Translation for 'opacity' from English to Russian

opacity

непрозрачность {ж}

• Black and white cards are used to measure both opacity and contrast ratio. By measuring reflectance values of both parts of the card one can gain a quantitative opacity value of a paint sample.
• With top layer opacity greater than that of the bottom layer, most pixels are taken from the top layer, while with low opacity most pixels are taken from the bottom layer.
• The small convective shell related to the opacity peak resulting from the ionization of iron group elements at about 200 000 K (iron opacity peak) could indeed be responsible for the stochastic excitation of acoustic modes like those observed in the Sun.
• A few years prior, Osterbrock proposed deep convection zones with efficient convection, analyzing them using the opacity of H- ions (the dominant opacity source in cool atmospheres) in temperatures below 5000K.
• Different processes can lead to opacity including absorption, reflection, and scattering.

• This equation shows how the effective optical depth in scattering-dominated systems may be significantly different from that given by the scattering opacity if the absorptive opacity is small.
• The thin walls cause the fibre to collapse upon drying, giving a paper with low bulk and low opacity.
• Initially soda glass was used with silver halide opacity.
• Harris Louis Mayer (born February 15, 1921) is an American physicist known for his collaboration with Edward Teller and John von Neumann. Opacity is generally calculated based on average opacities using Planck or Rosseland opacity functions.
• The lactoscope is an instrument for estimating the amount of cream in milk, based on its relative opacity.

• Alpha channels may be implemented in this way, where the alpha channel provides an opacity level to be applied equally to all other channels.
• When whitewash or limewash is initially applied, it has very low opacity, which can lead novices to overthicken the paint.
• Kramers' opacity law describes the opacity of a medium in terms of the ambient density and temperature, assuming that the opacity is dominated by bound-free absorption (the absorption of light during ionization of a bound electron) or free-free absorption (the absorption of light when scattering a free ion, also called bremsstrahlung).
• The evolution of the code has since involved better modeling of the line opacity (opacity sampling instead of opacity distribution functions), spherical modeling and including an increasing number of physical data.
• However, at a large enough radius, the opacity κ increases due to the decrease in temperature (by Kramers' opacity law), and possibly also due to a smaller degree of ionization in the lower shells of heavy elements ions.
