The interaction of platinum(IV) and palladium(II) chloro complexes with the γ-Al2O3 surface in a wide range of surface metal concentrations is reported. Varying the concentration of the adsorbed metal complex
on the alumina surface causes changes both in the proportions of weakly and strongly bound desorbable platinum species and
in the proportions of desorbable (ion-exchanged) and nondesorbable (coordinatively bound) complexes. The adsorbed palladium
complexes are more uniform in chemical composition and binding strength and consist largely of desorbable species removable
from the surface by competitive sorption of anions. The absolute amount of coordinatively bound platinum and palladium species
increases as the total metal content of the sample is raised to 1.0% and remains almost invariable at higher metal contents. 相似文献

The double centralizing theorem between the action of the symmetric group Sn and the action of the general linear group on the tensor space Tn(W) was obtained by Schur. Here we obtain a double centralizing theorem when Sn is replaced by the wreath product of a finite group G and the alternating group An. 相似文献

We are concerned with the problem of uniform approximation of a continuous function of two variables by a product of continuous
functions of one variable on some domain D. This problem have been examined so far only on a rectangular domain D = U × V, where U and V are compact sets. An algorithm to give a solution of this problem in the discrete case is available. We put forward an algorithm
which in certain cases allows one to construct an approximate solution of the problem on a given domain (not necessarily rectangular).
This approximate solution is built in the form of interpolating natural splines, which in turn are constructed by means of
discrete approximation. Depending on the degree of the splines, the problem can be solved in classes of functions with appropriate
degree of smoothness. 相似文献

Experimental data on the evolution of macrodeformation fields of single-crystal samples of austenitic chromium-nickel steel
with a superequilibrium nitrogen content under tension are analyzed on the basis of a model of autowave plastic flow. The
conditions for the appearance and observation of different types of autowave deformation structures are established; such
structures include a solitary front, a traveling autowave, and a stationary dissipative structure and are determined by the
crystal-geometry of deformation and by the nitrogen concentration in the material. It is shown that a one-to-one correspondence
exists between the type of deformation autowave and the stage of the plastic flow curve of the material.

The dependence of deforming stresses, shape memory effect (SME), and superelasticity (SE) on the orientation of the single crystal axis, test temperature, and disperse particle size is examined for CoNiGa, NiMnGa, CoNiAl, FeNiCoTi, and TiNi single crystals. The orientational dependence of SME, SE, and temperature interval of the development of martensitic transformations (MT) under loading and SE is established. The influence of disperse particles on magnitudes of SME, SE, and mechanical hysteresis is discussed.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 9, pp. 4–20, September, 2004. 相似文献
