Cov yam ntxwv ntawm electron nqaj evaporation txheej
Apr 26, 2020| Cov yam ntxwv ntawm electron nqaj evaporation txheej
Lub tshuab hluav taws xob nqaj hlau txheej txheej tshuab yog ib hom ntawm cov khoom tsim zaj duab xis uas feem ntau siv hauv kev lag luam. Vim yog cov yam ntxwv ntawm lub tshuab evaporation txheej, nws ua lub luag haujlwm tseem ceeb hauv kev tsim cov yeeb yaj kiab. Cov cim ntawm cov yeeb yaj kiab tsuas yog tsim los ntawm cov cua kub ntawm electron nqaj hauv lub tshuab txheej. 1, qhov zoo ntawm electron nqaj cua sov evaporation txheej txheej txheej qauv ntawm electron nqaj cua sov hauv lub tshuab txheej piv nrog cov txheej txheem ib txwm ntawm kev ua haujlwm cua sov. Cov. Cov hluav taws xob nqaj cua sov ua rau muaj qhov cuam tshuam ntau dua ntom ntom, uas zoo rau evaporation ntawm cov ntaub ntawv nrog lub ntsiab lus siab melting, thiab tseem tuaj yeem txhim kho tus nqi ntawm evaporation rau qee yam. (2) evaporation txheej tshuab nyob rau hauv kev ua haujlwm ntawm qhov yuav tsum tau vaporized raw cov ntaub ntawv rau hauv tooj liab crucible, kom cov khoom tuaj yeem tuaj yeem lav kom tsis txhob muaj kuab paug, tuaj yeem tsim kom muaj qhov siab dua ntawm zaj duab xis. Lub e - nqaj evaporation ntawm lub zog kev tig kis lub zog yog qhov loj me, yog li yuav muaj txiaj ntsig zoo rau zaj duab xis precision thiab khi quab yuam. 2, hluav taws xob nqaj hluav taws xob cua sov evaporation txheej tsis zoo rau cov qauv tag nrho ntawm electron nqaj evaporation txheej tshuab ua ntau dua, tus nqi piv nrog lwm cov khoom siv txheej txheej yog qhov siab dua. Thaum lub tshuab txheej ua haujlwm, yog tias qhov ceev ntawm cov pa taws nyob ze qhov chaw evaporation yog qhov siab, nws yuav ua rau qee qhov cuam tshuam ntawm lub nqaj hlau hluav taws xob thiab cov nplaim hluav taws xob, yuav muaj kev cuam tshuam rau qhov hluav taws xob flux, ua rau hluav taws xob flux ploj lossis offset lub teb. Nyob rau tib lub sijhawm, koj tuaj yeem ua rau kom muaj siab thiab ionization ntawm cov pa thiab cov roj av, uas cuam tshuam rau qhov zoo ntawm tag nrho zaj duab xis.
