Iko kushandiswa kukuru kweHelium munharaunda yekurapa

Helium igasi risingawanzoitiki rine chimiro chemakemikari Iye, gasi risina ruvara, risina kunhuwa, risingarapike, risingabatike, risina chepfu, rine tembiricha yakaoma ye -272.8 madhigirii celsius uye dzvinyiriro yakaoma ye229 kPa. Mumushonga, helium inogona kushandiswa mukugadzirwa kwepamusoro-simba rekurapa particle matanda, helium-neon lasers, argon helium mapanga, uye zvimwe midziyo yezvokurapa, uyewo mukurapa asima, chisingaperi obstructive pulmonary chirwere uye zvimwe zvirwere. Pamusoro pezvo, helium inogona kushandiswa kuita magineti resonance imaging, cryogenic freezing, uye gasi-tightness test.

Iko kushandiswa kukuru kwehelium mumunda wekurapa kunosanganisira:

1, MRI imaging: Helium ine nzvimbo yakaderera zvikuru yekunyunguduka uye kuvira, uye ndiyo chete chinhu chisingasimbisi pamhepo yemhepo uye 0 K. Liquefied helium inogona kusvika kumatembiricha akadzika pedyo neabsolute zero (inenge -273.15 ° C) mushure mekudzokororazve. kutonhora uye kudzvinyirira. Iyi tekinoroji yepamusoro-yakaderera tekinoroji inoita kuti ishandiswe zvakanyanya mukuongororwa kwekurapa. Magnetic resonance imaging inotsamira pane liquid helium encapsulating superconducting magineti kugadzira magineti anogona kushandira vanhu. Zvimwe zvitsva zvitsva zvinogona kuderedza kushandiswa kwehelium, asi helium ichiri kukosha pakushanda kweMRI zviridzwa.

2.Helium-neon laser: Helium-neon laser inonzi monochromatic dzvuku chiedza chine kupenya kwepamusoro, kutungamirirwa kwakanaka uye simba rakanyanyisa. Kazhinji kutaura, yakaderera-simba helium-neon laser haina inoparadza pamuviri wemunhu, saka inoshandiswa zvakanyanya mukuita kwekiriniki. Zvinhu zvinoshanda zve helium-neon laser ndeye helium uye neon. Mukurapa kwekurapa, yakaderera simba helium-neon laser inoshandiswa kumisa kuzvimba nzvimbo, nzvimbo dzemhanza, nzvimbo dzine maronda, maronda uye zvichingodaro. Iine anti-inflammatory, anti-itching, kukura kwebvudzi, inokurudzira kukura kwegranulation uye epithelium, uye inokurumidza kuporesa maronda nemaronda. Kunyangwe mumunda wekurapa aesthetics, helium-neon laser yakagadzirwa kuva "inoyevedza chiridzwa" chinoshanda. Helium-neon laser inoshanda zvinhu ndeye helium uye neon, iyo helium ndiyo yekubatsira gasi, neon ndiyo huru inoshanda gasi.

3.Argon-helium banga: argon helium banga inowanzoshandiswa mumakiriniki ezvokurapa maturusi, is argon helium inotonhora yekuzviparadzanisa tekinoroji inoshandiswa mune zvekurapa zvekristaro. Parizvino, zvipatara zvakawanda zvepamba zvine mhando yazvino yeargon helium knife cryotherapy centre. Nheyo yacho ndeye Joule-Thomson musimboti, kureva gasi throttling athari. Kana argon gasi ichikurumidza kuburitswa mumuromo wetsono, nyama inorwara inogona kuomeswa nechando kusvika -120 ℃ ~ -165 ℃ mukati memasekondi gumi. Apo helium inokurumidza kusunungurwa pamucheto wetsono, inogadzira kukurumidza kudziya, zvichiita kuti bhora rechando rinyunguduke nekukurumidza uye kubvisa bundu.

4, Gasi Tightness Detection: Helium leak yekuona inoreva maitiro ekushandisa helium setracer gasi kuona kubuda mumapakeji akasiyana siyana kana masisitimu ekuvharisa nekuyera kusungwa kwayo kana yatiza nekuda kwekudonha. Nepo tekinoroji iyi isingango shandiswe mumaindasitiri emishonga nemishonga, inoshandiswawo zvakanaka mune mamwe minda. Kana zvasvika pakuonekwa kwehelium leak muindasitiri yemishonga, makambani anogona kupa akavimbika uye akakwana mhedzisiro yehuwandu anogona kuvandudza kunaka kwemaitiro avo ekupa zvinodhaka. Inochengetedza mari uye nguva uye inovandudza kuchengeteka; muindasitiri yezvishandiso zvekurapa, chinonyanya kutariswa chiri pakuyedzwa kwekuvimbika kwepakeji. Helium kuvuza kuyedzwa kunoderedza njodzi yekutadza kwechigadzirwa kune varwere nevashandi vekurapa, pamwe nenjodzi yemhosva yechigadzirwa kune vanogadzira.

6, Kurapwa kweasthma: Kubva kuma1990, kwave nezvidzidzo zvemusanganiswa wehelium-okisijeni pakurapa asima uye zvirwere zvekufema. Zvadaro, nhamba huru yezvidzidzo zvakasimbisa kuti helium-oxygen musanganiswa une kushanda kwakanaka muasthma, COPD, uye pulmonary heart disease. High-pressure helium-oxygen misanganiswa inogona kubvisa kuzvimba kwemhepo. Inhalation ye helium-oxygen musanganiswa pane imwe dzvinyiriro inogona kupenengura mucous membrane yetrachea uye kukurudzira kudzingwa kweyakadzika phlegm, kuwana mhedzisiro yekurwisa-kuzvimba uye expectoration.
