Cov nqi Adhesion

Adhesion tus nqi: pes tsawg tus molecules adsorbed nyob rau hauv lub sij hawm nyob rau hauv lub sij hawm excection {} {}} migration: tus Kev txav ntawm cov lwg me me ntawm ib qho chaw saum npoo . 56. desorption: qhov tshwm sim ntawm kev tso roj lossis vapors adsorbed los ntawm cov ntaub ntawv. Kev tso tawm tuaj yeem yog ntuj los yog nrawm nrawm ntawm cov roj los ntawm cov roj av (lossis cov khoom siv roj av (lossis siv roj av) los ntawm cov khoom siv nyob rau hauv lub sijhawm so, divided by that time and that surface area. 60. Evaporation rate: The number of molecules (or mass of substance or mass of substance) evaporated from a surface within a given time interval divided by that time and the area of ​​that surface. 61. Permeation: The phenomenon of gas passing through a solid barrier layer. Qhov kev tshwm sim no suav nrog cov roj los ntawm cov khib nyiab thiab tuaj yeem suav nrog cov txheej txheem thaiv (qhov ntau ntawm cov pa hluav taws xob: raws li cov khoom siv ruaj khov ntawm ob sab ntawm cov txheej barrier. Daim ntawv ntawm txoj haujlwm no yog nyob ntawm lub cev cov txheej txheem koom nrog kev sib koom tes zoo: Cov khoom lag luam ntawm cov txheej txheem faib ua ke los ntawm thaj chaw nto
