Kev siv Niobium

Nws tau tshawb pom ib lub sijhawm ntev dhau los uas thaum qhov kub thiab txias tau qis dua rau ze li xoom, cov khoom siv tshuaj lom neeg ntawm qee yam khoom tam sim ntawd hloov pauv thiab lawv dhau los ua "superconductors" uas yuav luag tsis muaj kev tiv thaiv. Qhov kub ntawm cov khoom pib muaj qhov txawv txav "superconducting" cov cuab yeej hu ua qhov ntsuas kub tseem ceeb. Needless hais, qhov kub tseem ceeb ntawm ntau yam khoom sib txawv.

Nws yog ib qho tseem ceeb kom paub tias qhov kub thiab txias tsis yog ib qho yooj yim kom tau, thiab tib neeg them tus nqi loj rau lawv; qhov zero peb tau mus rau qhov zero, qhov ntau dua tus nqi peb yuav tsum tau them. Yog li peb qhov kev xav tau rau cov khoom siv superconducting yog, ntawm chav kawm, qhov siab dua qhov kub thiab txias, qhov zoo dua.

Muaj ntau lub ntsiab lus nrog superconducting zog, thiab niobium muaj ib qho ntawm qhov kub siab tshaj plaws. Cov alloy ua los ntawm niobium muaj qhov kub thiab txias siab txog 18.5 txog 21 degrees qhov kub thiab txias, uas yog cov khoom tseem ceeb tshaj plaws nyob rau tam sim no.
