nanoporous structure on the movement of gas molecules can be ignored, and so the mean free path of gas molecules in the nanoporous material approaches the mean free path of gas molecules in free space, while the gaseous thermal conductivity approaches the gaseous thermal conductivity in free space...

This finding suggest that in the brain parenchyma of NPSLE patients a loss of tissue integrity occurs and facilitates motility of free water protons. By using ADC histograms, the loss of tissue integrity has been observed both in gray and white matter tissue separately [31]. Undoubtedly, one ...
Measurements are presented for the annihilation rates of thermalized positrons in a variety of substances, including noble gases, simple inorganic molecule... K Iwata,RG Greaves,TJ Murphy,... - 《Physical Review A》 被引量: 163发表: 1995年 Some remarks on the relation between free-volume fra...
From spectral moments of infrared vibration-rotation bands, the mean square torques are measured for CO2, N2O and C2D2 mixed with neon, argon and krypton and appear to be a linear function of the density up to 250 amagat. Above this density and up to 468 amagat, a departure from ...
For the gas near a solid planar wall, we propose a scaling formula for the mean free path of a molecule as a function of the distance from the wall, under the assumption of a uniform distribution of the incident directions of the molecular free flight. We subsequently impose the same ...
Based on the mean speed and mean free path theory of the molecule thermal motion, we obtain a mathematical formulation of the Reynolds stress by reasonable analysis and derivation. Results show that in the case of non rarefied gas flow, the Reynolds stress is inversely proportional to three ...
(helium) and I0 = 19.62 eV (H2), correspond to full configuration interaction results and are therefore the exact, non-relativistic theoretical values for the mean excitation energy of these two systems within the Bethe theory for the chosen basis set and, in the case of H2, at the ...
