Niobium superconductivity
Feb 27, 2024
Nws tau tshawb pom ntev dhau los tias thaum qhov kub thiab txias tau qis dua rau ze li xoom, cov khoom siv tshuaj lom neeg ntawm qee yam tshuaj hloov pauv sai sai 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. Thiab niobium alloy, qhov ntsuas kub tseem ceeb txog qhov ntsuas kub ntawm 18.5 txog 21 degrees, tam sim no yog cov khoom siv tseem ceeb tshaj plaws.
Tib neeg ib zaug tau ua qhov kev sim no: txias rau lub xeev superconducting ntawm lub nplhaib hlau niobium, hla qhov tam sim no thiab tom qab ntawd txiav tawm tam sim no, thiab tom qab ntawd, tag nrho cov cuab yeej kaw tau kaw, kom tsis txhob kub. Tom qab ob xyoos thiab ib nrab xyoo, tib neeg qhib lub cuab yeej, pom tias lub nplhaib niobium nyob rau hauv tam sim no tseem ntws, thiab tam sim no lub zog thiab tsuas yog energized yuav luag ib yam nkaus!



Los ntawm qhov kev sim no, nws tau pom tseeb tias cov khoom siv superconducting poob yuav luag tsis muaj tam sim no. Yog tias cov kab hluav taws xob superconducting siv rau kev xa hluav taws xob, kev ua haujlwm ntawm lub zog xa hluav taws xob yuav zoo dua vim nws tsis muaj kev tiv thaiv thiab yuav tsis muaj zog poob thaum tam sim no dhau mus.
Ib tug neeg tau tsim ib lub tsheb ciav hlau ceev ceev sib nqus uas muaj cov hlau nplaum superconducting ntsia rau hauv lub log qhov chaw kom tag nrho lub tsheb ciav hlau tuaj yeem ntab ntawm txoj kev mus txog kaum centimeters. Nyob rau hauv txoj kev no, yuav tsis muaj kev sib txhuam ntxiv ntawm lub tsheb ciav hlau thiab txoj kev khiav, txo qhov tsis kam mus rau kev vam meej. Lub tsheb ciav hlau maglev nrog cov neeg caij tsheb muaj peev xwm ntawm ib puas tuaj yeem ncav cuag ntau tshaj tsib puas kilometers ib teev nrog tsuas yog ib puas horsepower ntawm propulsion.
Nrog rau txoj siv niobium-tin nees nkaum kilometers ntev, qhwv ib ncig ntawm lub log nrog ib txoj kab uas hla ntawm ib thiab ib nrab meters, lub windings muaj peev xwm tsim ib tug muaj zog thiab ruaj khov magnetic teb muaj zog txaus nqa ib tug luj ntawm ib puas thiab nees nkaum. -ob kilograms thiab ua rau nws levitate nyob rau hauv lub magnetic teb chaw. Yog tias qhov chaw sib nqus no tau siv rau hauv cov tshuaj tiv thaiv thermonuclear fusion kom coj cov tshuaj tiv thaiv thermonuclear fusion muaj zog nyob rau hauv kev tswj hwm, nws yuav muaj peev xwm muab peb cov hluav taws xob loj uas yuav luag tsis muaj qhov kawg.
Tib neeg tau ua lub tshuab hluav taws xob DC tawm ntawm niobium-titanium superconducting khoom. Nws muaj ntau yam zoo, xws li qhov me me, lub teeb yuag, tus nqi qis, thiab nws tsim hluav taws xob ntau pua npaug piv rau lub tshuab hluav taws xob zoo tib yam ntawm tib qhov loj.
