Homogeneous nucleation (tsis muaj kev cuam tshuam ntawm cov khoom txawv teb chaws) tshwm sim zoo hauv qab qhov chaw khov, ntawm qhov kub thiab txias uas tsis tau pom hauv dej. Qhov kub ntawm heterogeneous nucleation (nucleation pib ntawm qhov chaw ntawm cov khoom txawv teb chaws) nyob ntawm qhov xwm ntawm cov khoom, tab sis nws…
homogeneous nucleation nyob qhov twg?
3.1.
Hauv kev xyaum, homogeneous nucleation tsis tshua muaj tshwm sim thiab heterogeneous nucleation tshwm sim ntawm cov phab ntsa pwm lossis ntawm cov khoom tsis huv tsis huv.
Vim li cas heterogeneous nucleation tshwm sim?
Heterogeneous nucleation forms ntawm qhov chaw nyiam xws li theem ciam teb, qhov chaw (ntawm lub thawv, lub raj mis, thiab lwm yam) lossis impurities xws li hmoov av. Ntawm qhov chaw zoo li no, qhov zoo ntawm lub zog saum npoo yog qis dua, yog li txo qis lub zog tsis pub dawb thiab ua kom yooj yim nucleation.
Vim li cas heterogeneous nucleation feem ntau pom nyob rau hauv qhov?
Nyob rau hauv kev xyaum heterogeneous nucleation tshwm sim ntau dua li homogeneous nucleation. … Vim lub zog saum npoo qis, lub zog pub dawb txwv tsis pub txo thiab ua kom yooj yim nucleation ntawm cov chaw nyiam no. Qhov chaw muaj kev sib cuag ntawm cov theem siab tshaj xoom txhawb cov khoom rau nucleate.
Dab tsi yog homogeneous thiab heterogeneous nucleation?
Qhov sib txawv tseem ceeb ntawm homogeneous thiab heterogeneousnucleation yog tias homogeneous nucleation tshwm sim deb ntawm qhov chaw ntawm lub cev whereas lub heterogeneous nucleation tshwm sim ntawm qhov chaw ntawm lub system. … Yog li ntawd, cov khoom ncua kev kawm ntawv, cov npuas los yog qhov chaw ntawm lub cev tuaj yeem ua raws li qhov chaw nucleation.
