Cov ntaub ntawv ntawm emissivity
emissivity yog qhov sib piv ntawm lub zog ntawm lub zog ntawm qhov khoom tiag tiag rau lub zog radiant ntawm lub cev dub ntawm tib qhov kub, uas yog tus nqi tsawg dua 1. Nyob ntawm hom khoom, kub, yoj yoj, kev taw qhia, thiab cov xwm txheej sab nraud. Lub emissivity ntawm polished hlau nto yog tsawg, tab sis qhov saum npoo roughness lossis oxidation yog ho muaj kev txhim kho. Lub emissivity ntawm feem ntau lub tsev cov ntaub ntawv yog nruab nrab ntawm 0.8 thiab 0.95.
