Cov khoom no yog dab tsi?
Neon yog cov roj uas tsis muaj roj, thiab tsis muaj xim, tsis muaj ntxhiab thiab tsis qab. Nws yog qhov thib ob lightest noble roj tom qab helium thiab muaj qis boiling thiab melting point. Neon muaj qhov cuam tshuam tsis tshua muaj zog thiab tsis yooj yim tsim cov tebchaw ruaj khov, ua rau nws yog ib qho ntawm cov ntsiab lus tsis zoo tshaj plaws. Neon roj kuj tsis tshua muaj nyob hauv ntiaj teb. Nyob rau hauv cov huab cua, neon tsuas yog ib feem me me (kwv yees li 0.0018%) thiab tau txais los ntawm fractional distillation ntawm kua cua. Nws kuj tseem pom muaj nyob hauv cov lej hauv cov zaub mov thiab qee cov nkev reservoirs.
Qhov twg siv cov khoom no?
Neon cov paib thiab kev tshaj tawm: cov pa roj neon yog siv rau hauv cov paib neon los tsim cov yeeb yam zoo nkauj thiab qhov muag pom. Cov yam ntxwv liab-txiv kab ntxwv ci ntawm neon yog nrov hauv khw muag khoom, cov ntawv tshaj tawm, thiab lwm yam kev tshaj tawm.
Kho kom zoo nkauj teeb pom kev zoo: Neon kuj yog siv rau cov teeb pom kev zoo nkauj. Neon teeb pom kev tuaj yeem pom hauv cov tuav, hmo ntuj, tsev noj mov, thiab txawm tias yog cov khoom siv hauv tsev. Lawv tuaj yeem ua rau ntau yam qauv tsim thiab xim, ntxiv qhov tshwj xeeb thiab zoo nkauj retro.
Cathode-ray tubes: Neon gas yog siv nyob rau hauv cathode-ray raj (CRTs), uas yog ib zaug siv dav hauv TV thiab computer saib. Cov hlab no tsim cov duab los ntawm kev zoo siab neon roj atoms, ua rau cov xim pixels ntawm qhov screen.
High-voltage indicators: Neon qij feem ntau yog siv los ua cov ntsuas hluav taws xob hauv cov khoom siv hluav taws xob. Lawv ci thaum raug hluav taws xob siab, muab qhov pom kev pom ntawm cov hluav taws xob nyob.
Cryogenics: Txawm tias tsis zoo li, neon yog siv rau hauv cryogenics kom ua tiav qhov kub thiab txias. Nws tuaj yeem siv los ua cov tub yees cryogenic lossis hauv kev sim cryogenic uas yuav tsum tau txias txias heev.
Laser technology: Neon gas lasers, hu ua helium-neon (HeNe) lasers, yog siv nyob rau hauv scientific thiab industrial daim ntaub ntawv. Cov lasers no tso tawm lub teeb liab pom thiab muaj kev siv hauv kev sib dhos, spectroscopy, thiab kev kawm.
Nco ntsoov tias cov ntawv thov tshwj xeeb thiab cov cai rau kev siv cov khoom siv / cov khoom no yuav txawv ntawm lub teb chaws, kev lag luam thiab lub hom phiaj. Nco ntsoov ua raws li cov lus qhia kev nyab xeeb thiab sab laj nrog tus kws tshaj lij ua ntej siv cov khoom siv / cov khoom no hauv txhua daim ntawv thov.
