Cov pa roj tsawg(tseem hu ua cov pa roj inert), suav nroghelium (He), neon (Ne), argon (Ar),krypton (Kr), xenon (Xe), siv dav hauv ntau qhov chaw vim lawv cov khoom siv tshuaj lom neeg ruaj khov heev, tsis muaj xim thiab tsis muaj ntxhiab, thiab nyuaj rau teb. Cov hauv qab no yog kev faib tawm ntawm lawv cov kev siv tseem ceeb:

Cov pa roj tiv thaiv: siv nws cov tshuaj lom neeg tsis muaj zog los tiv thaiv kev oxidation lossis kev ua qias tuaj

Kev Vuam thiab Kev Lag Luam Hlau: Argon (Ar) yog siv rau hauv cov txheej txheem vuam los tiv thaiv cov hlau reactive xws li txhuas thiab magnesium; hauv kev tsim khoom semiconductor, argon tiv thaiv silicon wafers los ntawm kev ua qias tuaj los ntawm cov khoom tsis huv.

Kev ua haujlwm kom raug: Cov roj nuclear hauv cov reactors atomic raug ua tiav hauv ib puag ncig argon kom tsis txhob oxidation. Ntev lub neej ua haujlwm ntawm cov khoom siv: Kev sau nrog argon lossis krypton roj ua rau qeeb qeeb ntawm cov hlau tungsten evaporation thiab txhim kho kev ruaj khov.

Teeb pom kev zoo thiab cov khoom siv hluav taws xob

Teeb neon thiab teeb qhia: Teeb neon thiab teeb qhia: Teeb neon: (Ne) teeb liab, siv rau hauv tshav dav hlau thiab cov paib tshaj tawm; roj argon tso tawm lub teeb xiav, thiab helium tso tawm lub teeb liab.

Kev teeb pom kev zoo heev:Xenon (Xe)siv rau hauv lub tsheb teeb thiab teeb pom kev zoo rau nws qhov ci ntsa iab thiab lub neej ntev;kryptonsiv rau hauv cov teeb pom kev zoo uas txuag hluav taws xob. Kev siv tshuab laser: Helium-neon lasers (He-Ne) siv rau hauv kev tshawb fawb, kev kho mob, thiab kev luam theej barcode.

Cov ntawv thov rau lub npas, lub dav hlau thiab kev dhia dej

Helium qhov ceev tsawg thiab kev nyab xeeb yog cov yam tseem ceeb.

Kev hloov pauv hydrogen:Heliumyog siv los sau cov npas thiab cov dav hlau, tshem tawm cov kev pheej hmoo ntawm kev kub hnyiab.

Kev dhia dej tob hauv hiav txwv: Heliox hloov nitrogen kom tiv thaiv kev qaug zog nitrogen thiab kev lom oxygen thaum dhia dej tob (qis dua 55 meters).

Kev kho mob thiab kev tshawb fawb txog kev tshawb fawb

Kev Thaij Duab Kho Mob: Helium yog siv los ua cov dej txias hauv MRIs kom cov hlau nplaum superconducting txias.

Kev Siv Tshuaj loog thiab Kev Kho Mob:Xenon, nrog nws cov khoom siv tshuaj loog, yog siv rau hauv kev phais mob tshuaj loog thiab kev tshawb fawb txog kev tiv thaiv hlwb; radon (radioactive) yog siv rau hauv kev kho mob qog noj ntshav.

Cryogenics: Cov kua helium (-269 ° C) yog siv rau hauv qhov chaw kub qis heev, xws li kev sim superconducting thiab cov khoom siv accelerators.

Cov thev naus laus zis siab thiab cov teb tshiab

Kev Tsav Tsheb Mus Rau Qhov Chaw: Helium yog siv rau hauv cov tshuab roj foob pob hluav taws.

Lub Zog Tshiab thiab Cov Khoom Siv: Argon siv rau hauv kev tsim cov roj teeb hnub ci los tiv thaiv qhov huv ntawm silicon wafers; krypton thiab xenon siv rau hauv kev tshawb fawb thiab kev txhim kho roj teeb.

Ib puag ncig thiab Geology: Argon thiab xenon isotopes yog siv los taug qab cov chaw ua pa phem hauv huab cua thiab txiav txim siab txog hnub nyoog geological.

Cov kev txwv ntawm cov peev txheej: Helium tsis rov ua dua tshiab, ua rau kev siv tshuab rov ua dua tshiab tseem ceeb zuj zus.

Cov pa roj tsawg, nrog lawv qhov ruaj khov, ci ntsa iab, qis qhov ceev, thiab cov khoom cryogenic, permeate kev lag luam, tshuaj, aerospace, thiab lub neej txhua hnub. Nrog rau kev nce qib ntawm thev naus laus zis (xws li kev tsim cov tshuaj helium siab), lawv cov ntawv thov txuas ntxiv nthuav dav, ua rau lawv yog qhov tseem ceeb "tsis pom kev" ntawm thev naus laus zis niaj hnub.
