- However, the most
commonly used form of
emissivity is the
hemispherical total emissivity,
which considers emissions as
totaled over all wavelengths, directions...
- Low
emissivity (low e or low
thermal emissivity)
refers to a
surface condition that
emits low
levels of
radiant thermal (heat) energy. All
materials absorb...
- Look up
emission in Wiktionary, the free dictionary.
Emission may
refer to:
Emission of air pollutants, notably: Flue gas, gas
exiting to the atmosphere...
- The
ratio of any body's
emission relative to that of a
black body is the body's
emissivity, so a
black body has an
emissivity of one. Absorptivity, reflectivity...
- A zero
emission engine, motor, process, or
other energy source emits no
waste products that
pollute the
environment or
disrupt the climate.

while having an
emissivity of 0.93. This is
because the
absorptivity is
averaged with
weighting for the
solar spectrum,
while the
emissivity is
weighted for...
-
ratio of the
actual emission to the
maximum theoretical emission is an object's
emissivity. Each
material has a
different emissivity which may vary by temperature...
- \varepsilon } is the

emission spectrum of a
chemical element or
chemical compound is the
spectrum of
frequencies of
electromagnetic radiation emitted due to
electrons making...
