The integrability conditions of the electromagnetic field equations in a continuum with defects and their wave solutions are found. The following dislocation effects on the electromagnetic wave propagation in a continuous medium are investigated: the change in the direction of the electromagnetic wave propagation in a continuous medium; the rotation of the polarization plane of electromagnetic field wave in a continuous medium; the excitation of longitudinal components of the electromagnetic wave in a continuous medium and the change in the electromagnetic wave intensity related to this phenomenon. The energy balance equation for the electromagnetic field in a continuum with a stationary distribution of dislocation is found and it is shown that an electromagnetic wave excites exciton modes localized at dislocations in the solid. 相似文献

The phase composition, electronic structure, and magnetic properties of nanostructures formed upon deposition of iron on the
surface of the Si(556) vicinal face coated by a submonolayer silver film with a √3×√3-Ag structure have been studied using
high-energy-resolution photoelectron spectroscopy and analysis of magnetic linear dichroism in photoemission of Fe 3p electrons.
The effective thickness of the deposited iron layer is varied from 1 to 25 ?. It has been shown that a 1- to 2-? Fe coverage
leads to the formation of a metastable iron silicide thin layer with a CsCl-type structure on the surface of the sample. A
further deposition of Fe (up to ≈7 ?) brings about the formation of chains consisting of nonmagnetic islands of the Fe—Si
solid solution on this layer, which are oriented along the steps of the substrate. A ferromagnetic alignment of the system
along the surface of the sample appears only at coverages of approximately 10 ?, when larger (≈100 nm) iron islands start
to grow on the solid solution layer. 相似文献

The structure of renormalization equations in gravitational theories with higher derivatives is considered. The gauge dependence of invariant divergences of the effective action is found to be nontrivial. The external source technique is used to construct a consistent Green's function renormalization. One- and two-loop divergences of the effective action are explicitly calculated for an arbitrary parametrization and gauge. These calculations fit the general structure of the obtained renormalization equations. Translated from Teoreticheskaya i Matematicheskaya Fizika, Vol. 121, No. 3, pp. 387–411, December, 1999. 相似文献

A study of the photocatalytic activity of commercial and mechanically activated zinc oxide powders has been carried out based on the example of the decomposition of Brilliant Green. The goal of this work was to study the effect of the grinding time (0, 1, 3, 5, and 7 min) on the structure of zinc oxide and its photocatalytic activity under visible and ultraviolet (UV) radiation. It has been found that, when UV radiation is used, the constant of the dye oxidation rate for samples activated for 1 min increases compared with unactivated powders, whereas further mechanical activation leads to a decrease in the photocatalytic activity. When using visible radiation, samples activated for 1 min showed the minimum photocatalytic activity and further mechanical activation led to an increase in the efficiency of photocatalysis. 相似文献

Based on the self-consistent cluster approximation of an effective medium for random walk over a lattice with stochastically positioned traps in the dispersion regime, the kinetics of the spectral relaxation of the partial populations was analyzed and the self-averaging of the diffusion coefficient was studied. It was demonstrated that the relaxation of partial populations at long time occurs anomalously slow, according to a power law. It was shown that, in the one-dimensional case, no self-averaging of the diffusion coefficient occurs even at long time (its fluctuation amplitude remain comparable with its value) and that in the two- and three-dimensional cases, self-averaging proceeds very slowly, in accordance with a logarithmic and power dependence, respectively. 相似文献

The quasi-isentropic compressibility of helium and deuterium plasmas at pressures of up to 1500?C2000 GPa has been measured using devices with spherical geometry and an X-ray diagnostic complex comprising three betatrons and a multichannel imaging system with electro-optic gamma detectors. A deuterium density of 4.5 g/cm3 and a helium density of 3.8 g/cm3 have been obtained at pressures of 2210 and 1580 GPa, respectively. The internal energy of a deuterium plasma at the indicated pressure is about 1 MJ/cm3, which is about 100 times greater than the specific energy of condensed chemical explosives. Analysis of the obtained data shows that the degree of helium ionization under the achieved plasma compression parameters is about 0.9. 相似文献

Cationic complexes [(diene)Co(??-C6Me6)]+ (diene is buta-1,3-diene (2a), 5-isopropyl-2-methylcyclohexa-1,3-diene (2b), cycloocta-1,3-diene (2c), and cyclohexa-1,5-diene (2d)) were synthesized by the reaction of [Co(??-C6Me6)2]+ (1) with dienes in a CH2Cl2-Me2CO mixture. In the absence of dienes, cation 1 undergoes hydrogenation to form [(1,2,3,4,5,6-HMCD-1,3)-Co(??-C6Me6)]+ (HMCD is hexamethylcyclohexadiene, 2e). Structures [2c?Ce]PF6 were determined by X-ray diffraction analysis. According to the DFT calculations, the Co-C6H6 bond in the complexes with conjugated dienes is stronger than that in the complexes with nonconjugated dienes. 相似文献
