Dab tsi yog Scope ntawm Kev Siv Helium?
Dec 12, 2022
Helium yog cov khoom lag luam uas muaj ntau yam kev siv, tab sis cov roj no yog cov khoom siv tsawg heev hauv Suav teb, yog li tus nqi feem ntau siab. Cia peb qhia txog daim ntawv thov ntau yam ntawm cov khoom no hauv kev nthuav dav hauv qab no.
Helium kuj tseem siv tau los ua cov roj tiv thaiv hauv atomic reactors thiab accelerators, lasers, foob pob ua ntxaij, smelting thiab vuam, nws kuj tseem siv tau los sau cov qij thiab cov raj neon, thiab nws kuj yog siv los ua npuas yas.
Vim qhov tsis tshua muaj solubility ntawm helium hauv cov ntshav, nws tuaj yeem muab ntxiv rau oxygen raws li tus neeg dhia dej ua pa. Nws puas txaus ntshai rau helium? Helium yog siv rau cov pa roj hauv hiav txwv tob, nws tuaj yeem pom tias helium tsis txaus ntshai!
Qhov kub ntawm cov kua helium yog ze rau qhov xoom (-273 degree), yog li nws yog siv los ua ib qho superfluid hauv kev tshawb fawb superconductivity los ua cov khoom siv superconducting. Liquid helium kuj yog siv los ua ib qho coolant thiab refrigerant.
Hauv tshuaj, helium yog siv hauv argon-helium riam los kho mob qog noj ntshav.
Helium kuj tseem siv los ua ib feem ntawm cov khoom cua cua thiab laser media.
Helium tuaj yeem siv los khaws cov neeg tuag, thiab cov roj hauv Mao Zedong lub hleb siv lead ua yog helium.
