Txoj Cai Ntawm Dub Lub Cev Tawg Ntawm Qhov Ntsuas Tshaj Tawm Ntsuas Ntawm Cov Ntsuas Hluav Taws Xob

Lub cev dub yog tus tsim hluav taws xob radiator. Nws nqus tag nrho cov kab hluav taws xob ntawm lub zog radiant, tsis muaj lub zog xav txog lossis xa mus, thiab nws saum npoo muaj emissivity ntawm 1. Nws yuav tsum tau taw qhia tias tsis muaj lub cev dub tiag tiag hauv xwm, tab sis txhawm rau kom meej thiab tau txais kev faib tawm ntawm infrared hluav taws xob , tus qauv tsim nyog yuav tsum raug xaiv nyob rau hauv kev tshawb fawb theoretical. Qhov no yog qhov ua kom muaj nuj nqis oscillator tus qauv ntawm lub cev kab noj hluav taws xob tau npaj los ntawm Planck, uas yog los ntawm Planck txoj cai ntawm lub cev dub hluav taws xob, uas yog, lub teeb ci ntsa iab ntawm lub cev dub qhia hauv yoj yoj yoj, yog qhov pib ntawm txhua qhov duab hluav taws xob infrared yog hu ua txoj cai ntawm dub lub cev hluav taws xob.

Qhov cuam tshuam ntawm cov khoom tawm mus los ntawm kev ntsuas hluav taws xob ntsuas: cov khoom tiag tiag uas muaj nyob rau hauv cov xwm yuav luag tsis yog lub cev dub. Ntxiv rau qhov hluav taws xob yoj hluav taws xob thiab qhov kub thiab txias ntawm qhov khoom, qhov ntsuas hluav taws xob ntawm txhua qhov khoom siv tseem muaj feem xyuam rau cov khoom siv xws li cov khoom siv uas tsim cov khoom, cov txheej txheem npaj, txheej txheem thermal, thiab cov txheej txheem saum npoo thiab thaj chaw ib puag ncig Cov. Yog li, txhawm rau ua kom lub cev dub lub cev hluav taws xob muaj feem xyuam rau txhua yam khoom siv, ib qho kev faib tawm ntsig txog cov khoom ntawm cov khoom thiab lub xeev lub xeev yuav tsum tau tshaj tawm, uas yog, emissivity. Cov pa roj carbon monoxide no qhia txog yuav ua li cas kaw qhov hluav taws xob thermal ntawm qhov tseeb kwv yees rau hluav taws xob dub, thiab nws tus nqi yog nruab nrab ntawm xoom thiab tus nqi tsawg dua 1. Raws li txoj cai ntawm hluav taws xob, ntev li ntev los ntawm emissivity ntawm cov khoom tau paub, infrared tawg cov yam ntxwv ntawm txhua yam khoom tuaj yeem paub.

Lub hauv paus tseem ceeb cuam tshuam emissivity: cov khoom siv hom, sab saum npoo, lub cev thiab tshuaj qauv thiab cov ntaub thickness.

Thaum ntsuas qhov ntsuas kub ntawm lub hom phiaj nrog qhov ntsuas duab hluav taws xob infrared, ua ntej ntsuas ntsuas duab infrared tawg ntawm lub hom phiaj hauv nws pawg, thiab tom qab ntawd qhov ntsuas kub ntawm qhov ntsuas lub hom phiaj yog ntsuas los ntawm tus pas ntsuas kub. Tus pas ntsuas kub monochromatic yog sib npaug rau cov hluav taws xob hauv cov xov paj; ob-xim tus pas ntsuas kub yog sib npaug rau tus piv ntawm cov hluav taws xob nyob hauv ob txoj xov.
