Cov pa roj nitrogen uas ua kua: Cov pa roj nitrogen nyob rau hauv lub xeev kua. Inert, tsis muaj xim, tsis muaj ntxhiab, tsis xeb, tsis kub hnyiab, kub heev cryogenic. Nitrogen tsim feem ntau ntawm huab cua (78.03% los ntawm qhov ntim thiab 75.5% los ntawm qhov hnyav). Nitrogen tsis ua haujlwm thiab tsis txhawb kev kub hnyiab. Frostbite tshwm sim los ntawm kev sib cuag endothermic ntau dhau thaum lub sijhawm ua pa.
Cov kua nitrogen yog ib qho chaw txias uas yooj yim siv. Vim nws cov yam ntxwv tshwj xeeb, cov kua nitrogen tau maj mam them sai sai thiab lees paub los ntawm tib neeg. Nws tau siv dav dua hauv kev yug tsiaj, kev lag luam kho mob, kev lag luam zaub mov, thiab kev tshawb fawb cryogenic. Hauv kev siv hluav taws xob, metallurgy, aerospace, kev tsim tshuab thiab lwm yam, daim ntawv thov tau nthuav dav thiab tsim kho.
Kev txawj sau cov kab mob me me hauv cov kua nitrogen cryogenic
Lub hauv paus ntsiab lus ntawm cov kua nitrogen tas mus li, uas sau cov kab mob ntawm -196 ℃, yog sau cov kab mob me me kom zoo los ntawm kev siv qhov zoo li yuav tiv thaiv kev ua haujlwm ntawm cov kab mob me me hauv qab -130 ℃. Macrofungi yog ib pawg tseem ceeb ntawm cov fungi (cov fungi uas tsim cov txiv hmab txiv ntoo loj hauv cov fungi, feem ntau xa mus rau nceb lossis nceb hauv lub ntsiab lus dav). Ntau hom tsiaj muaj cov nqi khoom noj khoom haus siab thiab cov nqi kho mob, thiab lawv muaj kev cia siab rau kev siv ntawm cov fungi. Tsis tas li ntawd, qee cov fungi loj tuaj yeem txheeb xyuas cov nroj tsuag tuag, uas ua lub luag haujlwm tseem ceeb hauv kev tswj hwm cov khoom siv ntuj thiab kev sib npaug ntawm ecological, thiab tuaj yeem tsim thiab siv rau kev lag luam ntawv thiab kev ntxuav ib puag ncig. Qee cov fungi loj tuaj yeem ua rau muaj kab mob ntoo lossis ua puas ntau yam khoom ntoo. Kev txhim kho ntawm kev nkag siab ntawm cov fungi pathogenic no yog qhov zoo rau kev tiv thaiv thiab tshem tawm kev puas tsuaj. Cov qauv sau ntawm macrofungi yog qhov tseem ceeb heev rau kev nyob ntsiag to thiab kev sau cov peev txheej microbial, kev sau cov peev txheej genetic tas mus li thiab muaj txiaj ntsig, thiab kev sib koom ntawm biodiversity hauv ntau qhov chaw sib txawv.
Kev ciaj sia ntawm cov tsiaj txhu hauv kev ua liaj ua teb
Shanghai tau nqis peev ntau dua 41 lab yuan los tsim thiab xa cov ntaub ntawv txog cov noob caj noob ces ua liaj ua teb hauv Suav teb. Kev lag luam noob, uas muaj peev xwm qhib kev lag luam thoob ntiaj teb, yuav siv lub txhab nyiaj noob caj noob ces ua qhov chaw ntawm cov ntaub ntawv yug me nyuam, kev lag luam ua liaj ua teb tau hais. Lub txhab nyiaj noob caj noob ces ua liaj ua teb Shanghai Agricultural Biological, nrog thaj tsam tag nrho ntawm 3,300 square meters, yuav nyob hauv Shanghai Academy of Agricultural Sciences. Nws yuav sau tsib hom kev pab cuam noob caj noob ces ua liaj ua teb suav nrog noob cog, cov ntaub ntawv cog sab nraud, cov hlwb yug me nyuam tsiaj, cov kab mob me me thiab cov ntaub ntawv tsim kho noob caj noob ces.
Tshuaj kho mob khaub thuas
Kev loj hlob sai ntawm cov tshuaj kho mob cryogenic tau txhawb nqa kev loj hlob ntawm kev hloov pauv tshuaj, tshwj xeeb tshaj yog hauv cov pob txha pob txha, cov hlwb hematopoietic, daim tawv nqaij, lub qhov muag, cov qog tso zis sab hauv, cov hlab ntsha thiab cov qhov dej, thiab lwm yam. Kev hloov pauv hlwb hematopoietic zoo nyob ntawm kev ciaj sia ntawm cov hlwb hematopoietic. Hauv cov txheej txheem txias thiab khov ntawm cov qauv tshuaj lom neeg, thaum lub sijhawm hloov pauv ntawm kua mus rau khoom, qee qhov cua sov yuav raug tso tawm thiab nws qhov kub yuav nce. Cov txheej txheem khov yam tsis tswj qhov txias yuav ua rau cov hlwb tsim tuag. Qhov tseem ceeb los txhim kho qhov ciaj sia ntawm cov qauv khov yog txiav txim siab qhov hloov pauv theem ntawm cov qauv tshuaj lom neeg thiab siv microcomputer los txias qhov nrawm kom nce qhov ntau ntawm cov kua nitrogen nkag thaum lub sijhawm hloov pauv theem, kom tswj qhov kub nce ntawm cov qauv tshuaj lom neeg thiab ua kom cov hlwb dhau qhov hloov pauv theem ntsiag to thiab sai.
Kev kho mob hauv tsev kho mob
Cov kua nitrogen yog ib yam khoom siv txias uas siv dav hauv kev phais mob cryosurgery. Nws yog ib yam khoom siv txias uas tau tsim los txog tam sim no, thiab thaum koj txhaj nws rau hauv lub cuab yeej kho mob cryogenic, nws ua haujlwm zoo li rab riam phais, thiab koj tuaj yeem ua txhua yam kev phais. Cryotherapy yog ib qho kev kho mob uas siv qhov kub cryogenic los rhuav tshem cov qauv mob. Vim yog qhov hloov pauv sai ntawm qhov kub ntawm lub cell, kev tsim cov siv lead ua hauv qhov chaw ntawm cov qauv, yog li ntawd lub cell qhuav dej, ntsws, electrolytes thiab lwm yam kev hloov pauv, kev khov kuj tseem tuaj yeem ua rau cov ntshav ntws qeeb, ntshav tsis txav lossis embolism ua rau lub cell hypoxia tuag.
Cov Khoom Siv Cryogenic HL
Cov Khoom Siv Cryogenic HLuas tau tsim muaj xyoo 1992 yog ib lub npe koom nrogHL Cryogenic Khoom Siv Tuam Txhab Cryogenic Equipment Co., Ltd. HL Cryogenic Equipment cog lus rau kev tsim thiab tsim cov High Vacuum Insulated Cryogenic Piping System thiab lwm yam khoom siv txhawb nqa kom tau raws li ntau yam kev xav tau ntawm cov neeg siv khoom.
