Cov Lus Qhia Dav Dav Hlau
Hlau, Alloy ntawm Hlau thiab Carbon uas cov pa roj carbon cov ntsiab lus nce mus txog 2 feem pua (nrog cov khoom siv roj carbon ntau dua, cov khoom txhais tau tias yog cam khwb cia hlau). Los ntawm cov khoom siv dav tshaj plaws rau kev tsim lub ntiaj teb cov cuab yeej siv hluav taws xob thiab kev lag luam, nws yog siv los khi txhua yam los ntawm cov roj tank tuaj rau cov roj tankers. Tsis tas li ntawd, cov cuab yeej yuav tsum tau tsim thiab tsim cov khoom xws li kuj yog ua los ntawm cov hlau. Raws li kev qhia ntawm qhov tseem ceeb ntawm cov khoom siv no, ethe tseemc yog tus nqi ntawm nws cov khoom nyoos (hlau ore thiab seem), thiab nws cov khoom tsis sib xws ntau yam ntawm cov tshuab khoom siv.
