The action of illumination on the conducting and dielectric properties of lead magnoniobate was investigated. The photostimulated currents were examined and the spectral dependence of photoconductivity in the region of diffuse phase transition was obtained. It was found that the illumination affects the dielectric properties and that its action is memorized at temperatures below room temperature. The role of defect states in the formation of relaxor properties is discussed on the basis of the obtained data. 相似文献

The formation of polytypic modifications is observed in dislocation-free silicon single crystals under directional plastic
deformation. It is shown that the deformation-stimulated phase appears on the surface of the sample in the form of small grains
ranging from several hundred to several thousand angstroms in size. A twin structure in the individual grains is observed.

The results of experimental measurements of the hydrodynamic efficiency of laser plasma for aluminum and copper targets are presented. The studies were performed on the “Kanal-2” laser setup system using the ballistic pendulum method. The pressure in the interaction chamber was 10?4 Torr, the pendulum length was 145 mm, the mass of the pendulum with a target was 7.2 g. At the half-height pulse duration of 2.5 ns, the power density on the target surface was ~1013 W/cm2. In the case of aluminum target, the hydrodynamic efficiency coefficient increased from 1.5% to 4.5% with increasing laser pulse energy from 5 J to 10 J, whereas it remained at the level of 5% for the copper target. 相似文献

Influence of the Composition of Chloride-containing Solutions on the Corrosion of 12Cr18Ni10Ti Steel
Tereshchenko O. L. Likhachev V. A. Izotov M. V. 《Russian Journal of Applied Chemistry》2002,75(4):579-581
The corrosion activity of chloride-containing solutions formed in production of ternary nitrogen-phosphorus-potassium fertilizers was studied. The inhibiting effect of hydroxide ions on the corrosion of 12Cr18Ni10Ti steel during the evaporation of solutions of nitrogen-phosphorus-potassium fertilizers was evaluated. 相似文献

The magnetic properties of a ferromagnetic semiconductor based on indium antimonide doped with manganese and zinc having the Curie temperature T c = 320 K are studied. Field dependences of magnetization of InSb??Mn,Zn?? recorded at 4 and 260 K indicate that this material is magnetically soft with the coercive force no higher than 18 Oe at T = 300 K. 相似文献

Two polarization fluoroimmunoassays for the screening of amphetamine and methamphetamine in urine were adapted for use with the Abbott TDx-Analyzer running in the automatic mode. The detection limits of amphetamine and methamphetamine in 10 μl of urine were 0.03 and 0.05 mg l?1, respectively. These assays were specific for the determination of amphetamine (cross-reactivity with methamphetamine 1%) or for the determination of methamphetamine (cross-reactivity with amphetamine 2.5%). No significant cross-reaction was observed with other drugs of abuse (ephedrine, morphine and butabarbital). 相似文献
