Cambridge cov kws tshawb fawb tau txheeb xyuas cov khoom siv uas coj tus cwj pwmthiab ib qho hluav taws xob. Cov khoom siv, samarium hexaboride (SmB6), ua zoo li lub rwb thaiv tsev hauv qee qhov kev ntsuas, tab sis ib txhij ua zoo li tus neeg xyuas pib hauv lwm tus.
Txhua yam khoom puas tuaj yeem ua tus coj?
Txhua cov hlau yog cov khoom siv hluav taws xob. Dynamic hluav taws xob, los yog hluav taws xob tam sim no, yog ib qho kev txav ntawm electrons los ntawm tus neeg xyuas pib. Cov hluav taws xob zoo li qub yog qhov tsis txav mus los, cov nqi tsim los ntawm ib qho dhau los lossis tsis txaus ntawm cov khoom siv hluav taws xob hauv ib yam khoom.
Yuav siv cov khoom siv li cas?
Ntau cov ntaub ntawv siv los xa hluav taws xob, tab sis cov feem ntau tau teev tseg rau hom conductors yogtooj liab, tooj liab npog hlau, siab zog tooj liab alloys, thiab txhuas.
Cov khoom siv twg tuaj yeem siv los ua tus neeg xyuas pib thiab lub rwb thaiv tsev?
Review
- Cov khoom siv hluav taws xob tau yooj yim heev vim lawv cov hluav taws xob dawb.
- Insulators tawm tsam hluav taws xob tam sim no thiab ua rau cov neeg ua haujlwm tsis zoo.
- Qee yam khoom siv yog tooj liab, txhuas, kub, thiab nyiaj.
- Qee yam insulators yog iav, cua, yas, roj hmab, thiab ntoo.
Puas yog txhua yam khoom yog tus neeg xyuas pib zoo lossis insulator?
Hlau feem ntau yog cov conductors zoo heev, txhais tau tias lawv cia tam sim no ntws yooj yim. Cov ntaub ntawv uas tsis txhob cia tam sim no ntws yooj yim yog hu ua insulators. Feem ntau cov ntaub ntawv tsis yog hlau xws li yas, ntoo thiab roj hmab yog insulators.
