Ntchito zazikulu za Helium pazachipatala

Helium ndi gasi osowa ndi mankhwala chilinganizo Iye, colorless, fungo, mpweya wopanda kukoma, osayaka, sanali poizoni, ndi kutentha kwambiri -272,8 digiri Celsius ndi kuthamanga kwambiri 229 kPa. Mu mankhwala, helium angagwiritsidwe ntchito kupanga mkulu-mphamvu mankhwala tinthu matabwa, lasers helium-neon, mipeni argon helium, ndi zipangizo zina zachipatala, komanso pa matenda a mphumu, aakulu obstructive m'mapapo matenda ndi matenda ena. Kuphatikiza apo, helium imatha kugwiritsidwa ntchito pojambula maginito a resonance, kuzizira kwa cryogenic, komanso kuyesa kulimba kwa gasi.

Ntchito zazikulu za helium pazachipatala ndi izi:

1, kujambula kwa MRI: Helium ili ndi malo otsika kwambiri osungunuka ndi otentha, ndipo ndi chinthu chokhacho chomwe sichimalimbitsa mphamvu ya mlengalenga ndi 0 K. Liquefied helium imatha kufika kutentha kwapansi pafupi ndi zero mtheradi (pafupifupi -273.15 ° C) pambuyo mobwerezabwereza mobwerezabwereza. kuziziritsa ndi pressurization. Tekinoloje yotsika kwambiri yotenthayi imapangitsa kuti igwiritsidwe ntchito kwambiri pakuwunika zamankhwala. Kujambula kwa maginito kumadalira maginito a helium omwe amatsekera maginito akuluakulu kuti apange mphamvu za maginito zomwe zingathe kuthandiza anthu. Zatsopano zaposachedwa zitha kuchepetsa kugwiritsa ntchito helium, koma helium ndiyofunikirabe pakugwiritsa ntchito zida za MRI.

Laser ya 2.Helium-neon: Laser ya Helium-neon ndi kuwala kofiira kwa monochromatic ndi kuwala kwakukulu, kuwongolera bwino komanso mphamvu zambiri. Nthawi zambiri, laser yamphamvu ya helium-neon ilibe mphamvu yowononga thupi la munthu, chifukwa chake imagwiritsidwa ntchito kwambiri pazachipatala. Zinthu zogwira ntchito za helium-neon laser ndi helium ndi neon. Pazachipatala, mphamvu yochepa ya helium-neon laser imagwiritsidwa ntchito poyatsira madera otupa, malo a dazi, malo okhala ndi zilonda, mabala ndi zina zotero. Ali ndi anti-yotupa, odana ndi kuyabwa, kukula kwa tsitsi, amalimbikitsa kukula kwa granulation ndi epithelium, ndipo imathandizira machiritso a zilonda ndi zilonda. Ngakhale m'munda wa aesthetics yachipatala, laser ya helium-neon yapangidwa kukhala "chida chokongola" chothandiza. Helium-neon laser ntchito zinthu ndi helium ndi neon, amene helium ndi mpweya wothandiza, neon ndiye waukulu ntchito mpweya.

3.Argon-helium mpeni: mpeni wa argon helium umagwiritsidwa ntchito kwambiri pazida zamankhwala zamankhwala, ndiukadaulo wa argon helium ozizira kudzipatula womwe umagwiritsidwa ntchito pazachipatala cha crystallization. Pakalipano, zipatala zambiri zapakhomo zili ndi chitsanzo chaposachedwa cha argon helium mpeni cryotherapy center. Mfundo yake ndi mfundo ya Joule-Thomson, mwachitsanzo, kutulutsa mpweya. Pamene mpweya wa argon umatulutsidwa mofulumira kunsonga kwa singano, minofu yodwala imatha kuzizira mpaka -120 ℃ ~ -165 ℃ mkati mwa masekondi khumi. Pamene helium imatulutsidwa mofulumira kunsonga kwa singano, imatulutsa kutentha kwachangu, kuchititsa kuti mpirawo usungunuke mofulumira ndikuchotsa chotupacho.

4, Kuzindikira Kulimba kwa Gasi: Kuzindikira kutayikira kwa Helium kumatanthawuza njira yogwiritsira ntchito helium ngati gasi wofufuza kuti azindikire kutayikira m'maphukusi osiyanasiyana kapena makina osindikizira poyesa kuchuluka kwake pamene akuthawa chifukwa cha kutayikira. Ngakhale luso limeneli silimangogwiritsidwa ntchito m'mafakitale a mankhwala ndi zipangizo zachipatala, limagwiritsidwanso ntchito bwino m'madera ena. Zikafika pakuzindikira kutayikira kwa helium m'makampani opanga mankhwala, makampani omwe angapereke zotsatira zodalirika komanso zolondola zamachulukidwe amatha kupititsa patsogolo machitidwe awo operekera mankhwala. Zimasunga ndalama ndi nthawi ndikuwongolera chitetezo; m'makampani opanga zida zamankhwala, cholinga chachikulu ndikuyesa kukhulupirika kwa phukusi. Kuyesa kwa helium kumachepetsa chiopsezo cha kulephera kwa mankhwala kwa odwala ndi ogwira ntchito zachipatala, komanso chiwopsezo cha chiwopsezo cha zomwe opanga amapanga.

6, Chithandizo cha mphumu: Kuyambira m'ma 1990, pakhala pali maphunziro osakanikirana ndi okosijeni wa helium pochiza mphumu ndi matenda opuma. Pambuyo pake, kafukufuku wambiri watsimikizira kuti zosakaniza za helium-oksijeni zimakhala ndi zotsatira zabwino pa mphumu, COPD, ndi matenda a mtima wa m'mapapo. Kuphatikizika kwakukulu kwa helium-oksijeni kumatha kuthetsa kutupa kwa mpweya. Kukoka mpweya wa helium-oksijeni osakaniza pa kuthamanga kwinakwake angathe mwakuthupi mucous nembanemba wa trachea ndi kulimbikitsa kuthamangitsidwa kwambiri phlegm, kukwaniritsa zotsatira za odana ndi kutupa ndi expectoration.
