Tib neeg kuj nug, dab tsi yog qhov zoo tshaj plaws conductor ntawm hluav taws xob thiab cua sov?

❖ Nyiaj yog tus neeg xyuas pib zoo tshaj plaws ntawm ob qho tib si kub thiab hluav taws xob ntawm cov hlau nrog tus nqi thermal conduction txog li 430 W / (mK). ❖ Kub & tooj liab ob leeg tuaj sib fwm nyob ze nyiaj . ❖ Nyiaj kuj muaj lub siab tshaj plaws thermal conductivity ntawm tej yam & lub siab tshaj plaws lub teeb reflectance.

Ib sab saum toj, cov hlau twg yog tus neeg xyuas pib ntawm hluav taws xob thiab cua sov? Hauv qhov no, hlau, zoo tus thawj coj ntawm kub thiab hluav taws xob . Yuav ua li cas cov ntaub ntawv muaj peev xwm ua tau hluav taws xob thiab cua sov yog vim cov dawb electrons tam sim no nyob rau hauv cov khoom. Hauv hlau, nws yog xim hlau kev sib raug zoo yog tam sim no.

Kuj paub, zinc puas yog ib qho zoo conductor ntawm tshav kub thiab hluav taws xob?

Hauv chav sov, zinc yog nkig, tab sis nws dhau los ua malleable ntawm 100 C. Malleable txhais tau tias nws tuaj yeem khoov thiab zoo li yam tsis muaj kev tawg. Zinc yog ib nrab tus neeg xyuas pib zoo ntawm hluav taws xob . Lub cev siv zinc ua cov khoom noj thiab cov khoom noj.

Puas yog kev hloov pauv hlau zoo conductors ntawm tshav kub thiab hluav taws xob?

Hloov cov hlau yog superior conductors ntawm tshav kub zoo li hluav taws xob . Lawv yog cov malleable, uas txhais tau hais tias lawv tuaj yeem ua rau hauv cov nplooj ntawv, thiab ductile, uas txhais tau tias lawv tuaj yeem ua rau hauv cov xov hlau. Qee cov khoom ntawm kev hloov hlau muab lawv sib nrug ntawm lwm tus hlau.
