Khoom Taw qhia
HOM T (Copper vs Constantan)yog siv los yog kev pab cuam nyob rau hauv oxidizing, inert los yog txo cua sov los yog nyob rau hauv lub nqus tsev vacuum. Nws yog heev resistant rau corrosion los ntawm atmospheric noo noo thiab condensation thiab exhibits siab stability ntawm tsawg kub. Nws yog tib hom uas muaj kev txwv ntawm kev ua yuam kev lav rau qhov kub thiab txias.
