A new microscopic model of anomalous muonium for the elemental semiconductors is proposed. The relevant configuration consisting
of both a diamagrentic molecule Si−Mu and an unpaired orbital e− is contained into a semivacancy of the real lattice. By using the unrestricted Hartree-Fock computational method the principal
properties of the system are established. A dynamical version of the model together with a question on the formation of such
system are discussed. 相似文献

We analyze the analog of the Kelvin-Helmholtz instability on the free surface of a superfluid liquid. This instability is
induced by the relative motion of superfluid and normal components of the same liquid along the surface. The instability threshold
is found to be independent of the value of viscosity, but turns out to be lower than in the absence of dissipation. The result
is similar to that obtained for the interface between two sliding super-fluids (with different mechanisms of dissipation)
and confirmed by the first experimental observation of the Kelvin-Helmholtz instability on the interface between 3He-A and 3He-B by Blaauwgeers et al. (cond-mat/0111343). 相似文献

Mössbauer studies in murine (MEL) and human K-562 erythroleukemia cell lines have been utilized to study the fate of iron during intracellular Hb synthesis and denaturation. The results showed that ferritin can serve as an intermediate iron pool for Hb synthesis and for storage of iron released during intracellular Hb denaturation. 相似文献

A Green's function technique is developed for describing compositional ordering and vitrification of solid solutions with arbitrary composition. It is shown that the proposed approach is related with the standard theory of ordering of regular solid solutions. Peculiarities of the diagrammatic technique are studied. Explicit expressions are derived for the spectrum of solitary excitations, which are responsible for the ordering. Equations are derived for determining the temperature-concentration dependences of the compositional order parameter, the vitrification parameter, and the chemical potential.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 5, pp. 60–65, May, 1991. 相似文献

A numerical example of the salinity regime of soils in a two-dimensional region is considered with allowance for the effect of temperature fields. The mathematical model is based on solving a system of nonlinear partial differential equations.Translated from Vychislitel'naya i Prikladnaya Matematika, No. 60, pp. 59–65, 1986. 相似文献
