Muaj peb lub ntsiab txheej txheem lub luag haujlwm rau lub zog thauj : hluav taws xob diffusion, conduction thiab convection, tag nrho cov tsav los ntawm radial kub gradient los ntawm qhov chaw mus rau saum npoo.
Ib yam li ntawd, yuav ua li cas yog lub zog thauj mechanism?
Zog Thauj • Muaj peb qhov ua tau mechanisms rau lub zog thauj los ntawm ib qhov chaw mus rau lwm qhov: conduction, hluav taws xob, thiab convection. • Kev coj ua yog kev hloov ntawm zog nyob rau hauv ib yam khoom los ntawm kev sib tsoo ntawm atoms thiab / los yog molecules.
Radiative Transfer Model yog dab tsi? Radiative hloov cov qauv piav qhia txog kev sib cuam tshuam ntawm cov canopy thiab xwm txheej hluav taws xob tau tsim los ntawm cov hloov mechanism ntawm hluav taws xob los ntawm ib tug turbid nruab nrab. Hauv cov no qauv , lub canopy yog assumed yuav horizontally uniform, nrog dav hlau parallel sib txawv khaubncaws sab nraud povtseg, saum toj no ib tug kab rov tav av nto.
Ib tug kuj yuav nug, lub zog thauj hauv lub hnub li cas?
Zog yog generated los ntawm nuclear fusion nyob rau hauv lub Lub hnub kub, ntom, high-pressure core. Convection: zog yog thauj los ntawm qhov loj-loj ncig 'convection currents', raws li cov kua dej kub nce thiab cov kua dej txias. Radiative Diffusion: zog yog thauj los ntawm photons ntws los ntawm sov, kaj cheeb tsam mus rau txias, tsaus cheeb tsam.
Cov hnub qub hloov pauv zog li cas?
Txoj kev feem ntau ntawm lub zog thauj hauv qhov qub hnub qub yog los ntawm photons uas yog radiating deb ntawm lub tshav kub qhov chaw. In nruab nrab dimension hnub qub , txheej saum toj no hauv nruab nrab cheeb tsam, qhov twg cov tshuaj tiv thaiv nuclear yog nqa mus yog hu ua cheeb tsam ntawm thauj los ntawm hluav taws xob (nrog lub thickness ntawm 360.000 rau 410,000km ib

Cov kab hluav taws xob ua li cas qhia tias hluav taws xob muaj zog?
Lub zog ntawm cov hluav taws xob hluav taws xob nyob ntawm qhov chaw them nqi, tsis yog ntawm qhov kev xeem nqi. Ib kab tangent mus rau ib kab teb qhia txog kev taw qhia ntawm hluav taws xob ntawm qhov taw tes. Qhov twg cov kab teb nyob ze ua ke, cov hluav taws xob hluav taws xob muaj zog dua qhov uas lawv nyob deb
Lub zog hluav taws xob hloov hluav taws xob li cas?
Tab sis yuav ua li cas qhov no ua hauj lwm nyob rau hauv cov nqe lus ntawm circuits? Qhov hluav taws xob muaj peev xwm hloov pauv mus rau lub zog hluav taws xob li niaj zaus thaum cov hluav taws xob txav mus los ntawm lub voj voog. Tom qab ntawd, lub zog hluav taws xob tau xa mus rau cov khoom hauv Circuit Court. Yog hais tias lub voj voog muaj lub teeb, nws tawm los ua lub teeb lub zog thiab lub zog hluav taws xob tsis zoo
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Qhov twg hauv qab no qhia cov piv txwv ntawm tej yam uas hloov hluav taws xob hluav taws xob mus rau thermal zog?
Qhov twg hauv qab no qhia cov piv txwv ntawm tej yam uas hloov hluav taws xob hluav taws xob mus rau thermal zog? Ntxuam thiab cua turbine Toaster thiab chav tso cua sov Lub dav hlau thiab tib neeg lub cev Ntuj lub qhov cub thiab rab
