A fermionic condensate lossis Fermi-Dirac condensate yog superfluid superfluid Cov khoom siv superfluid muaj xoom viscosity thiab xoom entropy. Kev siv cov cua sov rau ib qho chaw hauv superfluid helium ua rau muaj qhov ntws ntawm cov khoom siv ib txwm siv uas saib xyuas cov cua sov thauj ntawm qhov nrawm nrawm (txog 20 cm / s) uas ua rau muaj txiaj ntsig zoo thermal conductivity.. https://en.wikipedia.org › wiki › Superfluid_helium-4

theem tsim los ntawm cov khoom fermionic ntawm qhov kub thiab txias. Nws muaj feem cuam tshuam nrog Bose-Einstein condensate, theem superfluid tsim los ntawm bosonic atoms nyob rau hauv cov xwm txheej zoo sib xws.
Yuav ua li cas thiaj tsim tau Bose-Einstein condensate?
Ua kom Bose-Einstein condensate, koj pib nrog huab cua diffuse. Ntau qhov kev sim pib nrog atoms ntawm rubidium. Tom qab ntawd koj txias nws nrog lasers, siv cov kab teeb kom coj lub zog tawm ntawm cov atoms. Tom qab ntawd, kom txias lawv ntxiv, cov kws tshawb fawb siv evaporative txias.
Leej twg tsim fermionic condensate?
Vim li no, peb xav tsis thoob thiab zoo siab tau kawm tias Deborah Jin, Cindy Regal thiab Markus Greiner ntawm JILA lub chaw kuaj mobhauv Asmeskas tau tsim thawj fermionic condensate los ntawm kev ua kom txias. ib tug roj ntawm poov tshuaj atoms rau nanokelvin kub (Phys. Rev. Lett. 92 040403).
Dab tsi yog qhov txawv ntawm Bose-Einstein Condensate thiab fermioniccondensate?
A fermionic condensate, lossis fermi condensate, yog lub xeev teeb meem (superfluid theem) uas zoo ib yam li Bose-Einstein condensate. … Qhov txawv tsuas yog uas Bose-Einstein condensates yog tsim los ntawm bosons, thiab muaj kev sib raug zoo nrog ib leeg (hauv pab pawg, lossis pawg).
Thaum twg yog fermionic condensate tsim?
"Lub sijhawm no yog lub sijhawm zoo siab heev," hais tias University of Colorado / NIST physicist Deborah Jin, tus thawj coj kws tshawb fawb rau pab pawg uas tsim thawj fermionic condensate hauv Kaum Ob Hlis. 2003.

Yuav ua li cas sau ntawv thiab yuav ua li cas?
Tab sis tiag tiag, sau ntawv tsuas yog txhais tau tias tso tseg me ntsis nyob ntsiag to, tsis muaj sijhawm los zaum thiab xav txog koj lub neej. Nws tuaj yeem yog los ntawm kev sau cov ntaub ntawv ntawm qhov koj tau ua hnub ntawd; los ntawm venting txog ib yam uas koj tsis tuaj yeem tawm ntawm koj lub siab;
Yuav ua li cas rau ib tug neeg txhais li cas?
verb (siv nrog khoom), mi·icked, mi·ick·ing. muab los yog luam tawm hauv kev ua, hais lus, thiab lwm yam., feem ntau playfully los yog derisively. coj raws li kev ua haujlwm tsis zoo lossis tsis xav txog; ape. ua ib tug imitation ntawm; simulate;
Puas yog cov dej condensate?
Koj lub tshuab cua txias muaj cov kab dej condensate uas khiav ntawm chav tsev sab hauv mus rau sab nraud ntawm koj lub tsev. Koj yuav pom cov yeeb nkab PVC dawb lossis tooj liab nyob ze ntawm koj lub tsev sab nraum zoov-qhov no yog qhov kawg ntawm txoj kab dej.
Puas yog condensate neutralizers xav tau?
Yog, txawm tias koj tsis tas yuav siv ib qho . Hom condensate los ntawm condensing boiler condensing boiler Condensing boilers yog dej rhaub los ntawm roj los yog roj. Lawv ua tiav kev ua haujlwm siab (feem ntau ntau dua 90% ntawm cov nqi cua sov siab dua) los ntawm kev ua kom cov dej vapor hauv cov pa tso pa tawm thiab ua kom rov qab tau nws cov cua sov latent ntawm vaporisation, uas yuav txwv tsis pub nkim.
Cov yeeb nkab condensate nyob qhov twg ntawm boiler?
Saib hauv qab lub boiler kom pom tias muaj cov yeeb nkab yas - Nws feem ntau yog dawb thiab nyob ib ncig ntawm 20mm (txog ¾ ") dav. Cov yeeb nkab yuav tsum khiav mus rau sab nraud ntawm koj lub tsev thiab yuav tsum khiav mus rau hauv qhov dej ntws.
