Raws li cov khoom siv dav siv hauv kev ntim khoom thiab lwm daim teb, cov ntawv sib xyaw muaj ntau yam khoom siv tau.
Ua ntej tshaj plaws, sawv daim ntawv muaj zoo transparency. Qhov no tso cai rau cov neeg siv khoom kom pom meej meej txog cov khoom thiab sab hauv cov khoom thaum ntim khoom, ua kom muaj kev txaus nyiam ntawm cov khoom lag luam. Hauv kev lag luam xws li cov zaub mov thiab cov tshuaj pleev ib ce, cov pob tshab no pab tso thiab muag cov khoom.
Cov tawv thiab cuam tshuam tsis kam ntawm cov ntawv plooj yog tseem zoo heev. Nws tsis yooj yim mus tawg lossis deform, thiab tuaj yeem tiv thaiv cov khoom thaum mus cia khoom thaum muaj kev cia siab tias cov khoom lag luam tuaj txog ntawm cov neeg tau txais kev pabcuam thiab nyab xeeb. Seb nws yog thaum lub sijhawm thauj mus los lossis thaum muab tso cia thiab khaws cia, nws tuaj yeem muab kev tiv thaiv zoo rau cov khoom.
Nyob rau hauv cov nqe lus ntawm kev sib khi, cov ntawv sib xyaw ua ke ua tau zoo. Nws tuaj yeem tiv thaiv kev nkag mus ntawm cov tshuaj xws li oxygen thiab ya raws, muaj txuas ntxiv rau lub txee lub neej ntawm cov khoom lag luam thiab tswj cov khoom lag luam zoo. Qhov no yog qhov tshwj xeeb tshaj yog rau cov khoom lag luam xws li cov khoom noj thiab tshuaj uas yuav tsum muaj cov chaw cia siab.
Ib qho ntxiv, cov nqi tsim khoom ntawm cov ntawv sib tsoo yog qhov tsawg. Hauv kev sib tw loj, nws tuaj yeem tswj cov nqi thiab txhim kho cov txiaj ntsig kev lag luam ntawm kev lag luam thaum ua kom cov khoom lag luam zoo.
Txawm li cas los xij, plooj ntawv ntawv kuj muaj qee qhov kev txwv. Piv txwv li, nws yog ib qho yooj yim los ua kom muaj dej taus thiab tawg hauv cov dej ntev, muaj kev ntxhov siab tsis zoo, thiab muaj cov hnyav tsis kam thiab hnav tsis kam. Txawm li cas los xij, qhov no tsis cuam tshuam nws daim ntawv thov hauv ntau thaj teb. Hauv kev thov tiag tiag, kev lag luam tuaj yeem muab tag nrho cov kev ua si rau nws cov txiaj ntsig thiab zam nws cov kev xav tau raws li cov kev xav tau. Hauv ntej, nkag siab txog kev ua tau zoo ntawm cov ntawv luam tawm yuav pab cov lag luam zoo dua xaiv thiab siv cov khoom no.
