Yog tias cov khoom siv crystalline raug txiav nrog cov khoom ntse, nws yuav ib txwm muab qhov chaw nrog cov npoo du thaum cov khoom amorphous yuav txiav rau hauv cov npoo nrog cov npoo tsis sib xws. Crystalline solids yog li ntawd hais tias muaj cleavage khoom, thiab amorphous solids tsis qhia cleavage khoom.
Vim li cas amorphous solids tsis qhia cov khoom tawg?
Cleavage dav hlau muaj nyob rau ntawm qhov kev txiav txim ntawm cov atoms yog li muab cov crystalline me me ntawm tib lub geometric kev npaj raws li niam txiv. Ntawm qhov tod tes, cov khoom sib xyaw ntawm cov khoom amorphous yog randomly teemthiab tsis qhia cov khoom tawg.
Dab tsi yog cov khoom tawg hauv amorphous solids?
Cleavage txhais tau tias txiav ib yam dab tsi hauv ob lossis ntau qhov tseem ceeb, yog li nws yog ib qho cuab yeej uas ua rau cov khib nyiab cuttable los yog tawg hauv cov khoom yooj yim. Ib crystalline khoom muab cov qauv zoo sib xws tom qab cleavage thaum lub amorphous solids tsis muaj. npaj qauv ces lawv muab irregular or insignificant pieces …
Yam khoom twg tsis pom los ntawm cov khoom amorphous?
Lawv yog tus yam ntxwv los ntawm lub koom haum crystalline tsis tu ncua ntawm atoms uas tau txiav txim siab ntev. Amorphous, lossis non-crystalline, cov khoom tsis muaj qhov kev txiav txim ntev ntev. Raws li, lawv tsis muaj elasticity, cov ntsiab lus melting txawv, thiab lwm yam khoom ntawm crystalline solids.
Amorphous khoom piv txwv yog dab tsi?
Ib qho khoom amorphous yog ib qho khoom uas tsis muaj kev txiav txim sab hauv. Piv txwv ntawm amorphous solids muaj xws li iav, roj hmab, thiab yas. Lub cev muaj zog ntawm amorphous solids txawv ntawm cov crystalline solids.
