单词 emissive
释义

Definition of emissive in English:

emissive

adjective ɪˈmɪsɪvəˈmɪsɪv
technical
  • Having the power to radiate something, especially light, heat, or radiation.

    Example sentencesExamples
    • A more quantitative approach on absorption and emission of radiation in terms of absorptive power and emissive power are explained with specific references to block - body radiation.
    • This is rapidly improving, as wider gamut decoders are released, but these types of emissive displays will have trouble approaching the low-light detail of CRTs for some time to come.
    • With only one emissive species the fluorescence anisotropy should not change over the emission band belonging to a particular electronic transition.
    • A second prerequisite for observing fluorescence depolarization from a CT complex is that the complex is emissive.
    • Since the PDP is emissive (produces its own light), the amount of light it emits can be flexibly regulated according to the use environment.
    • The fact that biexponential fits are always required shows that different emissive species are present in the samples.
    • While the reflective and emissive properties of a roof are most important for its coolness, other factors such as insulation, roof orientation and roof pitch contribute to a building's overall thermal efficiency.
    • It should also be possible to use an emissive polymersome vesicle to transport therapeutics directly to a tumor, enabling us to actually see if chemotherapy is really going to its intended target.
    • A reflective and emissive roof system reduces both internal heat loads and the building's contribution to the ‘urban heat-island’ effect.
    • These television displays use a phosphor coating as the emissive medium, but do not rely on a single electron gun, as with CRT displays.

Derivatives

  • emissivity

  • noun iːmɪˈsɪvɪtiˌɛməˈsɪvədi
    technical
    • These variations between the two bands depend on emissivity and reflectivity of the materials that make up the target and/or background.
      Example sentencesExamples
      • Low emissivity (low-e) glass has a special surface coating to reduce heat transfer back through the window.
      • This is because metal performs well when it comes to both emissivity and solar reflectivity.
      • The material's ceramic components exhibit the property of high emissivity, which means the material tends to radiate heat.
      • This inversion technique takes into account atmospheric effects on the radiation and spatial variations in the surface emissivity and backscatter.
      • Because of the lower roof surface temperature on roofs with a high emissivity and high reflectivity, urban heat islands can be reduced with widespread use of cool roofs.

Origin

Mid 17th century (in the sense 'that is emitted'): from Latin emiss- 'emitted, sent out' (from the verb emittere) + -ive.
