Thaum koj xav txog kev cais cua, tej zaum koj yuav xav txog cov pej thuam loj loj uas ua kom cua txias los ua pa oxygen, nitrogen, lossis argon. Tab sis tom qab cov xwm txheej ntawm cov tuam txhab loj no, muaj ib qho thev naus laus zis tseem ceeb, feem ntau tsis quav ntsej txog uas ua rau txhua yam khiav tau zoo:Cov Kav Dej Nqus Tsev(VIP) thiabCov Hose Uas Muaj Cov Khoom Siv Nqus TsevCov no tsis yog tsuas yog cov kav dej xwb; lawv yog cov txheej txheem tsim kho kom raug uas tseem ceeb rau kev ua haujlwm zoo thiab kev nyab xeeb ntawm txhua lub tsev niaj hnub noKev Sib Cais Huab Cuaunit (UA).

Cia peb hais meej meej: cryogenics - kev tshawb fawb txog qhov txias heev - yog qhov ua rau kev sib cais huab cua ua tau. Peb tab tom tham txog qhov kub thiab txias poob qis dua -180 ° C (-292 ° F) kom ua rau huab cua ua kua. Qhov kev sib tw loj tshaj plaws? Khaws qhov txias heev ntawd rau hauv. Qhov kub ntawm ib puag ncig yog tus yeeb ncuab, sim ua kom sov thiab ua kom cov kua cryogenic muaj nqis xws li kua nitrogen (LN2) thiab kua oxygen (LOX). Qhov no yog qhov chaw uas lub khawv koob ntawmCov Kav Dej Nqus Tsev(VIPs) los ua si. Xav txog lawv zoo li lub raj mis thermos muaj zog heev. Los ntawm kev tsim lub tsho nqus tsev ntawm phab ntsa sab hauv thiab sab nraud ntawm lub yeeb nkab, lawv tsim ib qho kev thaiv zoo kawg nkaus tiv thaiv cua sov. Qhov zoo dua cov noCov Kav Dej Nqus Tsev(VIPs) ua haujlwm tau zoo, lub zog tsawg dua raug nkim, thiab tag nrho ASU ua haujlwm tau zoo dua.

Tam sim no, thaum twg tej yam yuav tsum tau tsiv mus? Qhov ntawd yog qhov ntawdCov Hose Uas Muaj Cov Khoom Siv Nqus Tsevua qhov tseem ceeb tshaj plaws. Lawv muab qhov kev ywj pheej tseem ceeb rau kev txuas txhua yam - los ntawm cov zis tseem ceeb ntawm ASU mus rau cov thoob dej cia khoom, txuas cov theem txheej txheem sib txawv, lossis pab txhawb cov haujlwm kho thiab rov ua dua tshiab. Tsis zoo li cov hoses ib txwm muaj, cov noCov Hose Uas Muaj Cov Khoom Siv Nqus Tsevtswj hwm qhov tseem ceeb ntawm cov saw hlau txias cryogenic. Lawv txoj kev tsim kho kom ruaj khov tiv thaiv txhua qhov "kev poob txias" thiab, qhov tseem ceeb, tiv thaiv cov neeg ua haujlwm thiab cov khoom siv los ntawm kev pheej hmoo ntawm kev kub hnyiab txias heev. Yog tias koj tab tom khiav lub chaw sib cais cua, qhov kev ntseeg tau ntawm kojCov Hose Uas Muaj Cov Khoom Siv Nqus Tsevyog qhov tsis sib haum xeeb kiag li; qhov ua tsis tiav ntawm no txhais tau tias lub sijhawm tsis ua haujlwm, kev ua haujlwm tsis zoo, thiab tej zaum yuav muaj xwm txheej kev nyab xeeb.

Nyob rau hauv kev lag luam no, muaj kev nyuaj siab tas li kom ua kom zoo dua qub thiab txo cov nqi. Qhov no ua rau pom tseeb rau qhov zoo thiab cov lus qhia ntawmCov Kav Dej Uas Muaj Cov Khoom Siv Nqus Tsev (VIPs)thiabCov Hose Uas Muaj Cov Khoom Siv Nqus Tsevsiv. Cov chaw tsim khoom pheej tsim kho tshiab, kho cov ntaub ntawv thiab cov txheej txheem tsim kho kom ua rau cov khoom no ruaj khov thiab ua haujlwm tau zoo dua. Rau txhua tus neeg ua haujlwm cog qoob loo, xaiv cov khoom zoo tshaj plawsCov Kav Dej Uas Muaj Cov Khoom Siv Nqus Tsev (VIPs)thiab ntseeg tauCov Hose Uas Muaj Cov Khoom Siv Nqus Tsevtsis yog ib lub tswv yim zoo xwb; nws yog ib qho kev nqis peev zoo uas them nyiaj rau cov khoom huv, lub sijhawm ua haujlwm, thiab kev nyab xeeb ntawm cov neeg ua haujlwm. Kev ntws ntawm cov pa roj hauv ASU yeej nyob ntawm qhov kev ua tau zoo uas xa los ntawm cov kev daws teeb meem hloov pauv cryogenic tseem ceeb no.
