For the comparison, we assumed the same impact-vapor relation used in the previous sections (Eqs. (19) and (20)) for the asteroidal impacts.
The impact-vapor relation assumed in this paper (Eqs. (19), (20) and (27)) may overestimate the mass and/or the energy of the vapor cloud.
From the results of our preliminary experiments, which suggest that the existence of the wake is not an influential factor, the quantitative discrepancy would be primarily attributed to the impact-vapor relation that we used.
It should be noted that, even if our impact-vapor relation leads to an overestimation of the mass and energy of the vapor cloud, the scenario that the atmosphere decreases monotonically by impacts is less plausible because we tend to overestimate the effect of impact erosion.
The comparison results show that our model with the above impact-vapor relations (Eqs. (19), (20) and (27)) predicts a greater loss of atmospheric mass than that in Shuvalov and Artemieva (2002) by a factor of 150 300 for the asteroids and 1.2 30 for the comets.
Relations between vapor flux ratio and hydraulic parameters are less clear.
The structure of the material obtained was studied using light and scanning electron microscopy and its stability in relation to water vapor was examined using a gravimetric sorption method with high-vacuum line.
It was found as a relevant aspect of mass transfer that the oxygen concentration in the carrier gas has a great influence on the vapor boundary layer thickness in relation to the homogeneous nucleation process.
The observed composition of the condensed nanoparticles sized above than ~10 nm depends on (a) the relations between the vapor pressures of the constituents of the alloy, (b) duration of the condensation process, (c) alloy composition and affinity of the constituents to oxygen, and (d) the conditions of storage and manipulation with the powder.
Among the powders under consideration, only the nanosized particles of Ni61.9Al38.1 alloy have the composition close to the composition of the master alloy (Fig. 6b), which could be explained by the particular relations between the vapor pressures of Ni and Al elements.
In this work, the adsorption equilibrium relations of the TCE vapor adsorption on activated carbons were elucidated as a function of various relative humidity.
