Kev Tshawb Xyuas Txog Kev Npaj Ntawm Lub Tshuab nqus tsev khov khov
Lub tshuab nqus tsev khov khov yog qhov txheej txheem kom qhuav. Nyob rau hauv cov mob qhuav, cov khoom qhuav tuaj yeem khaws cia rau lub sijhawm ntev yam tsis muaj qhov xav tau ntxiv rau ntawm qhov kub. Cov qauv tsim ntawm khov-qhuav khoom yog qhov ntxeem tau thiab nkig, thiab lub cev dej kom nrawm nrawm thaum siv. Cov xim, tshuaj tsw qab, saj, cov duab thiab cov kev ua ntawm cov ntawv tom qab lub cev dej tsis txaus hloov pauv. Lub tshuab nqus tsev khov khov yog tshwj xeeb tshaj yog tsim rau cov khoom noj, cov khoom kho mob thiab kev lag luam tshuaj. Lub tshuab nqus tsev tshuab kom khov yog kom khov cov khoom ntub lossis kev daws teeb meem rau lub xeev khov ntawm qhov kub tsawg dua (-10 ° C ~ -50 ° C), thiab tom qab ntawd ncaj qha sublime cov dej hauv qhov nqus (1.3 ~ 13 Pa) tsis muaj kua. Lub xeev gaseous, cov txheej txheem ziab uas thaum kawg lub cev qhuav dej. Kev thev naus laus zis yog qhov tseem ceeb tshaj tawm rau kev txhim kho kev lag luam thiab kev hloov pauv, thiab qhov zoo kuj yog qhov lav ntawm cov khoom lag luam. Nqus plua plav khov tshuab chaw tsim tshuaj paus ib txwm ua raws li" kev ua kom zoo ntawm kev muaj sia, kev ua haujlwm thiab kev txhim kho" cov laj thawj lag luam, twv kom yog thawj zaug, ua siab loj tsim kho, thiab siv zog txhim kho khoom kom zoo, yog li ua tau zoo tshaj rau peb cov neeg siv khoom.
Thaum siv lub tshuab nqus tsev ua lub tshuab cua txias thawj zaug, txhua feem ntawm lub ntsuas yuav tsum tau muab ntxuav kom huv. Cov tog hlau stainless tau ntxuav nrog ethanol thiab lub plexiglass yog ntxuav nrog saline li qub. Cov ampoule tau ntxuav nrog tus ultrasonic huv.
Kev tso khov ua ntej yuav tsum tau nqa ua ntej khov thiab ziab. Nws yog ib qho tsim nyog yuav tau npaj lub taub txias txias, qhov kub tsis txias txog 40 degrees Celsius, lossis ntsuas kub tsis txias txias ntawm kev rho tawm 80 degrees Celsius. Nws siv sijhawm li plaub teev los tso cov khoom kom qhuav hauv lub tub yees txias lossis kua nitrogen. Nws tuaj yeem pom ncaj qha rau sab nraud, tom qab tsab xov xwm tag nrho khov rau hauv dej khov, qhov kev sim khov-qhuav tuaj yeem nqa tawm, thiab cov khoom tau nrawm mus rau hauv lub tshuab nqus tsev khov lub tshuab ua kom lub khov kom zoo.
