Cov ntsiab lus ntawm glassy lub xeev
Lub xeev iav tsis yog lub xeev ntawm teeb meem, tab sis nws cov qauv. Cov khoom sib cais tau muab faib ua crystalline thiab amorphous. Cov atoms (los yog ions lossis molecules) uas ua kom cov kua siv lead ua muaj qee qhov sib faib qauv (piv txwv li cov ntxaij ntoo). Cov kua siv lead ua muaj qee yam siv lead ua duab thiab lub qhov chaw ruaj ruaj, thiab tsis muaj isotropy. Lub xeev glassy yog lub xeev amorphous. Lub xeev amorphous yog cov khoom uas tsis yog qhov siv lead ua. Nws tsis muaj qhov hloov cov duab thiab qhov chaw tas li melting, thiab isotropic. Lawv maj mam muag nrog kub nce ntxiv ua ntej thaum kawg yaj tas. Tom qab nws muag muag, nws tuaj yeem ua tiav rau hauv ntau daim duab
