We investigate the solvability of one-sided contact problems with nonlinear boundary conditions. The results generalize the author's previous results to the case of equations in Lebesgue spaces.Translated from Vychislitel'naya i Prikladnaya Matematika, No. 66, pp. 77–83, 1988. 相似文献

The effect the method of preparation has on the formation, phase composition, porous structure, and catalytic properties of the 10% Ni-ZrO2 system during the partial oxidation of methane into syngas is studied. Stages of the formation of catalysts from precursors and the effect the method of preparation has on the phase composition, particle size, and catalytic properties of the active component during the partial oxidation of methane into syngas are investigated by means of synchronous TG-DTG/DSC and X-ray diffraction. The synthesis of a catalyst precursor via coprecipitation is shown to yield a monophase system with high nickel dispersion, catalytic activity, and stability. 相似文献

The methods of fractional thermoluminescence and thermally stimulated currents are used to study the energy and kinetic parameters of trapping and recombination centers of pyrolytic boron nitride. Three types of monoenergetic traps with energies of 0.55, 0.85, and 1.05 eV are detected against the background of a quasicontinuous distribution of additional levels. A scheme of recombination processes is put together on the basis of measurements of the sign of the carriers, x-ray luminescence, and thermoluminescence spectra. The correlation of the activation energies, frequency factors, and the luminescence and conduction distributions confirmed that an electron-hole mechanism is responsible for the electrotransport with a predominant contribution from holes.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 11, pp. 72–76, November, 1989. 相似文献

The primary products of irradiation of alkali halide crystals are anion and cation Frenkel pairs [1–4]. Interaction of these products among themselves and with structural defects existing before irradiation leads to the appearance of various structural defects, the majority of which are optically active. The present study will treat enrichment centers which can be formed from the components of Frenkel cation pairs. Studies of this type are important in providing information on states in which radiation-created cation defects can exist stably in the lattice.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 8, pp. 119–121, August, 1979. 相似文献

Oxide systems supported by -Al2O3 and MgO were studied in oxidative dimerization of methanol. The highest selectivity is exhibited by tin oxide promoted with Na2O and La2O3 supported by magnesium oxide. Reactions of partial oxidation and etherification of methanol and ethylene glycol proceed on this system to the same extent as dimerization of methanol to ethylene glycol. 相似文献

Effect of a microwave field on metallic catalysts was studied in the reaction of decomposition of methane into hydrogen and
highly dispersed carbon. The dependence of the conversion of methane, yield of carbon, and its composition on the chemical
nature of a catalysts and reaction conditions was examined. 相似文献
