Corpus analysis for Emissivity

  • In this selection, "emissivity" usually appears near the end of the sentence. The average example has 23.2 words, and this corpus slice is mostly made up of statements.
  • Around the word, usable, bulk, lower, values, independent and layers stand out and add context to how "emissivity" is used.
  • Recognizable usage signals include because its emissivity is low and determine local emissivity and albedo. That gives this page its own corpus information beyond isolated example sentences.
  • By corpus frequency, "emissivity" sits close to words such as aaronson, abai and abass, which helps place it inside the broader word index.

Example types with emissivity

The same corpus examples are grouped by length and sentence type, making it easier to see the contexts in which the word appears:

Short example sentences

The average emissivity of the earth is readily estimated from available data. (12 words)

Reflection and emissivity layers Aluminium is the common choice for the reflection layer. (13 words)

During the night, the atmosphere cools somewhat, but not greatly, because its emissivity is low. (15 words)

Longer example sentences

Wright, Appendix B. If some of the energy is absorbed, the absorbed energy will heat the sail, which re-radiates that energy from the front and rear surfaces, depending on the emissivity of those two surfaces. (36 words)

However, by definition, the radiation from a gray body is simply proportional to that of a black body at the same temperature, so its emissivity does not depend upon frequency (or, equivalently, wavelength). (33 words)

It also ignores other possible complications, such as changes in the emissivity with temperature, and the role of other accompanying forms of energy emission, for example, emission of particles like neutrinos. (31 words)

Example sentences (15)

Usable emissivity values are empirical because thin-film effects dominate; bulk emissivity values do not hold up in these cases because material thickness is much thinner than the emitted wavelengths.

A source with lower emissivity independent of frequency often is referred to as a gray body.

But added parameters are needed to determine local emissivity and albedo and address the factors that move energy about the earth.

During the night, the atmosphere cools somewhat, but not greatly, because its emissivity is low.

For example, it easily determines the effect on average earth temperature of changes in solar constant or change of albedo or effective earth emissivity.

For that reason, incorrect selection of emissivity will give inaccurate results when using infrared cameras and pyrometers.

However, by definition, the radiation from a gray body is simply proportional to that of a black body at the same temperature, so its emissivity does not depend upon frequency (or, equivalently, wavelength).

It also ignores other possible complications, such as changes in the emissivity with temperature, and the role of other accompanying forms of energy emission, for example, emission of particles like neutrinos.

Reflection and emissivity layers Aluminium is the common choice for the reflection layer.

See citation and citation citation citation citation Some authors describe sources of infrared radiation with emissivity greater than approximately 0.99 as a black body.

The average emissivity of the earth is readily estimated from available data.

The emissions by other bodies are treated in an empirical manner, relying on in particular the coefficient of emission ( emissivity ), which is determined by measurements.

The radiative-convective models have advantages over the simple model: they can determine the effects of varying greenhouse gas concentrations on effective emissivity and therefore the surface temperature.

To further explain, two objects at the same physical temperature will not show the same infrared image if they have differing emissivity.

Wright, Appendix B. If some of the energy is absorbed, the absorbed energy will heat the sail, which re-radiates that energy from the front and rear surfaces, depending on the emissivity of those two surfaces.
