Qhov yooj yim tshaj plaws qhov sib txawv ntawm crystalline khoom thiab noncrystalline Solids (NCS) yog qhov kev txiav txim ntev ntev hauv Kev faib tawm ntawm atoms (ions) lossis molecules tshwm sim hauv thawj rooj plaub tab sis tsis yog hauv thib ob.

Nyob rau hauv no txoj kev, dab tsi yog ib tug non crystalline qauv?

Nyob rau hauv condensed teeb meem physics thiab cov ntaub ntawv science, ib tug amorphous (los ntawm Greek a, tsis muaj, morphé, shape, form) los yog tsis yog - crystalline khoom yog ib qho khoom uas tsis muaj qhov kev txiav txim ntev ntev uas yog tus yam ntxwv ntawm cov siv lead ua. Hauv qee phau ntawv qub, lo lus tau siv los ua ke nrog iav.

Ib tug kuj yuav nug, dab tsi yog qhov txawv ntawm crystal thiab crystalline? 1. " Crystal ” yog ib lub npe uas hais txog lub pob zeb uas muaj cov atoms tsim hauv a rov ua yam uas txuas mus rau txhua qhov spatial. 2. " Crystalline ” yog ib qho adjective uas piav txog cov pob zeb uas muaj cov khoom lossis cov khoom zoo siv lead ua.

Tsis tas li ntawd, qhov txawv ntawm cov crystalline thiab cov khoom amorphous yog dab tsi?

Qauv ntawm Crystalline thiab Amorphous Crystalline Cov khib nyiab muaj cov duab meej nrog cov txheej txheem ions, molecules lossis atoms hauv a peb-dimensional qauv feem ntau termed siv lead ua daim kab xev. Amorphous Cov khib nyiab, ntawm qhov tod tes, muaj qhov tsis sib haum xeeb ntawm cov khoom tsis pom qhov tseeb.

Puas yog ntoo crystalline lossis amorphous?

Crystalline cov khoom muaj xws li pob zeb, ntoo , ntawv thiab paj rwb. Cov khib nyiab no yog tsim los ntawm cov atoms uas tau teem rau hauv cov qauv tseeb. Thaum twg crystalline Cov khib nyiab yog rhuab, hloov mus rau cov kua, hu ua melting, yog ntse thiab meej. Amorphous cov khoom muaj xws li roj hmab, iav thiab sulfur.
