These monoliths are shown to be better for sensing molecules with smaller molar absorptivity, which are molecules that don t absorb into something very well.
32.
The model assumes that the average emissivity ( absorptivity ) is identical for either of these streams of infrared radiation, as they interact with the atmosphere.
33.
The total energy would be divided into three groups, they are called absorptivity ( ? ), reflectivity ( ? ) and transmissivity ( t ).
34.
If the radiating body and its surface are in thermodynamic equilibrium and the surface has perfect absorptivity at all wavelengths, it is characterized as a black body.
35.
In addition, c-BN consists of only light elements and has low X-ray absorptivity, capable of reducing the X-ray absorption background.
36.
The water absorption of aluminium and palladium becomes an unacceptable source of outgassing, and even the absorptivity of hard metals such as stainless steel or titanium must be considered.
37.
This is because the absorptivity is averaged with weighting for the solar spectrum, while the emissivity is weighted for the emission of the paint itself at normal ambient temperatures.
38.
For investigation of Kirchhoff's law of thermal radiation the notions of absorptivity and emissivity are necessary, and they rest on the idea of one-way radiation.
39.
However, it is typical in engineering to assume that a surface's spectral emissivity and absorptivity do not depend on wavelength, so that the emissivity is a constant.
40.
Where static air settles above an area of ground in the absence of wind, the absorptivity and specific heat of the ground strongly influence the temperature that the trapped air attains.
