- Rau cov khoom uas yooj yim oxidized, xaiv cov ntaub ntawv ntim khoom uas muaj cov yam ntxwv zoo tiv thaiv oxygen kom txo qhov cuam tshuam oxidative ntawm oxygen rau cov khoom.
- Rau cov khoom uas yooj yim cuam tshuam los ntawm cov spectrum, xaiv cov ntaub ntawv ntim khoom uas muaj cov khoom tiv thaiv UV los tiv thaiv kev ruaj khov thiab zoo ntawm cov khoom.
4. Cov ntaub ntawv ntim khoom ruaj khov thiab zoo rau ib puag ncig:
- Xav txog qhov ruaj khov ntawm cov ntaub ntawv ntim khoom thiab xaiv cov ntaub ntawv uas lwj tau lossis siv dua tshiab kom txo qhov cuam tshuam rau ib puag ncig.
- Nkag siab txog cov txheej txheem tsim khoom ntawm tus neeg muag khoom thiab cov kev ntsuas tiv thaiv ib puag ncig kom ntseeg tau tias kev tsim cov ntaub ntawv ntim khoom ua raws li cov qauv ib puag ncig thiab cov ntsiab cai kev txhim kho kom ruaj khov.
- Xav txog cov peev xwm rov ua dua tshiab ntawm cov ntaub ntawv ntim khoom, txhawb kom cov neeg siv rov ua dua tshiab thiab siv cov ntaub ntawv ntim khoom dua tshiab, thiab txo cov khib nyiab thiab kev siv cov peev txheej.
5. Kev ntseeg tau ntawm cov khoom ntim khoom siv:
- Soj ntsuam qhov kev ntseeg siab thiab kev tsim nyog ntawm cov neeg muab khoom kom ntseeg tau tias lawv muaj peev xwm muab khoom ruaj khov.
- Xav txog lub peev xwm tsim khoom ntawm tus neeg muag khoom, lub kaw lus tswj xyuas zoo, thiab tus nqi xa khoom raws sijhawm kom ntseeg tau tias kev tsim khoom thiab kev muab cov ntaub ntawv ntim khoom ua tau raws li koj xav tau.
6. Kev tsim cov ntim khoom thiab kev ua kom zoo nkauj:
- Xav txog qhov tsim ntawm cov ntaub ntawv ntim khoom kom paub tseeb tias nws phim qhov chaw thiab lub npe ntawm cov khoom.
- Xav txog qhov plasticity ntawm cov ntaub ntawv ntim khoom kom ua tau raws li cov duab khoom thiab qhov muaj peev xwm xav tau thaum tseem tswj hwm kev nqa mus los thiab yooj yim siv.
- Nkag siab txog kev luam ntawv thiab cim cov txheej txheem kom ntxiv cov ntaub ntawv tsim nyog ntawm cov khoom, cov ntawv lo lossis cov cim lag luam.
7. Kev siv nyiaj tsim nyog thiab kev ua haujlwm tau zoo ntawm cov ntaub ntawv ntim khoom:
