Tomsic piav qhia tias MRIs tam sim no siv niobium titanium superconductors uas tau txias hauv da dej ntawm cov kua heliumCov kua helium pab tiv thaiv cov hlau nplaum quenches qhov twg cov hlau nplaum nce hauv qhov kub vim qhov cua sov hauv zos. thiab tuaj yeem ua rau puas tsuaj. Qee lub tshuab MRI tau ntsib qhov teeb meem ntau dua li lwm tus.
Vim li cas superconducting hlau nplaum siv hauv MRI?
Superconductive MRI cov hlau nplaum siv lub voj voog solenoid ua los ntawm cov hlau xws li niobium / titanium lossis niobium / tin puag ncig ntawm tooj liab. Cov alloys no muaj qhov khoom ntawm xoom tsis kam rau hluav taws xob tam sim no thaum txias rau txog 10 kelvin. Lub kauj yog khaws cia hauv qab no nrog cov kua helium.
Yuav siv cov superconductors li cas?
Cov khoom siv superconducting tau siv sim ua kom nrawm kev sib txuas ntawm lub computer chips, thiab cov coils superconducting ua tau cov hluav taws xob muaj zog heev ntawm kev ua haujlwm hauv qee qhov kev sib nqus resonance imaging (MRI) cov kws kho mob siv cov tshuab los tshuaj xyuas cov ntaub so ntswg hauv lawv cov neeg mob.
Vim li cas feem ntau MRI cov tshuab ua haujlwm zoo tshaj?
MRI feem ntau siv cov hlau nplaum superconducting. Lub ntsiab kom zoo dua yog tias cov hlau nplaum superconducting muaj peev xwm ua kom muaj zog thiab ruaj khov hlau nplaum ntau dua li ob hom (tiv taus thiab ruaj khov) suav nrog hauv qab no.
MRI superconductors yog dab tsi?
Cov khoom siv hluav taws xob ntawm cov hlau nplaum tam sim no feem ntau yog tsim los ntawm niobium-titanium. Cov khoom no muaj qhov kub thiab txias ntawm 10 kelvins thiab muaj peev xwm ua tau superconduct txog li 15 teslas.

Yuav ntim cov khoom siv hauv tsev li cas rau kev mus ncig hauv huab cua?
Feem ntau, cov neeg taug kev tso lawv cov khoom siv tso rau hauv lub hnab xws li tsuaj zawv plaub hau, cov khoom siv plaub hau, pleev thiab tshuaj txhuam hniavCov tib neeg uas xav ntim lawv cov tshuaj zawv plaub hau loj lossis puv puv Cov tshuaj txhuam hniav yuav tsum ntim cov khoom ntawd rau hauv lawv lub hnab kuaj.
Qhov twg yog superconductors tsim?
Cov khoom siv superconductor suav nrog cov khoom siv tshuaj (xws li mercury lossis lead), alloys (xws li niobium-titanium, germanium-niobium, thiab niobium nitride), ceramics (YBCO thiab magnesium diboride), superconducting pnictides (xws li fluorine-doped LaOFeAs) los yog organic superconductors (fullerenes thiab carbon nanotubes;
Vim li cas cov neeg siv khoom thiab cov khoom siv tau siv hauv c ++?
Lub hom phiaj ntawm kev siv getters thiab setters yog txhawm rau zais cov ntaub ntawv khaws cia thiab rov qab li casTxoj kev no, yog tias koj hloov tus cwj pwm, koj tsis tas yuav hloov tus lej. nyob rau hauv ib txhiab qhov chaw. Tab sis, yog tias koj tsis tas yuav hloov qhov kev siv, koj tau ua koj cov cai ntau dua thiab tau txais me ntsis los ntawm kev ua li ntawd .
Yuav ua li cas koj yuav siv insubstantial hauv kab lus?
1. Cov pov thawj zoo li tsis muaj nuj nqis heev. 2. Lub dav hlau thaum ntxov yog cov ntoo thiab cov nplaum tsis muaj nuj nqis . Yuav ua li cas koj siv insubstantial hauv kab lus? Insubstantial nyob rau hauv ib kab lus ? Vim cov pov thawj tsis tseem ceeb, tsis muaj pov thawj txaus los foob tus txiv neej tua neeg.
Yuav ua li cas koj yuav siv connived hauv kab lus?
Lawv tau cog lus thiab txiav txim siab ntawm qhov kev ua txhaum loj tshaj plaws Peb tau txiav txim siab los ntawm kev ua tsis tiav raws sijhawm - qhov kev txiav txim siab yooj yim uas txhua tus neeg uas paub dab tsi txog qhov xwm txheej paub yog kiag li tsim nyog.
