Vim li cas thiaj muaj npuas ntawm cov ntsiab lus vuam ntawm qhov nruab nrab zaus qhov chaw vuam tshuab?Kev tsim cov npuas ua ntej yuav tsum tsim kom muaj cov tub ntxhais ua npuas, uas yuav tsum ua tau raws li ob qho xwm txheej: ib qho yog cov kua hlau muaj cov roj supersaturated, thiab lwm qhov yog tias nws muaj lub zog xav tau rau nucleation.Kev tshuaj xyuas thiab kev daws teeb meem ntawm cov npuas sib koom ua ke:
Lub supersaturation hauv cov kua hlau yog qhov siab, thiab qhov siab dua qhov supersaturation, qhov tsis ruaj tsis khov.Gas feem ntau yuav los nag thiab ua npuas.Yog li ntawd, lub pas dej molten hauv vuam muaj qhov tsim nyog supersaturation rau tsim npuas.Zoo li cov txheej txheem ntawm cov hlau crystallization, npuas nucleation tuaj yeem tshwm sim hauv ob txoj hauv kev: spontaneous nucleation thiab non spontaneous nucleation.Yog tias cov tub ntxhais ua npuas tsim, lub npuas yuav tsum kov yeej cov kua siab thiab ua haujlwm nthuav dav
Vim yog qhov nce ntawm lub zog saum npoo los ntawm kev tsim cov theem tshiab, yog tias cov tub ntxhais ua npuas nrog qhov loj me yog tsim hauv cov kua, lub zog txaus yuav tsum tau muab los tsim lub zog nuclear.Pom tseeb, qhov siab dua lub zog nucleation, qhov tsawg dua nws yog tsim kom muaj cov tub ntxhais ua npuas.Hloov pauv, qhov yooj yim dua nws yog tsim kom muaj cov tub ntxhais ua npuas.
