Nitrogen kua: Nitrogen roj hauv lub xeev ua kua. Inert, tsis muaj xim, tsis muaj ntxhiab, tsis muaj corrosive, tsis-flammable, tsis tshua muaj kub kub. Nitrogen tsim feem ntau ntawm cov huab cua (78.03% los ntawm ntim thiab 75.5% los ntawm qhov hnyav). Nitrogen tsis ua haujlwm thiab tsis txhawb kev sib txuas. Frostbite tshwm sim los ntawm kev sib cuag endothermic ntau dhau thaum vaporization.
Cov kua nitrogen yog ib qho yooj yim txias qhov chaw. Vim nws cov khoom tshwj xeeb, kua nitrogen tau maj mam them nyiaj ntau thiab ntau dua thiab lees paub los ntawm tib neeg. Nws tau siv ntau dua thiab dav siv hauv tsiaj txhu, kev lag luam kho mob, kev lag luam zaub mov, thiab kev tshawb fawb cryogenic. Hauv electronics, metallurgy, aerospace, machinery manufacturing thiab lwm yam ntawm daim ntawv thov tau nthuav dav thiab tsim.
Ua kua nitrogen cryogenic microbial sau txuj ci
Lub hauv paus ntsiab lus ntawm cov kua nitrogen mus tas li txoj kev sau, uas sau cov kab mob ntawm -196 ℃, yog khaws cov kab mob kom zoo los ntawm kev ua kom zoo dua ntawm kev nyiam kom tsis txhob metabolism ntawm cov kab mob hauv qab -130 ℃.Macrofungi yog ib pawg tseem ceeb ntawm cov kab mob (fungi uas tsim. loj fruiting lub cev nyob rau hauv fungi, feem ntau xa mus rau nceb los yog nceb nyob rau hauv ib tug dav kev txiav txim siab). Ntau hom muaj cov nqi noj zaub mov zoo thiab cov nqi kho mob, thiab lawv muaj kev cia siab rau daim ntawv thov kev cia siab ntawm cov fungi. Tsis tas li ntawd, qee cov kab mob loj tuaj yeem txheeb xyuas cov nroj tsuag tuag, uas ua lub luag haujlwm tseem ceeb hauv kev tswj hwm cov khoom siv hauv ntiaj teb thiab kev sib npaug ntawm ecological, thiab tuaj yeem tsim thiab siv rau kev lag luam ntawv thiab kev ua kom huv ib puag ncig. Qee cov fungi loj tuaj yeem ua rau tsob ntoo kab mob lossis ua rau ntau yam khoom siv ntoo puas. Kev txhim kho ntawm kev nkag siab ntawm cov kab mob fungi no yog qhov tsim nyog rau kev tiv thaiv thiab tshem tawm kev puas tsuaj. Kev sau ua piv txwv ntawm macrofungi yog qhov tseem ceeb heev rau kev nyob ntsiag to thiab sau cov khoom siv microbial, kev khaws cia ruaj khov thiab muaj txiaj ntsig ntawm cov khoom siv caj ces, thiab kev sib koom ntawm biodiversity nyob rau hauv ntau qhov chaw.
Genetic ciaj sia taus ntawm cov kab mob ua liaj ua teb
Shanghai tau nqis peev ntau dua 41 lab yuan los teeb tsa thiab xa cov ntaub ntawv dav dav ntawm cov noob qoob loo ua liaj ua teb hauv Suav teb. Kev lag luam noob, uas muaj peev xwm qhib lub lag luam thoob ntiaj teb, yuav siv lub txhab nyiaj gene los ua cov khoom siv yug me nyuam, kev lag luam ua liaj ua teb tau hais. Shanghai Agricultural Biological gene Bank, nrog thaj tsam ntawm 3,300 square metres, yuav nyob hauv Shanghai Academy ntawm Kev Tshawb Fawb Txog Kev Ua Liaj Ua Teb. Nws yuav sau tsib yam kev ua liaj ua teb cov noob caj noob ces suav nrog cov noob qoob loo, cov khoom siv cog qoob loo, cov kab mob ntawm cov tsiaj, cov kab mob microbial thiab cov ntaub ntawv cog noob caj noob ces.
