    Notes: Abstract VUV spectra of a barrier discharge in a krypton-xenon mixture at the pressure P=400 hPa were experimentally studied. The xenon addition was varied in a range of 0.01–1%. The supply voltage frequency was 20 kHz. The form of spectra and their evolution at different xenon impurity concentrations were analyzed by solving the system of nonlinear differential equations simulating the main processes taking place in the active phase of a discharge and in the afterglow. The analysis supports the results obtained earlier and qualitatively describes the experimental spectra.

    Notes: Abstract A Mn-containing polymer was produced by solid-state photopolymerization of a cocondensated mixture of p-xylylene with Mn at 80 K. It was shown that during simultaneous deposition p-xylylene and Mn formed both σ- and π-complexes. Irradiation of the system by UV light resulted in polymerization of p-xylylene with the destruction of the unstable π-complexes, while the σ-bonded compounds were incorporated into the polymer chains. Complexes of Mn with benzyl-type radicals of the polymerized system were also observed. Prolonged storage of the polymerized material at ambient temperature under vacuum led to the gradual decomposition of the organomanganese compounds and complexes.

    Notes: Abstract The three-dimensional problem of energy exchange between translational and rotational degrees of freedom in collisions of diatomic molecules with structureless particles is solved numerically within classical mechanics. The intermolecular interaction potentials were taken as exponential repulsions between the molecular atoms and the incident particles, while well-known experimental information [1] was used for the potential parameters. The results obtained were used for numerical Monte Carlo evaluation of the collision integral, determining the rotational relaxation time. Molecular nitrogen is chosen as an example. The results of calculation are in quite satisfactory agreement with experimental data.

    Notes: Abstract The influence of a slow dissociation reaction (the reaction rate is much lower than the rate of energy exchange between the translational and internal degrees of freedom of the gas particles) on the transfer coefficients is studied using the Chapman—Enskog method. It is shown that changes occur only in the diagonal part of the pressure tensor, where an additional coefficient, the so-called relaxation pressure, appears.

    Notes: Abstract Considerable difficulties attach to the mathematical description of the motion of a system of spherical bubbles of identical dimensions in a liquid, at large Reynolds numbers. At present, there are several known approaches to the solution of the problem, based on the application of the cell model [1–4]. For small Reynolds numbers, a more rigorous description of a system of spherical bubbles was attempted in [5] by means of the Tam method [6], using the approximation of “point∝ forces with successive averaging over ensembles. In the present paper, the Tam method is used to describe the motion of a system of spherical bubbles of identical size at large Reynolds numbers. The drag force exerted by the liquid on a specimen bubble of the considered system is calculated.

    Notes: Abstract The effect of ionizing collisions on thermal conductivity λ is studied. A formal expression is obtained for λ with additional terms considering the presence of ionizing collisions in the gas. Calculations performed at p=1 atm and a temperature range of 10,000–25,000 °K show that the effect of ionizing collisions on translational heat capacity is not great. On the other hand, the presence of such collisions in the gas leads to a retardation of diffusion processes, which in turn leads to a significant reduction in the chemical component of the coefficient λ, with this reduction being strongly dependent on the choice of number of excited atomic levels realized in the gas.

    Notes: Abstract A disturbance of a quasiequilibrium distribution due either to a relaxation process or hydrodynamic perturbations can significantly influence the rate of the relaxation process in a gas. The expression for this rate then contains additional terms proportional to the spatial derivatives of the hydrodynamic variables [1–2]. According to the estimates of [2], the effect is clearly manifested in a nonequilibrium dissociating gas. The present authors have estimated [3] some of the additional terms in the initial stage of dissociation in a pure diatomic gas. In the present paper, expressions are obtained for the coefficients of the additional terms of the hydrodynamic equations in a dissociating diatomic gas for all dissociation laws. Estimates made for the example of oxygen show that the contribution of the additional terms to the hydrodynamic equations is comparable with the contribution of the ordinary Navier-Stokes terms.

    Notes: Abstract On the basis of the Chapman—Enskog method, a mathematical formalism of kinetic theory is developed for investigating transport phenomena in rarefied gases with allowance for an equilibrium dissociation reaction. The contribution of the dissociation collision integrals to the transport coefficients is estimated. The results of the estimate show that the presence of dissociation collisions in the gas does not have an appreciable influence on the coefficients of shear viscosity, thermal conductivity, and diffusion. On the other hand, the influence of the equilibrium dissociation reaction on the coefficient of bulk viscosity must be appreciable.
