Ua kua nitrogen: nitrogen roj hauv lub xeev ua kua. Inert, tsis muaj xim, tsw ntxhiab, tsis yog-corrosive, tsis-flamming, tsis tshua muaj neeg cryogenic kub. Nitrogen cov ntaub ntawv feem ntau ntawm cov cua (78.03% los ntawm ntim thiab 75.5% los ntawm qhov hnyav) .nitrogen tsis muaj zog thiab tsis txhawb kev sib txuas. Frostbite tshwm sim los ntawm ntau dhau endothermic tiv tauj thaum vaporization.
Ua kua nitrogen yog qhov chaw txias yooj yim. Vim nws cov khoom muaj txiaj ntsig, ua kua nitrogen tau yooj yim tau them ntau dua thiab ntau dua kev saib xyuas thiab paub los ntawm cov neeg. Nws tau muaj ntau dua thiab ntau dua dav siv hauv tsiaj tus txiv, kev lag luam kev kho mob, kev lag luam khoom noj, kev lag luam kev lag luam, thiab cryogenic tshawb fawb teb. Hauv cov khoom siv hluav taws xob, metallurgy, aerospace, machinery manufacturing thiab lwm yam ntawm daim ntawv thov tau nthuav dav thiab txhim kho.
Ua kua nitrogen cryogenic microbial sau cov kev txawj
Lub hauv paus ntsiab lus ntawm cov kua Nitrogen Lilling cov kab mob nyob rau ntawm -196 ℃, yog kom sau cov kab mob hauv qab -130 ℃ .macrofungi yog ib pawg tseem ceeb ntawm fungi (fungi uas ua Cov txiv ntoo loj hauv fungi, feem ntau hais txog cov nceb lossis nceb hauv qhov kev pom dav dav). Ntau hom muaj cov kev noj haus muaj txiaj ntsig zoo thiab cov nqi tshuaj, thiab lawv muaj cov ntawv thov kev cia siab ntawm Fungi. Tsis tas li ntawd, qee cov fungi loj tuaj yeem tso tseg cov ntoo tuag, uas yog kev tswj hwm cov khoom siv ntuj ua si thiab tuaj yeem tsim kho thiab siv rau kev lag luam ib puag ncig. Qee lub fungi loj tuaj yeem ua rau cov nroj tsuag ntoo lossis kev puas tsuaj rau ntau yam ntoo. Kev txhim kho ntawm kev nkag siab ntawm cov pathogenic fungi yog conducive rau kev tiv thaiv thiab tshem tawm ntawm kev tsim txom. Tus exemopl sau los ntawm macrofungi yog qhov tseem ceeb ntawm cov khoom muaj caj ces, thiab kev sib qhia ntawm biodiversity nyob rau ntau qhov chaw
Kev caj ces ciaj sia ntawm kev ua liaj ua teb
Shanghai tau nqis peev ntau dua 41 lab yuan los teeb tsa thiab tso cov ntaub ntawv sib xyaw ua ke hauv cov noob ntsha hauv Suav teb. Lub noob lag luam kev lag luam, uas muaj lub peev xwm qhib lub ntiaj teb kev ua lag luam, yuav siv cov noob txhab nyiaj ua ib qho chaw ntawm kev ua liaj ua teb ua liaj ua teb. Lub tuam txhab Shanghai Biological Biological Bank, nrog tag nrho thaj tsam ntawm 3,300 square metres, yuav nyob hauv Shanghai Academy ntawm kev kawm txog kev ua liaj ua teb. Nws yuav sau tsib hom ua liaj ua teb muaj tshuaj tua kab mob xws li cov khoom cog ntoo, cog cov tsiaj thiab cov khoom siv caj ces tshuab.
Tshuaj Txias
Cov tshuaj kho mob sai yog kev txhim kho cov qog ntshav, tawv nqaij, thiab lwm yam ntawm pob txha tsis muaj sia nyob ntawm Hematopoietic qia hlwb. Nyob rau hauv qhov txias thiab khov cov txheej txheem ntawm kev kuaj cov roj ntsha, thaum lub theem hloov ntawm kua rau khoom, qee qhov kub yuav tawm thiab qhov kub yuav nce. Cov txheej txheem khov ua yam tsis tau tswj tus nqi cua txias yuav ua rau kev tuag ntawm cov qauv kev teeb tsa. Tus yuam sij los txhim kho cov kev muaj sia nyob ntawm cov qauv khov kho kom haum rau theem kev hloov pauv kom txias thaum lub sij hawm hloov pauv, mus rau suppress qhov ntsuas kub nce Theem hloov pauv thiab ua kom lub hlwb kis tau hloov chaw nyob ntsiag to thiab nrawm.
Cov tshuaj kho mob
Ua kua nitrogen yog ib tug dav siv cov tub yees hauv cryosurgery. Nws yog lub tub yees txias uas tau tsim kom deb li deb, thiab thaum koj txhaj nws rau hauv lub tshuab kho mob cryogenic kho mob, nws ua zoo li lub hau taub hau, thiab koj tuaj yeem ua ib qho kev phais mob. Mixother yog kev kho mob uas siv cryogenic kub kom tawg cov qauv lesion. Raws li qhov hloov pauv ntawm cov ntsuas kub ntawm lub xov tooj ntawm tes, ua kom khov, hluav taws xob, yuav ua rau lub cev tsis muaj ntshav, yog li ntawd cov ntshav tsis muaj ntshav, ua rau cov ntshav hauv zos Cell hypoxia tuag.
Hl cryogenic khoom
Hl cryogenic khoomuas tau tsim nyob rau xyoo 1992 yog ib qho kev koom nrog homHl cryogenic cov khoom siv tuam txhab cryogenic khoom Co., LtdCov. Ua cov khoom siv cryogenic tau cog lus rau cov qauv siv thiab tsim cov tshuab hluav taws xob siab cryogenic piping system thiab cuam tshuam cov khoom siv txhawb nqa kom tau raws li cov neeg siv khoom ntau. Lub tshuab nqus tsev insulated yeeb nkab thiab yoog raws tau tsim nyob rau hauv lub tshuab hluav taws xob siab tshwj xeeb, uas yog siv rau kev hloov pauv ntawm cov pa oxygen, ua kua nitrogen , Ua Kua Argon, kua hydrogen, kua helium, liquefas roj ceg thiab liquefied xwm roj lng.
Cov khoom series ntawm lub tshuab nqus tsev, nqus cov yeeb nkab, nqus plua plav hauv txoj kev kho mob, siv rau cov khoom siv ua kua tsis zoo nkauj, ua kua argon, kua hydrogen, kua Helium, ceg thiab lng, thiab cov khoom lag luam no tau txais kev pab rau cov khoom siv hluav taws xob cryogenic (piv txwv li cov khoom siv Tshawb nrhiav etc.
