A greater amount of infrared radiation implies a larger amount of cooler material surrounding the star, which indicates that it is still coalescing. 紅外線(xiàn)輻射越是強烈，表示星體周遭有越多溫度較低的物質(zhì)，也就是說(shuō)這個(gè)星體還在形成階段的初期。
Radiative forcing is defined as a change in average net radiation at the top of the troposphere tropopause due to a change in either solar or infrared radiation. 輻射力的定義是由于太陽(yáng)或紅外線(xiàn)輻射份量的轉變而引致對流層頂部的平均輻射改變。
