Cov khoom siv ntawm txoj hlua siv txoj hlua txiav txim siab cov haujlwm uas tau muab los ntawm txoj siv hlua. Cov ntaub ntawv sib txawv muaj kev siv sib txawv. Qee qhov siv tawv tawv tuaj yeem tiv taus kub, qee qhov tiv taus xeb, thiab qee qhov tiv taus oxidation. Kuv tau txheeb tawm qee cov ntaub ntawv ntawm cov khoom siv ntawm txoj hlua siv rau koj siv. Kuv cia siab tias cov ntaub ntawv suav sau tuaj yeem kawm paub ntau ntxiv txog kev paub ntawm cov menyuam ntxaij rau cov neeg siv khoom tshiab thiab qub.
