Teb: Cov khoom uas tso cua sov dhau los ntawm lawv yooj yim yog hu ua cov khoom hluav taws xob zoo. Cov hlau zoo li tooj liab thiab txhuas muaj qhov thermal conductivity siab tshaj plaws thaum hlau thiab tooj liab muaj qhov qis tshaj. … Kub, Nyiaj, Hlau thiab lwm yam kuj yog ib co piv txwv ntawm zoo thermal conductors tshav kub conductors Fourier txoj cai
Txoj cai ntawm tshav kub conduction, kuj hu ua Fourier txoj cai, hais tias tus nqi ntawm tshav kub hloov los ntawm ib tug cov khoom yog proportional rau qhov tsis zoo gradient nyob rau hauv qhov kub thiab txias rau cheeb tsam, ntawm txoj cai kaum rau qhov gradient, los ntawm cov cua sov ntws. https://en.wikipedia.org › wiki › Thermal_conduction

as well as hluav taws xob conductors.
5 cov khoom siv hluav taws xob zoo yog dab tsi?
Qee cov ntaub ntawv tso cai rau cov cua sov ntws los ntawm lawv thiab lawv paub tias yog cov khoom siv hluav taws xob zoo los yog cov khoom siv hluav taws xob xws li hlau, txhuas, tooj liab, nyiaj, tooj dag, txhuas thiab stainless.
Yuav ua li cas yog ib tug zoo conductor ntawm tshav kub?
Silver yog ib qho zoo tshaj plaws ntawm cov cua sov, thaum stainless hlau yog cov neeg xyuas pib tsis zoo. Qhov tseeb, nyiaj yog ob zaug zoo li tus neeg xyuas pib zoo li txhuas, thiab ze li 10 npaug zoo li tus neeg xyuas pib raws li cov pa roj carbon tsawg. Tooj thiab kub tsuas yog cov hlau uas tuaj ze rau cov nyiaj hauv thermal conductivity.
Cov neeg ua haujlwm zoo yog dab tsi?
Ntau cov hlau yog suav tias yog cov khoom siv hluav taws xob zoo. Tooj liab tsuas yog ib qho ntawm cov khoom siv nrov tshaj plaws uas siv rau cov neeg siv khoom. Lwm cov ntaub ntawv uas qee zaum siv los ua cov khoom siv yog nyiaj, kub, thiab txhuas. … Aluminium thiab lwm yam hlau feem ntau tsis ua hluav taws xob zoo li tooj liab.
Puas yog cov khoom siv hluav taws xob zoo thiab hluav taws xob?
Metals yog cov conductors zoo (ob qho tib si ntawm tshav kub thiab hluav taws xob) vim tsawg kawg yog ib qho hluav taws xob ib atom dawb: piv txwv li, nws tsis khi rau ib qho atom tshwj xeeb, tab sis yog, Hloov chaw, muaj peev xwm txav tau yooj yim thoob plaws hauv cov hlau.
