Microclimatic measurements and lizard morphological measurements (size, absorptances
to solar radiation) were combined in an energy exchange model used to calculate an equilibrium temperature that the animal would attain under a given set of environmental conditions ([T.
53 kW) when the shade absorptance
was increased from 18% to 27% for a constant reflectance of 70%.
Addition of antireflection silicon dioxide coating increased the absorptance
To compare the calculated PBGs, we also give the plots of transmittance, reflectance, and absorptance
spectra as well.
They consist of a composite cover film with high emissivity and low visible absorptance
, and a low-emissivity surface adhered to the S/C.
Color does have a small effect on the absorptance
and emittance of the collector--black is best--but many architecturally pleasing colors such as darker blues, browns, and grays have been used with only a small penalty in efficiency.
In contrast, reciprocity failure was observed in a study of the solar absorptance
of space coatings by Olson et al.
Four correction factors were used: the LOCR window transmittance (TW), the LOCR receiver absorptance
(AR), the relative aperture transmittance (TA), and the LOCR electrical calibration (kL).
2001), the correlation of absorptance
of light with anthocyanin extracts and leaves from plants exposed to different levels of cold-induced photoinhibition (Pietrini & Massacci, 1998), and anthocyanin development in conjunction with the development of other mechanisms of photoprotection such as wax (Barker et al.
Both electrophysiological and behavioral data closely matched the normalized spectral absorptance
curve of a rhodopsin with [[lambda].
