Superconductivity yog qhov tshwm sim ntawm qee cov ntaub ntawv uas qhia txog xoom hluav taws xob tsis kam thiab tshem tawm ntawm cov hlau nplaum hauv qab qhov ntsuas kub. Keeb kwm ntawm superconductivity pib nrog Dutch physicist Heike Kamerlingh Onnes qhov kev tshawb pom ntawm superconductivity hauv mercury hauv 1911.
Thaum twg yog thawj superconductor nrhiav tau?
Ua ntej ntawm tag nrho: Dab tsi yog superconductivity? Nws yog qhov tshwm sim zoo kawg nkaus uas pom nyob rau hauv 1911los ntawm tus tub ntxhais kawm ua haujlwm nrog tus kws tshawb fawb nto moo Dutch, Kamerlingh-Onnes. Kamerlingh-Onnes pioneer ua hauj lwm ntawm qhov kub tsis tshua muaj - kub tsuas yog ob peb degrees saum toj kawg nkaus ntawm qhov kub thiab txias.
Thaum twg yog qhov kub kub superconductor tsim?
thawj lub siab-Tc superconductor tau pom nyob rau hauv 1986 los ntawm IBM cov kws tshawb fawb Georg Bednorz thiab K. Alex Müller, uas tau txais 1987 Nobel nqi zog hauv Physics "rau lawv qhov tseem ceeb so -los ntawm kev tshawb pom ntawm superconductivity hauv cov khoom siv ceramic ".
Kamerlingh Onnes nrhiav tau superconductors li cas?
Thaum cov khoom sib txawv tau txias kom qis qis, lawv cov khoom hloov pauv. … Xyoo 1911 Heike Kamerlingh Onnes nrhiav pom tias qhov hluav taws xob tiv thaiv ntawm mercury tag nrho ploj ntawm qhov kub li ob peb degrees saum toj kawg nkaus xoom Qhov tshwm sim los ua lub npe hu ua superconductivity.
Puas kub yog superconductor?
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.
