Helium bụ gas na-adịghị ahụkebe nke nwere usoro kemịkal Ọ, enweghị agba, enweghị isi, gas na-enweghị ụtọ, enweghị ọkụ, anaghị egbu egbu, nke nwere oke okpomọkụ nke -272.8 degrees Celsius na nrụgide dị egwu nke 229 kPa. Na nkà mmụta ọgwụ, helium nwere ike iji na mmepụta nke elu-ike ike ahụ ike urughuru ibé, helium-neon lasers, argon helium mma, na ndị ọzọ ọgwụ, nakwa dị ka ọgwụgwọ nke ụkwara ume ọkụ, na-adịghị ala ala obstructive pulmonary ọrịa na ọrịa ndị ọzọ. Tụkwasị na nke a, enwere ike iji helium mee ihe maka imaging resonance magnetik, cryogenic freezing, na ule nkwụsị gas.
Ngwa kachasị nke helium na ngalaba ahụike gụnyere:
1, MRI imaging: Helium nwere ihe na-agbaze na-esi ísì ụtọ na-esi ísì ụtọ, ọ bụkwa naanị ihe na-eme ka ọ sie ike na nrụgide ikuku na 0 K. Liquefied helium nwere ike iru ala okpomọkụ dị nso na zero zuru oke (banyere -273.15 ° C) mgbe ugboro ugboro. jụrụ na pressurization. Teknụzụ okpomọkụ dị ala na-eme ka a na-eji ya eme ihe na nyocha ahụike. Ihe onyonyo resonance magnet na-adabere na helium mmiri mmiri na-eme ka magnetik na-eme ka ọ mepụta oghere ndọta nwere ike ijere ụmụ mmadụ ozi. Ụfọdụ ihe ọhụrụ ọhụrụ na-adịbeghị anya nwere ike ibelata ojiji nke helium, mana helium ka dị mkpa maka ịrụ ọrụ nke ngwa MRI.
2.Helium-neon laser: Helium-neon laser bụ ọkụ na-acha uhie uhie monochromatic nke nwere nchapụta dị elu, ntụziaka dị mma na ike dị elu. N'ikwu okwu n'ozuzu, ọkụ helium-neon laser dị ala enweghị mmetụta na-ebibi ihe n'ahụ mmadụ, ya mere a na-eji ya eme ihe na ụlọ ọgwụ. Ihe na-arụ ọrụ nke helium-neon laser bụ helium na neon. N'ọgwụgwọ ahụike, a na-eji laser helium-neon dị ala na-eme ka ọkụ na-egbuke egbuke ebe, ebe isi nkwọcha, ebe ọnyá, ọnyá na ihe ndị ọzọ. Ọ nwere mgbochi mkpali, mgbochi itching, ntutu isi, na-akwalite uto nke granulation na epithelium, na accelerate ọgwụgwọ nke ọnya na ọnya. Ọbụna n'ihe gbasara ahụike ahụike, helium-neon laser emewo ka ọ bụrụ "ngwá ọrụ mara mma" dị irè. Ihe na-arụ ọrụ laser Helium-neon bụ helium na neon, nke helium bụ gas inyeaka, neon bụ gas na-arụ ọrụ.
3.Argon-helium mma: argon helium mma na-ejikarị na-adakarị ọgwụ ngwá ọrụ, bụ argon helium oyi mwepu technology eji na ahụike ubi nke crystallization. Ka ọ dị ugbu a, ọtụtụ ụlọ ọgwụ ụlọ nwere ụdị argon helium mma cryotherapy kacha ọhụrụ. Ụkpụrụ bụ ụkpụrụ Joule-Thomson, ntụgharị mmetụta na-ekpo ọkụ gas. Mgbe a na-ewepụta gas argon ngwa ngwa n'ọnụ ọnụ agịga ahụ, anụ ahụ na-arịa ọrịa nwere ike oyi na -120 ℃ ~ -165℃ n'ime sekọnd iri. Mgbe a na-ahapụ helium ngwa ngwa n'ọnụ ọnụ agịga ahụ, ọ na-emepụta ngwa ngwa na-emegharị ngwa ngwa, na-eme ka bọọlụ ice na-agbaze ngwa ngwa ma kpochapụ etuto ahụ.
4, Nchọpụta nkwụsị nke gas: Nchọpụta nkwụsị nke helium na-ezo aka na usoro iji helium dị ka gas tracer iji chọpụta ntanye na ngwugwu dị iche iche ma ọ bụ usoro akara site na ịlele ntinye ya mgbe ọ gbapụrụ n'ihi nkwụsị. Ọ bụ ezie na ọ bụghị naanị na teknụzụ a na-eji na ụlọ ọrụ ọgwụ na ngwaọrụ ọgwụ, a na-ejikwa ya nke ọma na mpaghara ndị ọzọ. Mgbe a bịara n'ịchọpụta nkwụsị nke helium na ụlọ ọrụ ọgwụ, ụlọ ọrụ ndị nwere ike ịnye nsonaazụ ọnụọgụ nke a pụrụ ịdabere na ya na nke ziri ezi nwere ike imeziwanye usoro nnyefe ọgwụ ha. Ọ na-azọpụta ego na oge ma mee ka nchekwa dịkwuo mma; n'ime ụlọ ọrụ ngwaọrụ ahụike, ihe a na-elekwasị anya bụ na nnwale iguzosi ike n'ezi ihe ngwugwu. Nnwale ntanye nke helium na-ebelata ihe ize ndụ nke ọdịda ngwaahịa maka ndị ọrịa na ndị ọrụ ahụike yana ihe egwu nke ụgwọ ngwaahịa maka ndị nrụpụta.
6, Ọgwụgwọ nke ụkwara ume ọkụ: Ebe ọ bụ na 1990s, e nwere ọmụmụ nke helium-oxygen ngwakọta maka ọgwụgwọ nke ụkwara ume ọkụ na akụkụ okuku ume ọrịa. N'ikpeazụ, ọnụ ọgụgụ dị ukwuu nke ọmụmụ ekwenyela na ngwakọta helium-oxygen na-arụ ọrụ nke ọma na ụkwara ume ọkụ, COPD, na ọrịa obi pulmonary. Ngwakọta helium-oxygen dị elu nwere ike iwepụ mbufụt nke ụzọ ikuku. Nkuku nke ngwakọta helium-oxygen n'otu nrụgide nwere ike ịkwanye akpụkpọ ahụ mucous nke trachea n'ụzọ anụ ahụ ma kwalite nchụpụ nke phlegm miri emi, na-enweta mmetụta nke mgbochi mbufụt na atụmanya.
