Ua kua nitrogen yog qhov sib kis yooj yim. Vim nws cov yam ntxwv tshwj xeeb, ua kua nitrogen tau maj mam tau txais kev saib xyuas tsiaj, kev tshawb fawb, kev lag luam kev lag luam, thiab tsawg kub tshawb fawb. , hauv Electronics, metallurgy, aerospace, machinery manufacturing thiab lwm yam ntawm kev nthuav dav txuas ntxiv thiab kev loj hlob.
Ua kua nitrogen yog tam sim no dav siv cryogen hauv cryosurgery. Nws yog ib qho ntawm cov tub yees zoo tshaj plaws pom kom deb li deb. Nws tuaj yeem raug txhaj rau hauv cov cuab yeej kho mob cryogenic kho mob, ib yam li lub hau taub hau, thiab nws tuaj yeem ua txhua yam haujlwm. Cryother yog ib txoj kev kho mob uas tsawg yog siv los rhuav tshem cov nqaij mos. Vim tias qhov ntsuas kub hloov kho qhov kub, muaju yog tsim rau sab hauv thiab sab nraud, ua rau cov pa hluav taws xob hauv zos, thiab cov pa roj ntsha ua rau lub cev tsis txhob tuag vim hypoxia.
Ntawm ntau txoj kev khaws cia, cryopreservation yog cov feem ntau siv thiab cov nyhuv yog qhov tseem ceeb heev. Raws li ib qho ntawm cov txheej txheem cryopreservation, ua kua nitrogen sai-khov tau ntev tau txais los ntawm kev ua zaub mov ua khoom noj. Vim tias nws tuaj yeem paub txog huab ultra-nrawm ntawm qhov kub thiab txias thiab txias rau cov zaub mov khov, kom cov zaub mov tuaj yeem zoo tshaj plaws tom qab yaj. Txhawm rau thawj lub xeev tshiab thiab thawj cov khoom noj muaj txiaj ntsig, qhov zoo ntawm cov zaub mov khov tau zoo dua, yog li nws tau qhia txog kev loj hlob sai sai hauv kev lag luam nrawm nrawm.
Tsawg-kub pulverization ntawm cov zaub mov yog kev tsim khoom noj khoom haus khoom lag luam tshiab hauv cov xyoo tsis ntev los no. Cov thev naus laus zis no tshwj xeeb yog tsim nyog rau kev ua cov zaub mov muaj ntxhiab nrog cov txiaj ntsig siab, cov ntsiab lus muaj txiaj ntsig zoo thiab cov khoom qab zib siab. Siv cov kua nitrogen rau cov pulverization tsawg, cov pob txha, nqaij, lub plhaub ntawm cov khoom tiav tau zoo thiab tiv thaiv nws cov khoom noj muaj txiaj ntsig zoo. Piv txwv li, hauv Nyij Pooj, Seaweed, Chitin, Cov Khoom Siv, uas tau ua tiav cov khoom lag luam kom zoo li 100UM lossis tsawg dua, thiab cov khoom noj muaj txiaj ntsig qub yog khaws cia.
