Emissivity
| Глоссарий по теории волн |
- The ability of an object to radiate and absorb energy from its surroundings measured as a ratio of the actual object emission to the blackbody equivalent emission
- The ratio of the radiant energy emitted by any source to that emitted by a blackbody at the same temperature.
- Коэффициент излучения
- The ratio of radiation emitted by a surface to the radiation emitted by a blackbody at the same temperature.
- The energy emission rate usually expressed as r/c/hr @ 1 ft or mr/mc/hr @ 1 ft.
- Variable ratio of the total energy radiated by a given surface at a given temperature to the total energy radiated by a blackbody at the same temperature. emissivity can be total, directional or hemispherical. emissivity is a surface phenomenon depending on surface condition and composition. smooth materials have lower emissivities than rough or corroded materials.1 emissivity values range between 0 for a perfect reflector to 1.0 for a blackbody.
