The velocity of the chain explosivedecomposition reaction in silver azide whiskes has been measured (1500 m/sec). The measured velocity is identified as the propagation velocity of the diffusion front of holes generated in the course of explosive decomposition. 相似文献

1. | The design scheme of the 500-kV OEE of the Sayano-Shushenskoe hydrostation has a number of substantial shortcomings reducing the reliability of power output. Reconstruction of the middle network of the existing 4/3 scheme to three networks with two switches per connection is the most optimal variant of reconstruction. Sectioning of the collecting bus systems is necessary for a further increase of the reliability of the scheme. |
2. | In the case of repair works on equipment of small nonstandard switchgear, such as the 500-kV OEE of the Sayano-Shushenskoe hydrostation, it is necessary to use special equipment and mechanisms, the development of which must be recommended to domestic industry. |

The redox processes in ceramic and powder samples of α-Mn2O3 (kurnakite) and β-Mn3O4 (hausmannite) have been studied in the temperature range 20–1000°C. The results demonstrate that the conversion of α-Mn2O3 to β-Mn3O4 in the binary system Mn-O is essentially irreversible, even if there are nucleation centers in the form of the higher oxide α-Mn2O3 during the oxidation of hausmannite. It is shown that the high reactivity of hausmannite ground in a WC mill is not due to a mechanochemical effect. Grinding-induced contamination has a significant effect on the oxidation behavior of the system: the impurities incorporated into the sample during grinding in a mill favor complete (WC contamination) or partial (Fe contamination) conversion of hausmannite to kurnakite. Hausmannite contaminated with tungsten carbide oxidizes by a catalytic mechanism. In the case of Fe impurities, oxidation follows a solid-state mechanism, through the formation of restricted FexMn2?x O3 solid solutions. 相似文献

The relaxation ability of Zr46(Cu4/5Ag1/5)46Al8 and Zr46Cu46Al8 bulk glasses displaying different glass-forming ability (GFA) in the liquid state has been studied by measurements of the shear modulus, creep and stress relaxation. It has been found that the four-component alloy with higher GFA always displays higher relaxation ability in the glassy state. This fact does not seem to correlate with the amount of the frozen-in free volume as dependent on the GFA. It has been argued that the relaxation centers responsible for structural relaxation and related viscous flow are similar to dumbbell interstitials in simple metals. Such an approach precisely describes the kinetics of shear modulus relaxation and reasonably agrees with a phenomenological interpretation of structural relaxation-induced viscoelastic phenomena in metallic glasses. 相似文献
