The problem of estimation of the distance between two bodies of volume ε located inside an n-dimensional body B of unit volume is considered in the case n→∞. In some cases such distances are bounded by a function of ε not dependent on n. The cases when B is a sphere or a cube are considered. 相似文献

The chemical shifts and spin-spin coupling constants of the protons of the vinyl and ethyl groups and of the imidazole ring in the PMR spectra of complexes R4–n·SnXn · mB, where R=C2H5, C4H9;X=Cl, Br, I; B is N-vinylimidazole or N-ethylimidazole; and n=1 (m=1) and 2 (m=2), are compared. The electronic and geometrical structures of these complexes are discussed.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 3, pp. 391–394, March, 1973. 相似文献

An analytic solution is obtained for the problem of electron motion in an electron boundary layer along the surface of a conductor
in a static electric field. Calculations are made of the longitudinal conductivity near the surface in the limit of weak and
strong Coulomb nonideality of the layer electrons. It is shown that under certain conditions the boundary conductivity may
greatly exceed the conductivity in the bulk of the conductor.

A technological scheme for the recovery of lanthanides from phosphosemihydrate to obtain a nitrate solution was suggested. This scheme does not violate the balance of sulfuric acid and water, adopted in manufacture of extraction phosphoric acid. 相似文献

The vertical profiles of the aerosol attenuation and scattering coefficients are computed for the most prospective optical sounding wavelengths. The computations are carried out by exact formulas of Mie diffraction theory using experimental data about the microphysical nature of the continental aerosol. 相似文献

The PMR spectra of N-vinyl- and N-ethylimidazole were interpreted on the basis of an estimate of the broadenings and shifts of the resonance lines caused by the effect of an uncompensated electron spin of a paramagnetic complex. The site of coordination of N-vinyl- and N-ethylimidazole with NiCl2 was established.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 10, pp. 1416–1420, October, 1971.We thank Yu. N.
