Ua kom muaj hluav taws xob zoo li qub nyob hauv kev cia cov khoom ntim
Muaj ob qho laj thawj rau hluav taws xob zoo li qub: Ib qho yog qhov laj thawj sab hauv, uas yog, hluav taws xob ua hluav taws xob ntawm qhov quav; qhov thib ob yog qhov laj thawj sab nraud, uas yog, kev sib nrig sib txhuam, dov, thiab cuam tshuam ntawm cov tshuaj yeeb dej caw. Ntau cov khoom lag luam muaj cov teeb meem sab hauv rau cov hluav taws xob zoo li qub. Tsis tas li ntawd, lawv tsis tuaj yeem sib cais los ntawm kev tuav, khaws, npog thiab lwm yam haujlwm hauv kev khaws cia, yog li kev sib txhuam, dov, thiab cuam tshuam yuav tshwm sim dhau los ntawm pob. Hauv kev tsim cov txheej txheem, cov pob yas ntawm cov khoom siv dav dav yog cov nquag hluav taws xob vim tias kev sib txhuam.
Cov phom sij ntawm cov hluav taws xob zoo li qub hauv kev cia cov khoom ntim:
Cov txuam nrog cov hluav taws xob muaj qhov hluav taws xob zoo nyob rau saum npoo ntawm ntim khoom yog cov nquag hluav taws xob zoo li qub. Nws cov kev phom sij yog qhov tseem ceeb hauv ob yam:
Ib qho ua rau muaj qhov tsis xwm yeem. Piv txwv li, thaum cov ntsiab lus ntawm lub pob yog cov khoom siv hluav taws xob, lawv cov vaim volatilized vapor thiab huab cua ncav cuag ib qho kev sib piv, los yog thaum cov hmoov av plua plav ncav cuag qee qhov kev nkag siab (piv txwv li, tawg tsis pub tshaj), nws yuav tawg tau thaum nws ntsib hluav taws xob hluav taws xob.
Qhov thib ob yog hluav taws xob sib tsoo. Piv txwv, qhov muaj peev xwm ntau ntawm cov hluav taws xob zoo li qub tau tsim tawm thaum lub sij hawm tuav, uas yuav coj qhov tsis xis nyob ntawm hluav taws xob rau tus neeg teb xov tooj, uas feem ntau tshwm sim thaum lub tsev rau khoom tau tuav cov khoom ntim yas. Hauv cov txheej txheem ntawm kev tuav thiab txheej txheem, qhov zoo ntawm lub tshuab hluav taws xob tso tawm hluav taws xob tau tsim vim qhov kev sib txhuam muaj zog, thiab txawm tias qhov tshwm sim ntawm cov neeg ua haujlwm raug tua tawm los ntawm electrostatic paug tshwm sim.
