Ntiaj teb no helium tsis txaus cuam tshuam rau kev lag luam khoom siv kho mob

Qhov tsis txaus ntawm helium tsis tu ncua tau cuam tshuam rau ntau yam kev lag luam hauv xyoo tas los no. Ib qho ntawm cov kev lag luam tshwj xeeb cuam tshuam los ntawm helium tsis txaus yog kev lag luam khoom siv kho mob, vim tias cov peev txheej no ua lub luag haujlwm tseem ceeb hauv nws txoj haujlwm thiab kev txhim kho.

Helium yog qhov tseem ceeb rau ntau yam ntawm lub neej niaj hnub, los ntawm tog balloons mus rau magnetic resonance imaging (MRI) tshuab. Tshwj xeeb, nws ua lub luag haujlwm tseem ceeb hauv kev lag luam khoom siv kho mob, muab cov dej txias rau cov lasers siv hauv kev phais, lossis muab tso rau hauv lwm hom khoom siv los kuaj lossis saib xyuas cov neeg mob. Yog li ntawd, ib qho kev cuam tshuam ntawm kev xa khoom tuaj yeem ua rau qeeb thiab ua rau cov nqi nce ntxiv nrog rau kev tsim khoom ntawm cov khoom no. Yog tias tsis muaj kev nkag mus rau cov roj tsawg txaus, cov tuam txhab tsim khoom tsis tuaj yeem tsim cov khoom zoo rau cov tsev kho mob thiab cov kws kho mob. Kev xa khoom tau nce zuj zus vim qhov kev thov nce ntxiv vim muaj kev sib kis tsis tu ncua. Qhov tsis muaj qhov no ua rau cov nqi ntau dua thiab qeeb hauv kev tsim khoom thiab xa khoom. Yog tsis muaj kev nkag tau mus rau qhov pheej yig thiab txhim khu kev qha ntawm helium, tuam txhab lag luam tawm tsam kom tau raws li cov neeg siv khoom xav tau thaum tseem muaj txiaj ntsig. Cov teeb meem no tuaj yeem cuam tshuam cov neeg mob kuaj mob thiab kho, ua rau cov txiaj ntsig tsis zoo thiab kev tuag ntau dua.

Txhawm rau ua kom tau raws li cov kev cov nyom no, tsoomfwv yuav tsum ua qhov tseem ceeb hauv kev nqis peev tshiab ntawm cov khoom siv helium, xws li cov khoom siv hluav taws xob los yog cov chaw sib cais huab cua, kom ntseeg tau tias muaj txaus rau kev lag luam khoom siv kho mob. Tsis tas li ntawd, kev tshawb fawb ntxiv yuav tsum tau ua ntawm lwm cov ntaub ntawv uas tuaj yeem hloov helium hauv qee qhov kev siv, yog li muab cov neeg tsim khoom xaiv ntau dua thaum muab cov khoom sib xyaw.

Txhawm rau daws cov teeb meem no, ntau lub tuam txhab kho mob tau hloov mus rau lwm cov pa roj xws li nitrogen lossis argon uas tuaj yeem hloov helium hauv qee daim ntawv thov. Txawm hais tias qhov no tsis tuaj yeem cuam tshuam tag nrho cov kev poob uas cuam tshuam nrog kev nce nqi thiab kev cuam tshuam qeeb, nws muab cov kev daws teeb meem luv luv kom txog thaum cov peev txheej tshiab ntawm helium dhau los lossis cov peev txheej uas twb muaj lawm nce txaus kom tau raws li qhov xav tau ntxiv. Ua cov kauj ruam tam sim no tuaj yeem pab ua kom muaj kev nyab xeeb yav tom ntej rau peb cov kab ke kev noj qab haus huv thiab cov neeg vam khom.
