of glass reinforcement and glass-reinforced plastics are estimated.Institute of Mechanics, Academy of Sciences of the Ukrainian SSR, Kiev; Physicotechnical Institute of Low Temperatures, Academy of Sciences of the Ukrainian SSR, Kiev.

N.A. Vlasenko H.‐G. Purwins V.M. Popov I.A. Gumenyuk A.S. Klimenko Ya.F. Kononets F.‐J. Niedernostheide L.I. Veligura S. Zuccaro 《physica status solidi (a)》2002,194(1):237-243
A temperature (T) rise from 20 up to 80 °C results in some decrease of the threshold voltage and slope of the voltage (V) dependences of the luminance and the transferred charge of the electron‐beam evaporated ZnS:Mn ac thin film electroluminescent structures (ac TFELS) showing different patterns or no patterns in the emission. Such a heating leads to an improvement of the dynamics of all the patterns, to a narrowing and acceleration of the autowave (AW) front. However, the dynamic patterns are not formed by such a heat treatment if they are absent at any frequency of V and T = 20 °C. Although AWs more often take place at 70–80 °C, they have also been observed at T ≤ 40 °C in some samples. It has been concluded that heating is not a sufficient condition for the formation of patterns. It enhances the generation of initial free electrons at a given V, promotes a lateral spreading of the non‐equilibrium charge carriers, but decreases the rate of all processes responsible for the bistability of the TFELS and the self‐organization in them. 相似文献

Reversed-phase thin-layer chromatography plates can be effectively used for the separation of metal ions in low concentrations by classical low-voltage electrophoresis. Electropherograms of the ionic composition of hydrochloric and perchloric acid solutions of rhodium(III) and iridium(IV) were obtained. These electropherograms are comparable with the results of capillary electrophoresis. Special features of electrophoresis on reversed-phase plates were noted. 相似文献

The authors investigate the influence of certain aggressive media (toxic chemicals) on the wear resistance of filled epoxypolyamide composites. The presence of toxic chemicals in the zone of friction causes a sharp fall in the wear of the polymers. The maximum wear resistance is displayed by epoxypolyamide composites filled with iron powder, cement, or graphite. 相似文献
