Superfluids tuaj yeem siv hauv gyroscopes, los pab cov cav tov kwv yees cov ntaub ntawv hais txog lub ntiajteb txawj nqus txav uas tsis tuaj yeem nqa nrog cov twj paj nruag ib txwm muaj.
Koj pom cov dej nyob qhov twg?
Superfluidity tshwm sim nyob rau hauv ob isotopes ntawm helium (helium-3 thiab helium-4) thaum lawv liquefied los ntawm txias rau cryogenic kubNws kuj yog ib yam khoom ntawm ntau lwm yam kab txawv xeev. ntawm qhov teeb meem theorized kom muaj nyob rau hauv astrophysics, high-zog physics, thiab theories ntawm quantum gravity.
piv txwv ntawm ib qho superfluid yog dab tsi?
Piv txwv ntawm superfluids suav nrog helium-3 (los yog ³He) thiab helium-4 (los yog ⁴He) Rau qhov kub qis dua 2.17 K, helium-4 dhau los ua superfluid. Helium-3 dhau los ua ib qho superfluid qis dua 0.0025 K. Tsis tas li ntawd, thaum cov superfluids tau nplawm, lawv tsim cov vortices uas "rotate indefinitely" (saib daim duab.
Dab tsi yog qhov teeb meem superfluid?
: qhov txawv txav ntawm qhov teeb meem tau sau tseg tsuas yog hauv cov kua helium txias kom ze rau qhov tsis muaj tseeb thiab tus yam ntxwv los ntawm qhov tsis muaj kev sib txhuam (xws li los ntawm cov qhov zoo)
YPuas yog helium Tsuas yog superfluid?
Yog, para hydrogen, hauv qhov txwv. Kev ua haujlwm tsis ntev los no ntawm Göttingen tau nthuav tawm cov pov thawj ntseeg siab rau cov kua dej hydrogen, tsuas yog kua lwm yam tsis yog heliumlos nthuav tawm qhov kev coj cwj pwm no.

Dab tsi yog qhov txawv ntawm qhov tsis siv neeg thiab 6 ceev tsis siv neeg?
Ib txwm tsis siv neeg muaj qhov kawg ntawm lub zog uas raug xa mus rau qhov nrawm. Piv txwv li, tej zaum koj yuav tau hnov lo lus 6-ceev tsis siv neeg. Qhov no yog hais txog rau lub zog hauv kev sib kis. … Tsis zoo li cov kis tsis siv neeg zoo tib yam, tsav tsheb yuav tsis hnov qhov kev hloov ntawm ib lub iav mus rau lwm qhov Dab tsi yog qhov txawv ntawm 6-ceev tsis siv neeg thiab 10 ceev tsis siv neeg?
Puas yog helium tsuas yog superfluid?
Kev ua haujlwm tsis ntev los no ntawm Göttingen tau nthuav tawm cov pov thawj ntseeg siab rau cov dej hauv cov kua hydrogen, tsuas yog kua lwm yam tsis yog helium los nthuav tawm qhov kev coj cwj pwm no . Yuav ua li cas yog dej super?
Qhov twg yog qhov mob thiab qhov twg yog qhov ceeb?
Panic (lub suab los ntawm Matt Frewer) yog lub ntsej muag ntsuab-xiav nrog lub cev ntev. Thaum nws yog me ntsis cunning dua Pain, nws paranoia txhais tau hais tias nws yog heev ceev faj thiab ntau cynical nyob rau hauv lub sij hawm, yog li nws tej zaum yuav ntse dua ib tug ntawm ob.
Qhov twg yog qhov siv rau qhov luam tawm lossis tsis tau tshaj tawm?
A citation yog ib qho ntaub ntawv siv rau ib qho kev luam tawm lossis tsis tau tshaj tawm qhov chaw uas koj tau sab laj thiab tau txais cov ntaub ntawv los ntawm thaum sau koj cov ntawv tshawb fawb . Yuav ua li cas hais txog qhov tsis tau tshaj tawm?
Qhov kev txiav txim siab siv tau siv qhov twg?
Kev txiav txim siab thiab kev txiav txim siab tuaj yeem ua tau zoo heev rau cov koom haum thiab tseem muaj txiaj ntsig rau cov tib neeg hauv ntau txoj haujlwm, suav nrog kev noj qab haus huv, kev kawm, kev pabcuam nyiaj txiag thiab kev lag luam .
