Kub nws tus kheej tsis dhau los ua tus superconductor - saum toj ntawm millidegree ntau txawm tias nws yog qhov ntshiab heev, txawm tias tsis muaj cov kev daws teeb meem kub-nplua nuj txog tam sim no kawm tau ua pov thawj tias yog superconducting. Hauv kev tsim cov kev daws teeb meem nrog lawv feem ntau, kub txo qis T.
Puas yog nyiaj yog superconductor?
Txhais tau tias, qhov zoo tshaj plaws conductors ntawm chav tsev kub (kub, nyiaj, thiab tooj liab) tsis txhob ua superconducting txhua. Lawv muaj qhov me me ntawm txoj hlua khi, yog li lawv tus cwj pwm sib raug zoo nrog BCS Txoj Cai.
Yuav ua li cas cov hlau qhia superconductors?
Qee yam tseem ceeb ntawm cov khoom tseem ceeb yog- Aluminium, Zinc, Cadmium, Mercury, thiab Lead . Hom superconducting compounds thiab alloys yog- PbAu, PbTl 2, SnSb, CuS, NbN, NbB thiab NrC.
Vim li cas kub thiab nyiaj tsis yog superconductors?
tooj liab thiab kub muajntau dhau ntawm cov khoom siv hluav taws xob tsis zoo thiab cov khoom loj dhau hauv lub xeev ib txwm Qhov nce hauv lub zog dawb los ntawm superconducting electrons tsis tuaj yeem them nyiaj antigain los ntawm nonsuperconducting electrons thiab antigain ntawm electron conductivity (hall tas li <0).
Ib co piv txwv ntawm superconductors yog dab tsi?
Cov piv txwv tseem ceeb ntawm superconductors suav nrog aluminium, niobium, magnesium diboride, khob xws li yttrium barium tooj liab oxide thiab hlau pnictides. Cov ntaub ntawv no tsuas yog ua superconducting ntawm qhov kub thiab txias qis dua ib qho nqi, hu ua qhov kub thiab txias.
