Diffuse emitter yog a qhov chaw uas qhov kev siv hluav taws xob tawm hluav taws xob yog ywj pheej ntawm kev coj.
Thaum qhov chaw yog ib qho emitter diffuse Nws kuj yog specular?
Nyob ntawm seb hom ntawm qhov chaw, cov hluav taws xob uas cuam tshuam yog specular lossis diffuse. A du thiab polished nto yog specular ntauthaum lub ntsej muag ntxhib yog ntau dua. Ib feem ntawm qhov teeb meem lub zog nqus los ntawm qhov chaw yog hu ua absorptivity. Rau ib lub cev dub nws yog sib npaug rau ib.
Diffuser nto tshav kub hloov pauv yog dab tsi?
1. Diffuse nto: khoom yog ywj siab ntawm kev taw qhia. … Grey nto: cov khoom yog ywj siab ntawm wavelength. 3. Emissivity: txhais raws li qhov piv ntawm cov hluav taws xob tawm los ntawm ib qho chaw rau cov hluav taws xob tawm los ntawm lub cev dub ntawm tib qhov chaw kub.
Puas yog lub cev dub yog ib qho emitter?
Nws yog ib qho zoo tshaj plaws emitter: ntawm txhua zaus, nws tawm ntau los yog ntau dua thermal radiative zog ib yam li lwm lub cev ntawm qhov kub thiab txias. Nws yog ib qho diffuse emitter: ntsuas ib chav tsev cheeb tsam perpendicular rau cov kev taw qhia, lub zog yog radiated isotropically, ywj siab ntawm kev coj.
Diffuse Grey nto yog dab tsi?
Yuav ua kom cov kev ntsuas hluav taws xob yooj yim dua, peb txhais cov kev kwv yees hauv qab no: Diffuse nto: yog ib qho chaw uas nws cov khoom muaj kev ywj pheej ntawm kev coj. Grey nto: yog ib qhov chaw uas nws cov khoom muaj kev ywj pheej ntawm wavelength.
