Qhov no tsis yog ib qho kev xav tau cua sov. Finnish tus neeg siv khoom ib puag ncig kuaj chamber simulates polar climates, nrog qhov tsawg kawg nkaus sab hauv kub mus txog -65℃. Lawv yuav tsum tau nce qhov kub thiab txias ntawm cov chaw tshwj xeeb hauv chav rau -20℃lossis siab dua thaum qee qhov kev xeem, yuav tsum muaj cov cua sov uas tuaj yeem pib thiab ua haujlwm hauv qhov txias txias. Pa roj carbon monoxide rhaub tsim tau ntsib ntau yam teeb meem ntawm no: ua ntej, nce brittleness ntawm cov hlau raj thiab ua rau qis kub; thib ob, thermal stress los ntawm qhov kub thiab txias sib txawv (tej zaum tshaj 200 degree); thib peb, kev ua tau zoo hloov ntawm cov ntaub ntawv rwb thaiv tsev nyob rau hauv ib puag ncig uas tsis kub. Peb pawg kws tshaj lij tau soj ntsuam ntau qhov kev daws teeb meem: txiav txim siab tshwj xeeb stainless hlau nrog zoo dua qhov kub thiab txias toughness; optimizing cov mis thiab sau cov txheej txheem ntawm magnesium oxide hmoov los txhim kho thermal conductivity ntawm qhov kub thiab txias; tsim tshwj xeeb tsis cov qauv kom nqus tau cov thermal expansion stress. Tam sim no, kev xaiv cov khoom siv ua ntej tiav, thiab cov lus qhia ntxaws ntxaws thiab cov lus hais yuav raug xa mus rau tus neeg siv khoom lub lim tiam tom ntej. Qhov no yog lwm kauj ruam rau pem hauv ntej rau peb cov khoom mus rau hauv lub cheeb tsam ntawm huab ib puag ncig daim ntaub ntawv.
