Spinodal decomposition tshwm sim thaum ib theem thermodynamic spontaneously cais ua ob theem. Decomposition tshwm sim thaum tsis muaj nucleation vim qee qhov kev hloov pauv hauv lub cev txo qis lub zog dawb. Raws li qhov tshwm sim, qhov hloov pauv theem tshwm sim tam sim.
Lub ntsiab lus ntawm spinodal yog dab tsi?
Spinodal lub ntsiab lus
(chemistry) Piav txog kev hloov pauv ntawm cov txheej txheem ntawm ob lossis ntau yam khoom hauv ib theem metastable rau hauv ob theem ruaj khov.
Dab tsi yog spinodal thiab Binodal?
Nyob rau hauv thermodynamics, lub binodal, tseem hu ua coexistence nkhaus los yog binodal nkhaus, qhia txog qhov xwm txheej ntawm ob theem sib txawv tuaj yeem ua ke. … Qhov kawg ntawm qhov nkhaus binodal nyob rau hauv qhov kub thiab txias coincides nrog ib tug ntawm cov spinodal nkhaus thiab paub tias yog ib qho tseem ceeb point.
thaj tsam ntawm spinodal decomposition yog dab tsi?
Nyob rau hauv daim duab qhia theem thaj tsam tsis ruaj khovyog txhais los ntawm spinodal. Thaum lub kaw lus tau hla qhov chaw no, theem kev sib cais tshwm sim spontaneously yam tsis muaj cov kauj ruam nucleation. Cov txheej txheem no yog hu ua spinodal decomposition thiab feem ntau ua rau muaj kev sib txuas siab ntawm ob theem.
Puas spinodal decomposition yuav tsum tau diffusion?
Spinodal decomposition koom nrog uphill diffusion whereas diffusion yog ib txwm cia li ib qho concentration gradient rau nucleation thiab loj hlob ntawm hom illus-trated nyob rau hauv daim duab.
