Txoj kev tiv thaiv kev tawg ntawm cov qhov rooj ntoo

1. Ua ntej, muaj ib qho kev teeb tsa, tso cai rau cov dej nag ncaj qha rau ntawm qhov rooj;
2. Kev nthuav dav thiab kev cog lus ntawm lub qhov rooj vaj huam sib luag tsis yog tsuas yog cuam tshuam los ntawm ib puag ncig ntuj, tab sis kuj muaj feem cuam tshuam rau qib ntawm deformation ntawm cov khoom nws tus kheej;
3. Cov khoom siv nrog me me deformation tuaj yeem siv tau, thiab cov dej noo ntawm cov ntaub ntawv tuaj yeem tswj tau zoo;
4. Raws li kev nyab xeeb hauv cheeb tsam, cov ntoo siv los tsim cov nplooj nplooj yuav tsum tau qhuav thiab tso cai kom rov qab ya raws tsawg kawg ib lub lis piam, muab cov khoom siv rau lub sijhawm kho kom txaus kom ruaj khov nws cov dej noo nyob ib ncig ntawm 12% ua ntej pib. txheej txheem txiav.
5. Tsis tas li ntawd, cov dej noo ntawm cov ntaub ntawv thaum lub sij hawm tsim khoom yuav tsum tau tswj kom zoo. Los ntawm kev txiav mus rau semi-tiav khoom kom txog rau thaum tha xim, nws yog ib qho tsim nyog los xyuas kom meej tias cov khoom tsis nqus noo noo thiab cov ntsiab lus noo noo tsis nce. Qhov no yuav tsum tau muab cov ntaub ntawv muab tso rau hauv ib chav tsev kub tas li raws sijhawm kom tswj tau cov dej noo ntawm cov ntoo los ntawm kev nce.
6. Nyob rau hauv cov nqe lus ntawm ntau lawm technology, los ntawm kev siv sib txawv knot kev twb kev txuas lug, anti deformation nplaum strips yog ntxiv rau qhov tseem ceeb tshaj plaws deformable qhov chaw ntawm lub qhov rooj qauv kom txo tau deformation.
