Dab tsi yog qhov kev sib raug zoo ntawm cov thermal conductivity thiab ntub dej yam ntawm cov khoom rwb thaiv tsev?

Lub ntsiab lus ntawm Thermal Condivity: Feem ntau yog sawv cev los ntawm tus xeeb ceem "λ", thiab chav tsev yog hloov los ntawm · K tau hloov los ntawm ℃. Thermal conductivity (tseem hu ua thermal conductivity lossis thermal conductivity) yog kev ntsuas ntawm lub thermal conductivity ntawm cov khoom siv kub hloov chaw, cov khoom siv ntawm 1 'meter tuab, nrog a Qhov sib txawv ntawm 1 degree ntawm ob sab, hloov chaw kub los ntawm thaj tsam ntawm 1 thib ob). Nws qhia tau ib qho ntawm cov khoom siv nws tus kheej, thiab cuam tshuam nrog hom , xeev (roj, kua, khoom) thiab cov xwm txheej (kub, thiab lwm yam) ntawm cov khoom sib txuas hauv sab hauv ntawm ib koog gradient. Cov khoom sib txawv muaj ntau yam thermal conductivity tseem ceeb. Raws li rwb thaiv tsev cov ntaub ntawv muaj kev txhawj xeeb, ntau dua cov thermal conductivity, qhov tsis zoo ntawm rwb thaiv tsev rwb thaiv tsev kev ua tau zoo. Feem ntau hais lus, lub thermal conductivity cov khib nyiab yog loj dua li ntawm cov kua, uas ntau dua li cov roj av.

Lub tsev so ntub dej μ yog ib qho ntsuas tsis tau cov khoom muaj peev xwm tiv thaiv dej vapor nkag mus thiab yog qhov muaj dej dimyless. Chav tsev yog m, uas txhais tau hais tias nws yog sib npaug rau cov dej vapor permeability ntawm huab cua ntawm m. Nws piav txog cov khoom siv ua tau, tsis yog kev ua haujlwm ntawm cov khoom lossis cov qauv.

Rau rwb thaiv tsev cov ntaub ntawv nrog tib qho kev ua haujlwm ntawm thermal conductivity kμ, li cov thermal conductivity nce qeeb dua, thiab ntev dua nws yuav siv sij hawm mus cuag rwb thaiv tsev rwb thaiv tsev tsis ua hauj lwm , thiab lub neej ntev dua.
Thaum tus nqi μ tus nqi qis dua, cov thermal conductivity ncav cuag tus nqi tsis ua hauj lwm nyob rau hauv lub sijhawm luv luv vim kev nkag mus nrawm ntawm dej vapor. Yog li ntawd, tsuas yog ib txoj kev tsim tuab tuab tuaj yeem ua tiav tib qho kev pabcuam lub neej uas muaj cov ntaub ntawv muaj nuj nqis.
Jinfulai cov khoom siv cov tsev xauj tsev siab ntub kom ntseeg tau qhov hluav taws xob ruaj khov, yog li ib tug thinner pib tuab tuaj yeem ua kom lub neej pabcuam.
