Cov khoom tuaj yeem yog dawb huv lossis tsis huv, muaj sia lossis tsis muaj sia. Cov ntaub ntawv tuaj yeem raug cais raws li lawv lub cev thiab tshuaj lom neeg, lossis ntawm lawv cov keeb kwm geological lossis kev ua haujlwm lom neeg.
Kev faib cov ntaub ntawv yog dab tsi?
Cov khoom siv tau yooj yim tau muab faib ua peb yam kev faib tawm: metals, ceramics, thiab polymers. Cov tswv yim no yog ua raws li cov tshuaj pleev ib ce thiab cov qauv atomic, thiab cov ntaub ntawv feem ntau poob rau hauv ib pawg los yog lwm qhov, txawm tias muaj qee qhov nruab nrab.
3 qhov kev faib khoom yog dab tsi?
Kev lig kev cai peb cov khoom tseem ceeb yog metals, polymers, thiab ceramics. Piv txwv ntawm cov no yog hlau, ntaub, thiab tais diav.
5 yam khoom siv yog dab tsi?
