The electrical conductivity of aqueous LiIO3 solutions and solutions of the LiIO3-HIO3-H2O system is measured over a wide range of compositions at 25, 50, and 75°C. Isothermal surfaces of electrical conductivity are mapped, and the activation energies of conductivity are calculated. The conductivity isotherms in the LiIO3-H2O and HIO3-H2O boundary binary systems and in mixed solutions along sections with fixed electrolyte ratios each have a maximum as a function of electrolyte concentration. It is assumed that structure reorganization occurs in solutions in the concentration range corresponding to the peak conductivity. Proton migration features in the solutions in question are considered. 相似文献

For second-order quasilinear degenerate elliptic equations, having the structure of
-elliptic equations in a bounded domain Rn, n2, one establishes theorems of existence and uniqueness for the generalized solutions of the first boundary-value problem, bounded together with their A -derivatives of first order and also of first and second order. The case of linear second-order
-elliptic equations are separately considered.Translated from Zapiski Nauchnykh Seminarov Leningradskogo Otdeleniya Matematicheskogo Instituta im. V. A. Steklova AN SSSR, Vol. 115, pp. 83–96, 1982. 相似文献

The interaction of synthetic analogs of active centers of iron-sulfur proteins with phosphates of different structures was studied. It was shown that the process involves ligand exchange and obeys the first-order reaction kinetic equation. The most rapid exchange occurred with the most acidic compound diphenyl phosphate.A. E.

Structural mechanisms of formation of low-symmetry phases of cyanospinels are described in terms of the phenomenological theory
of phase transitions. These are examined for transitions from a spinel structure to two cubic
and four rhombohedral
phases, induced by automorphic irreducible representations 9-2 and 9-3. Atomic coordinates and the symmetry types of occupied
positions in asymmetric phases are determined. Criteria for discrimination between the two
as well as between the four
phases are formulated. The structures of complex cyanides Tl2Zn(CN)4
, K2Zn(CN)4, K2Hg(CN)4, and Rb2Hg(CN)4
are calculated. The displacements and irreducible representations inducing transitions from spinel structures to these phases
are determined.

The influence of phase transition (PT) on the process of thermal development of a latent image arising after X-ray and uv irradiation of ammonium perchlorate (AP) crystals has been studied. Despite the production of a large number of new dislocations accompanying PT, it essentially does not influence the thermal development: The developed image does not smear at PT, remaining as clear as before it. By comparing mirror-symmetric surfaces of cleavage planes of AP crystals, it has been shown that at doses of X-ray and uv irradiation sufficient for obtaining an image, no production of new dislocations was observed in AP crystals. It is suggested that latent image arises due to formation during irradiation of chlorine oxidic products of radiolysis: ClO3, ClO2, and ClO as well as the corresponding ions ClO?, ClO?2, and ClO?3, i.e., initiators of AP low-temperature decomposition. 相似文献
