Sergey Alekseevich Khristianovich is one of the famous Russian mechanical engineers of the 20th century together with N.E.
Zhukovsky, S.A. Chaplygin, N.E. Kochin, and others. He made an immense contribution to some aspects of mechanics, such as
aerogasdynamics, rock mechanics, theory of plasticity, filtration theory, and environmental power engineering. All this was
preceded by a long, hard, and fruitful life full of outstanding events. 相似文献

The Fibonacci method is considered for stationary distributions. The initial postulates of this method are opposite to the postulates of statistical mechanics. The inapplicability of the hypothesis on identical dynamic particles is demonstrated on the example of the stationary state of a macromolecule in a thermostat. A new model of the stationary state of a substance is constructed based on the equality of chaos and order measures specified in terms of variables of three classes. The limiting transition from the new model to the well-known models is given. The law of evolution is expressed in terms of the symmetry of chaos and order. 相似文献

Main transport properties were studied for selective membranes with low dielectric constants based on liquid ion exchangers involving nitrogen-containing organic base cations. Permeabilities and ion flows through a membrane were calculated for major and interfering ions. Dependences of the transport properties of membranes on the concentrations of the ion exchanger and near-membrane solution and their potentiometric characteristics are presented. It was demonstrated that the transport properties of liquid membranes are determined by two main factors: the transfer of counterions through the phase boundary by the extraction–exchange mechanism and the leaching of the ion exchanger from the membrane. 相似文献

Specific models of domain walls are used to investigate conditions for the single-domain state and quasi-single-domain states
in structures with magnetic materials having a quality factor higher than one. It is shown that the critical thickness of
the magnetic film in a tangentially magnetized system decreases monotonically as the magnetizing field increases from zero
to the transition from the collinear to the homogeneous angular phase and then increases monotonically with increasing external
field. In a thin isolated magnetic film, the size of the domains increases exponentially with decreasing thickness. This dependence
is logarithmic near the transition to the single-domain state for a film coated on two sides and obeys a power law for a film
coated on one side. The establishment of a single-domain state and characteristic features in the asymptotic behavior of the
domain structure in magnetic films with and without coatings can be attributed to differences in the asymptotic behavior of
the field of a single domain wall.

The potentiometric response of ion-selective electrodes (ISEs) based on different lipophilic derivatives of tetraphenylborate to drotaverine hydrochloride was studied. The composition of a polymeric membrane was optimized to obtain the best electroanalytical properties of ISEs. The transport properties of selective membranes, the permeability and the flow of ions through the interface, were studied. Linear correlations between the solubility of ionophoric membrane components, membrane transport, and electroanalytical properties were revealed. The kinetic studies of ion-exchange adsorption showed that two limiting stages of transfer, namely, diffusion through the boundary layer and diffusion throug the membrane phase, occurred. Procedures for the potentiometric determination of drotaverine hydrochloride in pharmaceutical forms were proposed. 相似文献

The IR spectra of aminoalcohols in the gas phase show that in practically all instances (with the exception of N-allylaminoethanol) they are present mainly as monomers, with or without intramolecular H-bonds (IHB), the former predominating in the vicinal compounds. In 1,4-aminoalcohols the concentrations of molecules with and without IHB are practically equalized. The strongest IHB occur in the seven-membered intramolecular rings which are formed in 4-aminobutan-1-o1, for which the greatest difference is observed between the frequencies of the free OH groups and those bound in IHB. Analysis of the effect of an increase in temperature on the intensities of the OH bands of the free OH groups and of those bound in IHB shows that the partial rupture of the IHB occurs to a greater extent in the unsubstituted aminoalcohols of the vicinal series than in aminoalcohols with two alkyl substituents on the amino group. The IHB exhibit less tendency to break with rise in temperature in the vicinal aminoalcohols than in the 1,3- and 1,4-aminoalcohols.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 6, pp. 1323–1333, June, 1990. 相似文献

The potentials of electrochemical oxidation (
) and reduction (
) of monobromo- and isomeric di- and tribromo[2.2]paracyclophanes as well as
of mono-, di-, and tribromobenzenes were measured in acetonitrile. The similarity between the properties ofpseudo-para-disubstituted cyclophanes andmeta-disubstituted benzenes, on the one hand, andpseudo-meta-disubstituted cyclophanes andpara-disubstituted benzenes, on the other hand, was confirmed by the existence of a linear relationship between
of bromo-substituted [2.2]paracyclophanes and
of the corresponding bromo-substituted benzenes. The results were explained in terms of the qualitative theory of molecular orbitals, taking into account a through space interaction between the -systems of the benzene rings.Translated fromIzvestiya Akademii Nauk.
