Tus resistivity yog cov khoom siv lossis tus neeg xyuas pib yog qhov cuam tshuam lossis tsis kam muab los ntawm nws cov qauv rau cov electrons dawb ntws. … Yog li ntawd, qhov resistivity ntawm alloys yog ntau tshaj nws cov hlau constituent.
Yuav ua li cas tiv thaiv cov alloys piv nrog cov hlau ntshiab?
Cov resistivity ntawm ib qho alloy qis dua cov hlau ntshiab.
Qhov twg muaj ntau dua cov hlau lossis alloy?
dawb electrons tau tawg tawm ntawm qhov tsis zoo thiab alloys muaj ntau ntau dua li cov hlau ntshiab. Qhov kev tiv thaiv siab dua hauv cov alloys piv rau cov khoom sib xyaw yog tshwm sim los ntawm kev sib cais ntxiv ntawm cov electrons hu ua "alloy scattering ".
Kev sib raug zoo ntawm cov hlau tsis muaj zog thiab cov hlau tsis kam yog dab tsi?
Thaum peb ntxiv cov hlau tsis yog hlau, cov qauv siv lead ua hloov pauv uas txo lawv lub peev xwm ua hluav taws xob. Yog li ua kom muaj kev tiv thaiv thiab li no resistivity. Yog li peb tuaj yeem hais tias qhov kev tiv thaiv ntawm cov hlau yog ntau dua qhov kev tiv thaiv ntawm cov hlau.
Vim li cas cov hlau tsis muaj zog dua?
Yog vim li cas - Kev tiv thaiv ntawm ib qho hlau feem ntau siab dua li ntawm nws cov khoom siv hlau tab sis cov alloys muaj cov ntsiab lus melting tsawg dua li lawv cov khoom siv hlau. … Cov yam ntxwv ntawm cov hlau no ua rau kom nce ntxiv resistivity vim dawb crystal lattice.
