I-Helium yigesi enqabileyo kunye nefomula yekhemikhali Yena, igesi engenambala, engenavumba, engenancasa, engenakutsha, engenabuthi, eneqondo lokushisa elibalulekileyo -272.8 degrees Celsius kunye noxinzelelo olunzima lwe-229 kPa. Kwiyeza, i-helium ingasetyenziselwa ukuveliswa kwezixhobo zonyango ezinamandla aphezulu, i-helium-neon lasers, i-argon helium iimela, kunye nezinye izixhobo zonyango, kunye nokunyangwa kwe-asthma, isifo esingapheliyo se-pulmonary obstructive kunye nezinye izifo. Ukongeza, i-helium ingasetyenziselwa ukucinga ngemagnethi, ukukhenkceza kwe-cryogenic, kunye novavanyo lokuqina kwegesi.
Ezona zicelo ziphambili ze-helium kwicandelo lezonyango ziquka:
I-1, i-MRI imaging: I-Helium inomlinganiselo ophantsi kakhulu wokuncibilika kunye nokubilisa, kwaye iyona nto yodwa engaqini kwixinzelelo lwe-atmospheric kunye ne-0 K. I-helium ene-Liquefied inokufikelela kumaqondo okushisa aphantsi kufuphi ne-zero epheleleyo (malunga -273.15 ° C) emva kokuphindaphindiweyo ukupholisa kunye noxinzelelo. Le teknoloji yeqondo lokushisa eliphantsi kakhulu yenza ukuba isetyenziswe ngokubanzi kwi-scanning yezonyango. Imagnethi iresonance imaging ixhomekeke kulwelo lwehelium encapsulating superconductingmagnets ukuvelisa amandla emagnethi anokusebenzela uluntu. Izinto ezintsha zamva nje zinokunciphisa ukusetyenziswa kwe-helium, kodwa i-helium isabalulekile ekusebenzeni kwezixhobo ze-MRI.
I-2.I-laser ye-Helium-neon: I-laser ye-Helium-neon ukukhanya okubomvu kwe-monochromatic kunye nokukhanya okuphezulu, ulwalathiso oluhle kunye namandla agxininiswe kakhulu. Ngokuqhelekileyo, i-laser ye-helium-neon ene-low-power ayinayo impembelelo eyonakalisayo kumzimba womntu, ngoko isetyenziswa ngokubanzi kwiiklinikhi. Izinto ezisebenzayo ze-helium-neon laser ziyi-helium kunye neon. Kunyango lwezonyango, i-laser ye-helium-neon enamandla ephantsi isetyenziselwa ukukhupha iindawo ezivuthayo, iindawo ze-bald, iindawo ezinezilonda, amanxeba njalo njalo. I-anti-inflammatory, anti-itching, ukukhula kweenwele, ikhuthaza ukukhula kwe-granulation kunye ne-epithelium, kwaye ikhawuleza ukuphulukiswa kwamanxeba kunye nezilonda. Nangona kwintsimi ye-aesthetics yonyango, i-helium-neon laser yenziwe "isixhobo sobuhle" esisebenzayo. Izinto zokusebenza ze-laser ze-helium-neon yi-helium kunye neon, apho i-helium yigesi encedisayo, i-neon iyona gesi esebenzayo.
I-3.Argon-helium imela: imela ye-argon ye-helium isetyenziswa ngokuqhelekileyo kwizixhobo zonyango lwezonyango, i-argon helium ebandayo yobuchwephesha obubodwa obusetyenziswa kwintsimi yonyango ye-crystallization. Okwangoku, izibhedlele ezininzi zasekhaya zinemodeli yamva nje ye-argon helium knife cryotherapy centre. Umgaqo ngumgaqo-siseko we-Joule-Thomson, okt i-gas throttling effect. Xa igesi ye-argon ikhutshwa ngokukhawuleza kwincam yenaliti, izicubu ezigulayo zinokukhenkceza ukuya ku -120℃~-165℃ phakathi kwemizuzwana elishumi. Xa i-helium ikhutshwa ngokukhawuleza kwincam yenaliti, ivelisa ukufudumala ngokukhawuleza, okubangela ukuba ibhola lomkhenkce linyibilike ngokukhawuleza kwaye liphelise ithumba.
I-4, Ukufunyanwa kokuqina kwegesi: Ukufunyanwa kwe-helium ukuvuza kubhekiselele kwinkqubo yokusebenzisa i-helium njenge-tracer gas ukubona ukuvuza kwiiphakheji ezahlukeneyo okanye iinkqubo zokutywinwa ngokulinganisa ukugxilwa kwayo xa ibaleka ngenxa yokuvuza. Ngelixa obu buchwepheshe bungasetyenziswanga kuphela kumashishini amayeza kunye nezixhobo zonyango, bukwasetyenziswa kakuhle nakweminye imimandla. Xa kuziwa ekubonweni kokuvuza kwe-helium kwishishini lamachiza, iinkampani ezinokubonelela ngeziphumo ezithembekileyo nezichanekileyo zobuninzi zinokuphucula umgangatho weenkqubo zabo zokuhanjiswa kweziyobisi. Igcina imali kunye nexesha kwaye iphucula ukhuseleko; kushishino lwezixhobo zonyango, eyona ngqwalasela ikuvavanyo lwengqibelelo yephakheji. Ukuvavanywa kokuvuza kwe-Helium kunciphisa umngcipheko wokungaphumeleli kwemveliso kwizigulane kunye nabasebenzi bezonyango, kunye nomngcipheko woxanduva lwemveliso kubavelisi.
6, Unyango lwesifuba: Ukusukela ngeminyaka yoo-1990, kuye kwakho izifundo zemixube ye-helium-oksijini yonyango lwe-asthma kunye nezifo zokuphefumla. Emva koko, inani elikhulu lophononongo luqinisekisile ukuba imixube ye-helium-oksijini inokusebenza kakuhle kwi-asthma, COPD, kunye nesifo sentliziyo yemiphunga. Uxinzelelo oluphezulu lwe-helium-oksijeni imixube inokuphelisa ukuvuvukala kweendlela zomoya. Ukuphefumla umxube we-helium-oksijeni kuxinzelelo oluthile kunokugungxula ngokwasemzimbeni i-mucous membrane kunye nokukhuthaza ukugxothwa kwe-phlegm enzulu, ukufikelela kwisiphumo sokuchasana nokudumba kunye ne-expectoration.