Cov tshuaj txias
Txoj kev loj hlob sai ntawm kev kho mob cryogenic tshuaj tau txhawb txoj kev loj hlob ntawm cov tshuaj hloov pauv, tshwj xeeb tshaj yog nyob rau hauv cov pob txha pob txha, hematopoietic qia hlwb, tawv nqaij, pob txha, cov qog hauv excretory, cov hlab ntsha thiab li qub, thiab lwm yam. qia hlwb. Hauv cov txheej txheem txias thiab khov ntawm cov qauv tshuaj lom neeg, thaum lub sijhawm hloov pauv ntawm cov kua mus rau cov khoom, qee qhov cua sov yuav raug tso tawm thiab nws qhov kub yuav nce. Cov txheej txheem khov yam tsis muaj kev tswj xyuas qhov txias txias yuav ua rau kev tuag ntawm cov txheej txheem ntawm cov hlwb. Lub ntsiab tseem ceeb los txhim kho cov ciaj sia taus ntawm cov qauv khov yog kom raug txiav txim siab txog theem hloov pauv ntawm cov qauv lom neeg thiab siv microcomputer kom txias pace kom nce cov kua nitrogen tawm thaum lub sij hawm hloov pauv, txhawm rau txhawm rau txhawm rau nce qhov kub thiab txias. theem hloov cov qauv thiab ua kom cov hlwb dhau theem hloov ntsiag to thiab sai.
Tshuaj kho mob
Cov kua nitrogen yog siv dav hauv cov tub yees hauv cryosurgery. Nws yog cov tub yees uas tau tsim los txog tam sim no, thiab thaum koj txhaj rau hauv cov khoom siv kho mob cryogenic, nws ua zoo li lub scalpel, thiab koj tuaj yeem ua txhua yam kev phais. Cryotherapy yog ib qho kev kho mob uas siv qhov kub thiab txias kom tawg cov kab mob. Raws li qhov tshwm sim ntawm qhov kev hloov pauv ntawm qhov kub thiab txias ntawm lub xov tooj ntawm tes, siv lead ua tsim nyob rau hauv cov qauv saum npoo, kom lub cell dehydration, shrinkage, electrolytes thiab lwm yam kev hloov, kev khov kuj tuaj yeem ua rau cov ntshav ntws hauv zos qeeb, ntshav stasis lossis embolism tshwm sim los ntawm cell hypoxia tuag.
HL Cryogenic khoom
HL Cryogenic khoomuas tau tsim nyob rau hauv 1992 yog ib hom lag luam koom nrogHL Cryogenic Equipment Company Cryogenic Equipment Co., Ltd. HL Cryogenic Equipment tau cog lus rau kev tsim thiab tsim khoom ntawm High Vacuum Insulated Cryogenic Piping System thiab cov cuab yeej txhawb nqa kom tau raws li ntau yam kev xav tau ntawm cov neeg siv khoom. Lub Nqus Tsev Insulated Yeeb Nkab thiab Flexible Hose yog tsim nyob rau hauv lub tshuab nqus tsev siab thiab ntau txheej txheej multi-screen tshwj xeeb insulated cov ntaub ntawv, thiab dhau los ntawm cov txheej txheem nruj heev thiab kev kho lub tshuab nqus tsev siab, uas yog siv rau kev hloov cov kua oxygen, kua nitrogen. , kua argon, kua hydrogen, kua helium, liquefied ethylene gas LEG thiab liquefied natural gas LNG.
Cov khoom series ntawm lub tshuab nqus tsev vacuum, lub tshuab nqus tsev raj, lub tshuab nqus tsev hose thiab Theem Separator hauv HL Cryogenic Equipment Company, uas dhau los ntawm cov kev kho mob nruj heev, yog siv rau kev thauj cov kua oxygen, kua nitrogen, kua argon, kua hydrogen, kua. helium, LEG thiab LNG, thiab cov khoom lag luam no tau txais kev pabcuam rau cov khoom siv cryogenic (xws li lub tank cryogenic thiab dewar flasks thiab lwm yam) hauv kev lag luam ntawm electronics, superconductor, chips, MBE, chaw muag tshuaj, biobank / cellbank, khoom noj khoom haus & dej haus, automation los ua ke, thiab scientific. tshawb nrhiav lwm yam.
