He aha kēia mea ?
ʻO ka Helium he kinoea kala ʻole, ʻala ʻole, ʻono ʻole i ʻoi aku ka māmā ma mua o ka ea. Ma kona kūlana kūlohelohe, loaʻa mau ka helium i nā mea liʻiliʻi i ka lewa o ka Honua ma ke ʻano he kinoea. Eia nō naʻe, lawe ʻia ia mai nā pūnāwai kinoea maoli, kahi i loaʻa i nā ʻano kiʻekiʻe.
Ma hea e hoʻohana ai i kēia mea?
Nā Baluna Leʻaleʻa: Hoʻohana mua ʻia ka Helium e hoʻoulu i nā baluna, e lana ai lākou i ka lewa. He koho kaulana kēia no nā hoʻolauleʻa, nā pāʻina a me nā hanana.
Nā Baluna Lewa: Hoʻohana ʻia nā baluna wā piha i ka Helium e hōʻiliʻili i ka ʻikepili o ka lewa ma nā haʻawina meteorological a me ke aniau. E hoʻomaopopo he ʻokoʻa paha nā noi a me nā lula no ka hoʻohana ʻana i ka helium ma ka ʻāina, ka ʻoihana a me ke kumu.
Nā Mokulele: ʻO nā mea ʻoi aku ka māmā ma mua o ka ea o ka helium e kūpono ia no ka hāpai ʻana i nā mokulele a me nā mea hoʻokele. Hoʻohana mau ʻia kēia mau kaʻa i ka hoʻolaha, nā kiʻi lewa a me ka noiʻi ʻepekema.
Cryogenics: Hoʻohana ʻia ka Helium ma ke ʻano he mea hoʻomaha i nā ʻōnaehana cryogenic. ʻO ia ke kuleana no ka mālama ʻana i ka noiʻi ʻepekema, nā mīkini kiʻi lāʻau lapaʻau (e like me ka MRI scanners) a me ka superconducting magnets anu.
Welding: Hoʻohana mau ʻia ka Helium ma ke ʻano he kinoea pale i nā kaʻina hana kuʻi ʻana e like me ka tungsten inert gas (TIG). Kōkua ia i ka pale ʻana i ka wahi welding mai nā kinoea ea a hoʻomaikaʻi i ka maikaʻi weld.
Leak Detection: Hoʻohana ʻia ka Helium ma ke ʻano he tracer gas e ʻike ai i nā leaks i nā ʻōnaehana like ʻole e like me ka paipu, nā ʻōnaehana HVAC, a me nā mea hoʻoheheʻe. Hoʻohana ʻia nā mea ʻike leak helium e ʻike pono a loaʻa i nā leaka.
ʻO nā hui hanu: Hiki i nā mea luʻu a me nā astronauts ke hoʻohana i nā hui heliox, e like me ka heliox a me ka trimix, e pale aku i nā hopena maikaʻi ʻole o ka hanu ʻana i ka ea kiʻekiʻe ma ka hohonu a i ʻole ka lewa.
Noiʻi ʻepekema: Hoʻohana ʻia ka Helium i nā ʻano hoʻokolohua ʻepekema a me nā noi noiʻi, me ka cryogenics, ka hoʻāʻo ʻana i nā mea waiwai, ka spectroscopy nuclear magnetic resonance (NMR), a ma ke ʻano he mea lawe kinoea i loko o ka chromatography kinoea.
E hoʻomaopopo he ʻokoʻa paha nā noi a me nā lula no ka hoʻohana ʻana i kēia mea/huahana ma muli o ka ʻāina, ka ʻoihana a me ke kumu. E hahai mau i nā alakaʻi palekana a e nīnau i kahi loea ma mua o ka hoʻohana ʻana i kēia mea / huahana i kekahi noi.
