Cryogenic kua yog cov tshuaj uas tau khaws cia ntawm qhov kub tsawg zaus, feem ntau qis dua -150 degrees Celsius. Cov kua dej no, Ruljson.Queue ua kua nitrogen, kua helium, thiab kua oxygen, yog siv nyob rau hauv ntau yam kev lag luam, kev kho mob, thiab kev thov kho mob, thiab kev tshawb fawb thiab scientific. Txawm li cas los xij, khaws cov kua cannenic yuav tsum muaj kev saib xyuas tshwj xeeb thiab kev ceev faj vim lawv qhov kev kub ntxhov heev thiab muaj kev phom sij heev thiab muaj kev phom sij heev.
Khaws cov kua cryogenic kom nyab xeeb, nws yog ib qho tseem ceeb uas yuav tau siv cov thawv tshwj xeeb thiab cov hau kev cia tsim los daws cov huab cua sov no. Ib hom khoom ntim siv rauKhaws cov kua roj cryogenicyog lub tshuab nqus tsev-insulated. Cov dewars muaj cov nkoj sab hauv uas tuav cov kua roj cryogenic, ncig los ntawm lub nkoj sab nraud nrog lub tshuab nqus ntawm ob. Lub tshuab nqus tsev no ua haujlwm ua rwb thaiv tsev kom cov kua ntawm nws qhov kub thiab txias thiab tiv thaiv tshav kub los ntawm kev nkag mus hauv lub khob.
ThaumKhaws cov kua roj cryogenic hauv ib lwg, Nws yog qhov tseem ceeb kom ntseeg tau tias lub thawv ntim tau khaws cia hauv qhov chaw muaj pa kom tiv thaiv kom tsis txhob muaj cov pa roj twg uas yuav yaj los ntawm cov kua. Ib qho ntxiv, thaj chaw cia yuav tsum tau nruab nrog cov pa roj kom pom thiab cua tshuab los saib xyuas thiab tshem tawm cov pa roj nti.
Nws tseem yog qhov tseem ceeb los tuav cov kua roj cryogenic nrog kev saib xyuas kom tsis txhob muaj kev phom sij. Thaum sau lub lwg nrog cov kua roj cryogenic, cov txheej txheem yuav tsum tau nqa tawm hauv qhov chaw tiv thaiv zoo, thiab cov hnab looj tes kom zoo li cov hnab looj tes thiab hnab looj tes, yuav tsum hnav. Ib qho ntxiv, cov txheej txheem ua yuav tsum tau ua los ntawm cov neeg ua haujlwm uas paub txog kev tsim nyog thiab khaws cia ntawm cov kua roj cryogenic.
Ntxiv rau kev siv cov khoom ntim yog thiab cov txheej txheem tuav, nws yog ib qho tseem ceeb kom ua raws cov lus qhia tshwj xeeb rau cov kua sib txawv ntawm cov kua cryogenic sib txawv. Piv txwv li, ua kua nitrogen, uas feem ntau siv nyob rau hauv chaw kho mob thiab cov chaw kho mob, yuav tsum tau muab cia rau thaj chaw zoo ntawm cov khoom ntawm cov chaw tiv thaiv. Nws yog qhov tseem ceeb kom ntseeg tau tias qhov chaw cia tau nruab nrog cov khoom siv nyem kom tiv thaiv kev tsim lub zog hauv lub khob.
Thaum khaws cov kua helium, uas feem ntau siv hauv kev tshawb fawb cryogenic thiab superconducting kom khaws cia thaj chaw cia kom zoo thiab pub dawb ntawm cov ntaub ntawv sib txuas. Ib qho ntxiv, kev ceev faj yuav tsum tau coj los tiv thaiv kev tshaj tawm cov thawv ntim khoom, raws li cov kua helium tau nce zuj zus thaum sov.
Txhawm rau khaws cov pa oxygen, uas yog siv hauv kev kho mob thiab kev lag luam, kev ntsuas kev nyab xeeb yuav tsum tau ua raws li nws cov oxidizing tej yam. Thaj chaw cia yuav tsum muaj cov khoom siv tau zoo thiab tsis muaj cov khoom siv tawm los tiv thaiv cov pa oxygen-enricked, uas tuaj yeem ua rau hluav taws kub txaus ntshai.
Ntxiv rau kev ua raws li cov lus qhia no, nws yog qhov tseem ceeb rau kev soj ntsuam tsis tu ncua thiab khaws cia ntim khoom thiab cov cuab yeej siv rau cov kua roj cryogenic. Qhov no suav nrog kev kuaj xyuas cov cim kev puas tsuaj lossis hnav, kom cov khoom siv nyem kom zoo, thiab cov kua roj kev kom tiv thaiv tau ntau dua.
Zuag qhia tag nrho, khaws cov kua roj cannenic yuav tsum ua tib zoo mloog kom nthuav dav thiab ua raws li cov lus qhia kev nyab xeeb tshwj xeeb. Los ntawm kev siv cov txheej txheem uas yog, cov txheej txheem khaws cia, thiab cov kev phom sij uas cuam tshuam nrog cov kua nplua nuj tuaj yeem txo qis kev nyab xeeb, tso cai rau lawv txoj kev nyab xeeb thiab siv tau ntau yam kev siv.
