Qhov kev sib txawv no tso cai rau cov seem hollow kom ua tau raws li cov yam ntxwv ntawm cov khoom siv uas xav tau rau ntau yam haujlwm engineering. Cov duab geometric ntawm cov seem hollow feem ntau muaj kev zoo nkauj dua li cov seem khov, ua rau lawv haum rau cov haujlwm uas xav txog kev tsim qauv thiab kev zoo nkauj. Vim lawv siv cov ntaub ntawv zoo dua, cov seem hollow tuaj yeem txo cov khoom pov tseg, ua raws li cov kev coj ua zoo rau ib puag ncig.
Ntim:
1. Kev ntim khoom yog qhov tseem ceeb heev tshwj xeeb tshaj yog thaum xa khoom mus thoob ntiaj teb uas cov khoom xa tuaj dhau ntau txoj kev sib txawv kom mus txog qhov chaw kawg, yog li peb thiaj li txhawj xeeb txog kev ntim khoom.
2. Saky Steel ntim peb cov khoom ntau txoj kev raws li cov khoom. Peb ntim peb cov khoom ntau txoj kev, xws li,
