emissivity

Preposition: of

• surface: Also given is a table of emissivities of common surfaces.
• body: Kirchhoff ) The emissivity of a body is equal to its absorbance at the same temperature.

Converse of object

• have: A perfect black body radiator has an emissivity of unity, so all other surfaces have emissivity between zero and one.
• glaze: Timber frame double glazed low emissivity coated windows, with a non-solvent stain are used throughout.
• measure: It also measured the radar emissivity, radar reflectivity, gravity and radio occultation data.
• calculate: In order to calculate an emissivity we first need to determine the transmitted and reflected components.
• assume: To alleviate such difficulties, it is common to assume a uniform emissivity over the entire wavelength spectrum.

Adjective modifier

• low: To remove the use of UPVc, softwood windows are used, with low emissivity double glazing.
• total: The spectral and total emissivity can then be calculated using the above equations.
• high: Blackbody lamps have a higher emissivity ( 0.99 ) and therefore can be used over a wider wavelength range and to higher radiance temperatures.
• independent: All measurement tools allow independent emissivity and distance settings.

Modifies a noun

• glass: Our eco house has double glazed windows with low emissivity glass.
• setting: Change color palettes, emissivity settings or temperature ranges.
• value: It is common among other ground-based telescopes to have emissivity values in excess of ten per cent.
• index: CO abundances relative to dust depend on the assumed temperature and hence on the dust emissivity index.
• film: In addition Llumar® performance low emissivity films will: Reject up to 69 % of unwanted solar energy.
• coating: The ideal position for the Pilkington K Glass low emissivity coating is on the inner pane facing the cavity.

Noun used with modifier

• surface: Differences arise due to simplifications in the treatment of surface emissivity, and also errors due to the treatment of cloud microphysics.
• dust: CO abundances relative to dust depend on the assumed temperature and hence on the dust emissivity index.
• telescope: No degradation of telescope IR emissivity, which is a crucial advantage for a system with strong science drivers in the infrared.
