Blackbody is a standard for the calculation of radiative heat transfer. It can not only absorb 100% of incident radiation energy, and on top of it, and it also has the ability to radiate maximum (100%). The so-called blackness, is refers to the object approaches the blackbody, but also refers to the ratio of radiation radiation ability of the object with the same temperature blackbody. Science provides blackbody blackness is 1, the remaining object blackness is less than 1. Blackness is usually expressed as a letter epsilon. If an object blackness is 0.8, that is to say the radiation ability of the object as the radiation ability under the same temperature blackbody 80%
