Tsis muaj cov tshuab ua kuahydrogenthiab kuahelium, qee qhov chaw tshawb fawb loj yuav yog pawg ntawm cov khoom siv hlau... Cov kua hydrogen thiab kua helium tseem ceeb npaum li cas?
Cov kws tshawb fawb Suav tau kov yeej li cashydrogenthiab helium uas tsis tuaj yeem ua liquefy? Txawm nyob rau hauv qeb ntawm qhov zoo tshaj plaws nyob rau hauv lub ntiaj teb no? Cia peb nthuav tawm cov ntsiab lus kub xws li "Ice Arrow" thiab helium to, thiab taug kev mus rau tshooj zoo kawg nkaus ntawm kuv lub teb chaws kev lag luam cryogenic ua ke.
Ice Rocket: Qhov Miracle ntawm Kua Hydrogen thiab kua Oxygen
Peb Tuam Tshoj Lub Peb Hlis 5 lub foob pob hluav taws ntev, "Hercules" ntawm kev lag luam aerospace, "90% ntawm cov roj yog kuahydrogenntawm rho tawm 253 degrees Celsius thiab kua oxygen ntawm rho tawm 183 degrees Celsius” - qhov no yog ze rau qhov txwv ntawm qhov kub thiab txias, thiab nws kuj yog lub hauv paus chiv keeb ntawm lub npe “Ice Rocket”.
Vim li cas ho xaiv cov kua hydrogen?
Qhov laj thawj yog yooj yim: tib pawg ntawmhydrogenmuaj qhov ntim ntawm li 800 npaug ntawm cov kua hydrogen. Siv cov roj ua kua, lub foob pob hluav taws "roj tank" txuag tau ntau qhov chaw, thiab lub plhaub tuaj yeem ua kom nyias, thiaj li nqa tau ntau dua rau saum ntuj. Kev sib xyaw ua ke ntawm cov kua hydrogen thiab kua oxygen tsis yog tsuas yog ib puag ncig tus phooj ywg xwb, tab sis kuj tuaj yeem tsim kom muaj kev nce nrawm dua thiab txhim kho lub tshuab ua haujlwm. Nws yog qhov kev xaiv zoo tshaj plaws rau lub foob pob hluav taws.
Helium leak: Tus neeg tua neeg tsis pom nyob hauv thaj chaw aerospace
SpaceX yog thawj zaug tau teem sijhawm los ua lub luag haujlwm "North Star Dawn" thaum kawg ntawm Lub Yim Hli, tab sis kev tshaj tawm tau raug ncua vim qhov kev tshawb pom ntawmheliumxau ua ntej tso tawm. Helium plays lub luag haujlwm ntawm "muab koj txhais tes" ntawm lub foob pob hluav taws. Nws tso kua oxygen rau hauv lub cav zoo li lub koob txhaj tshuaj.
Txawm li cas los xij,heliummuaj qhov hnyav molecular me me thiab yooj yim heev rau xau, uas yog qhov txaus ntshai heev rau qhov chaw siv tshuab. Qhov xwm txheej no ib zaug ntxiv qhia txog qhov tseem ceeb ntawm helium hauv thaj chaw aerospace thiab qhov nyuaj ntawm nws daim ntawv thov.
Hydrogen thiab helium: cov ntsiab lus ntau tshaj plaws hauv lub ntiaj teb
Hydrogen thiabheliumTsis tsuas yog "cov neeg nyob ze" nyob rau hauv lub sij hawm lub sij hawm, tab sis kuj yog lub feem ntau abundance ntawm lub ntug. Hydrogen fusion tso tawm cua sov los ua helium, ib qho tshwm sim uas tshwm sim txhua hnub ntawm lub hnub.
Lub liquefaction ntawmhydrogenthiab helium siv tib txoj kev tub yees, thiab lawv cov liquefaction kub tsis tshua muaj siab, ntawm -253 ℃ thiab -269 ℃ feem. Thaum qhov kub ntawm cov kua helium poob rau -271 ℃, kev hloov pauv superfluid kuj yuav tshwm sim, uas yog cov nyhuv macroscopic quantum.
Kev txhim kho ntawm cov thev naus laus zis xws li quantum suav yuav muaj qhov xav tau ntau ntxiv rau qhov chaw kub tsis tshua muaj siab, thiab cov kws tshawb fawb Suav yuav txuas ntxiv mus ua ntej ntawm kev mus rau qhov kub thiab txias thiab pab txhawb ntau ntxiv rau kev tshawb fawb thiab thev naus laus zis. Ua tsaug rau cov kws tshawb fawb, thiab cia peb tos ntsoov rau lawv txoj kev vam meej yav tom ntej!
