Txiv hmab txiv ntoo thiab zaub tuaj yeem tshwj tseg nrog kev sib tw zoo thaum tseem tswj hwm lawv cov qauv ntawm cov kab mob khov {{}}}}}}}}}}}}}}}}}}}}}}}}}} qhuav. Thawj kauj ruam ntawm cov txheej txheem yog xaiv hwm tus nqi, freshly sau qoob loo thiab zaub uas yog nyob ntawm lawv tus cwj pwm. Los ntawm kev ua qhov no, qhov kawg khov -}} Cov khoom qhuav yog lav tau cov tsw zoo thiab muaj txiaj ntsig zoo. Tom qab raug xaiv, cov khoom lag luam yog ntxuav kom zoo kom tau tshem ntawm ib qho av, tshuaj tua kab, lossis lwm yam tsis txaus ntseeg. Txhawm rau kom khov thiab ziab, txiv hmab txiv ntoo thiab zaub yog feem ntau hlais rau hauv cov khoom sib thooj tom qab tu. Nyob ntawm cov hom tsim thiab siv cov khoom tiav tiav, cov ntawv no tuaj yeem sib txawv ntawm qhov loj me.
Tom qab hais tias, cov tsim khoom tsim tawm yog muab los ntawm kev tseem ceeb thawj theem ntawm khov -}}}}} qhuav txheej txheem: khov. Tsim tau khov khov khov, feem ntau rau ib tug kub ntawm -40 rau -50 degrees Celsius. Qhov kev pab khov kho no sai sai ntawm kev tsim cov roj khov dej khov nab kuab, uas tsis tshua muaj kev phom sij rau cov txiv hmab txiv ntoo 'thiab zaub' cellular. Cov kev ntxhib los mos ntawm cov khoom tsim tau zoo dua qub tau txais ob qho tib si thaum lub sij hawm thiab tom qab lub txheej txheem ziab khaub ncaws los ntawm kev ncaj ncees ntawm lub hlwb.
Tom qab cov khoom tsim tau solidified rau hauv dej khov, nws muab tso rau hauv lub nqus nqus tsev nrog lub siab tsis tshua muaj siab. Qhov ntsuas kub tau nce zuj zus nyob rau hauv no tsawg {1} pa ib puag ncig los pib sublimation, uas yog tus txheej txheem uas los ntawm cov dej khov uas tsis ua ntej dhau los ntawm cov theem ua kua. Lub khov tsim cov ntsiab lus dej feem ntau tau tshem tawm thaum lub sijhawm no, uas tau raug xa mus ua ntej kom qhuav. Vim tias lub tshuab nqus tsev txo cov dej npau npau, sublimation tuaj yeem tshwm sim ntawm qhov kub tsawg, uas ua rau nws tseem ceeb. Cov kabmob no hauv kev tswj cov khoom noj thiab hloov maj mam tsw qab uas yuav ploj ntawm qhov kub siab dua.
Cov khoom tsim tawm cov dej khov sublimates thaum thawj zaug ziab, thiab dej vapor txuas ntxiv mus ntawm lub tshuab nqus tsev. Nyob ntawm cov hom thiab ntim khoom noj tau qhuav, cov kauj ruam no yuav siv sijhawm ntau teev ua tiav. Txhawm rau kom tau txais kev ua kom qhuav, cov khoom lag luam yog nquag npaj hauv cov khaubncaws sab hauv cov tais hauv lub tshuab nqus tsev.
Cov khoom lag luam khaws cia cov kab qis ntawm cov chaw noo noo uas yog cov tshuaj lom neeg uas yog cov lwg me ntsis txawm tias tom qab thawj zaug ziab theem. Lub hom phiaj ntawm cov txheej txheem ua kom qhuav yog kom tshem ntawm qhov no noo noo. Nyob rau theem no, lub tshuab nqus tsev tau tswj xyuas thaum qhov ntsuas kub tau tsa me ntsis ntxiv. Cov dej noo noo yog ua tiav qis dua qib qis, feem ntau yog ntawm 1% thiab 4%, ua tsaug rau cov cua sov ntxiv uas pab yaj cov neeg sib tsoo tshuaj uas tuav dej lwg me. Los ntawm kev ua tiav cov khoom tiav tau ruaj khov thoob plaws hauv theem nrab qhuav, nws lub txee lub neej tau nce thiab nws yuav tsis muaj kev cuam tshuam rau kev piam sij.
Cov khoom lag luam yog maj mam coj rov qab mus rau cov atmospheric siab thaum lub tshuab ziab khaub ncaws tiav thiab lub tshuab nqus tsev tau raug tshem tawm. Tom ntej no, cov txiv hmab txiv ntoo thiab zaub uas tau khov -}} qhuav yog maj mam muab tawm ntawm lub chamber. Cov khoom no yog lub teeb heev, thiab ntxiv dej yog ib txoj kev yooj yim rau kev kub siab rau lawv.
