Helium Balloon Inflation
Feem ntau siv rau helium tso tsheb hlau luam yog inflating helium balloons, tshwj xeeb tshaj yog rau cov sij hawm xws li cov me nyuam hnub yug thiab cov kev ua koob tsheej. Tsis zoo li cov huab cua zoo tib yam, helium tso cai rau cov balloons ntab; Tsis tas li ntawd, lub suab tsim los ntawm helium balloons txawv ntawm cov qauv balloons, muaj qhov sib dua thiab zoo nkauj dua. Tsis tas li ntawd, helium balloons nquag siv rau kev tshaj tawm kev tshaj tawm thiab cov hom phiaj zoo sib xws.
Kev sim kev tshawb fawb
Helium ua haujlwm tseem ceeb hauv kev sim roj nrog kev siv dav hauv ntau qhov chaw, suav nrog physics, chemistry, thiab astronomy. Piv txwv li, helium tuaj yeem ua haujlwm los tiv thaiv cov khoom siv thaum lub sijhawm sim, tiv thaiv kev sib kis lossis oxidation. Ntxiv mus, helium ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov cuab yeej xws li Sib Nqus Resonance Imaging (MRI) scanners thiab helium-neon lasers.
Khoom siv kho mob
Helium kuj pom muaj ntau daim ntawv thov hauv kev kho mob, tshwj xeeb hauv kev kho ua pa. Thaum kho ua pa- tswj hwm los ntawm helium tso tsheb hlau luam- cov pa roj ua haujlwm los ntawm kev txo cov pa tsis haum. Qhov no mechanism ua hauj lwm los txhim kho cov neeg kho tshuab efficiency ntawm kev ua pa thiab pab txhawb kom ceev clearance ntawm hnoos qeev thiab exhaled cua.
Vuam
Helium kuj tseem siv rau hauv cov txheej txheem hlau vuam, tshwj xeeb tshaj yog nyob rau hauv vuam ntawm aluminium alloys. Thaum welding nyob rau hauv ib tug helium shield, aluminium alloy tsis tshua muaj oxidation, uas ua rau superior weld zoo.
