A model kinetic equation is constructed for the transport of a massless Bose gas. This equation is applied to solve the boundary
value problem for the transport of radiation in the half-space occupied by a dispersive medium that is in local thermal equilibrium
with the radiation. It is shown that the difference in temperature between the dispersive medium and the incident radiation
substantially depends on the character of the scattering properties of the particles in the medium.

A relaxation kinetic equation that describes the behavior of a Bose gas is derived. The Kramers half-space problem on isothermal slip is treated. An analytical solution and the number-of-particle distribution function for particles flying toward a wall, in explicit form, are obtained. The dependence of the slip velocity on the parameter that is the ratio of the chemical potential to the product of Boltzmann's constant by the absolute temperature is analyzed. The influence of the quantum effects on the isothermal slip coefficient is evaluated for He4. 相似文献

An analytical solution of the Poiseuille problem is obtained over a wide range of Knudsen numbers for the case when the tangential
momentum accommodation coefficients of the channel walls are much less than unity. An expression for the mass flux is derived
that is valid for Knudsen numbers much smaller than the reciprocal of the accommodation coefficients. A new intermediate flow
regime, for which the mass flux is given by an expression that differs from the classical (macroscopic) form, is found to
exist.

We set up model transport equations that describe the behavior of molecular (diatomic and polyatomic) gases with a molecule
collision rate proportional to the molecular velocity. In deriving these equations we allow for the internal (rotational)
degrees of freedom, while the vibrational degrees of freedom are assumed “frozen.” We also set up an exact equation for the
problem of the temperature jump with allowance for slow evaporation from the liquid surface into the saturated vapor atmosphere.
Finally, we derive explicit formulas for calculating the coefficients of the temperature jump and gas-density jump above a
flat surface and do the necessary numerical calculations.

A method for measuring the IR optical properties of metals, which implies the analysis of the angular distribution of the
photons emitted from the edge of a metal plate due to the conversion of thermal surface plasmons, has been theoretically and
experimentally shown. In this work an increased accuracy of the proposed method in the IR region is demonstrated in comparison
with more conventional methods based on the Fresnel formulas. This conclusion is supported experimentally with data obtained
from the surface impedance measurement of copper in the range from 8 to 9 μm at 185°C. 相似文献

The temperature dependence of the Aharonov-Bohm oscillations of small quasi-ballistic ring interferometers (effective radius R = 90–110 nm) is studied in a wide temperature range of (0.34–9) K. It is found that this dependence is determined not only by the size of the interferometer, but also by its microscopic state. It is shown that the effect may be associated with the influence of the fluctuation potential leading to different, but not completely stochastic, realizations of the scattering potential in conducting channels of the ring. 相似文献

The slip velocity of a rarefied gas with inhomogeneous temperature and mass velocity on a solid spherical surface is calculated with the use of a twomoment boundary condition in the linear approximation in terms of the Knudsen number. The dependence of the slip velocity on accommodation coefficients of the two first moments of the distribution function is studied. 相似文献
