(Nükleer Bilimler) emissivity
The energy-emitting propensity of a surface, usually measured at a specific wavelength
A measure of a surface's ability to emit long-wave infrared radiation or room temperature radiant heat energy Emissivity varies from 0 (no emitted infrared) to 1 (100% emitted infrared) The lower the emissivity, the lower the resultant U value
The property of emitting radiation; possessed by all materials to a varying extent
The ratio of total radiative output from a body per unit time per unit area at a specific temperature and wavelength to that of a black body under the same environmental conditions
the property of emitting heat radiation; possessed by all materials to a varying extent "Emittance" is the numerical value of this property, expressed as a decimal fraction, for a particular material Normal emittance is the value measured at 90° to the plane of the sample, and spherical emittance is the total amount emitted in all directions We are generally interested in spherical, rather than normal emittance Emittance values range from 0 05 for brightly polished metals (aluminum) to 0 96 for flat black paint Most nonmetals have high values of emittance
the fractional value between 0 and 1 that indicates how closely an object or surface approximates a perfect blackbody radiator, with 1 being a perfectly emitting blackbody This is a parameter used in radiative transfer modeling to characterize radiative properties of surfaces such as soil, rock, water, clouds
The ratio of energy emitted by a material to that which would be emitted by a blackbody at the same temperature
Tendency to emission; comparative facility of emission, or rate at which emission takes place, as of heat from the surface of a heated body
Symbol ?, a special case of exitance for a material with a specular surface and is opaque
relating to windows, the ability of the glazing to allow radiation to pass through it
the actual emittance of a radiating surface expressed as a fraction of the blackbody value for the surface temperature
The ratio of energy emitted by an object to the energy emitted by a blackbody at the same temperature The emissivity of an object depends upon its material and surface texture; a polished metal surface can have an emissivity around 0 2 and a piece of wood can have an emissivity around 0 95
The ratio of the radiant energy emitted by a source to the radiant energy of a perfect radiating surface (black box) having an equivalent surface area with all other relevant conditions being the same
  The ratio of power radiated by a substance to the power radiated by a blackbody at the same temperature (188)
(sol) The ratio of RADIANT ENERGY emitted by a body to that emitted by a perfect BLACKBODY A perfect blackbody has an emissivity of one; a perfect REFLECTOR, an emissivity of zero F - emissivite S - emisividad
the ratio of radiant energy from a material to that from a blackbody at the same kinetic temperature Materials may have wavelength-dependent emissivities between 0 and 1 0 (approximately the inverse of reflectance)
{i} ability to emit (Physics)
The ratio of the radiation emitted by a surface to that emitted by a black body at the same temperature (Source: Carbon Dioxide Information Analysis Center, 1990)
the ability of a surface to emit radiant energy compared to that of a black body at the same temperature and with the same area
