Niaj hnub no kev tsim khoom lag luam niaj hnub no, cov ntawv sau ua tau dav hauv kev ua lag luam, yuav ua li cas xaiv cov khoom siv hluav taws xob tau ua qhov tseem ceeb ntawm ntau cov tuam txhab thiab cov neeg siv khoom.
Kev ua yeeb yam ntawm cov khoom yog thawj daim ntawv txheeb xyuas thaum xaiv cov ntawv qhia txog lub cev, thiab tshuaj lom neeg muaj zog, thiab tshuaj lom neeg muaj peev xwm ua kom muaj kev ruaj khov ua haujlwm tau kub kub .
Ntxiv rau kev ua tau zoo, kev ua haujlwm tseem ceeb ntawm kev tsim cov nqi polymer muaj cov nqi tsim khoom ntawm cov khoom lag luam polymer muaj li cov khoom siv polymer Txhawm rau txiav txim siab raws li lawv cov kev ua tau zoo ua tau raws cov khoom lag luam xav tau .
Qhov ntsuas ib puag ncig tseem yog qhov ntsuas tseem ceeb uas yuav tsum tau them rau cov khoom lag luam polymer, thiab cov neeg siv khoom tsis zoo, thiab cov neeg muaj kuab lom lub cev .
Tsis tas li ntawd, kev raug nqi-txiaj ntsig tseem yog ib qho ntawm cov ntaub ntawv sib txawv ntawm lawv tus kheej cov kev xav tau thiab cov peev txheej {4 4}}
Hauv cov ntsiab lus xaus, thaum xaiv cov ntawv txheeb polymer, ntau yam xws li kev ua tau zoo, thiab tus nqi ua haujlwm tau zoo rau lawv cov kev xav tau los pab cov tuam txhab kev ua lag luam tawm hauv kev ua lag luam tawm hauv kev ua lag luam ua lag luam ua lag luam
