Hmo pom kev pom ntawm txoj kev npav feem ntau yog nyob ntawm qhov kev rov qab los, uas cuam tshuam ncaj qha rau kev nyab xeeb ntawm tsheb. Reflective kev ua tau zoo tsis yog txiav txim los ntawm ib qho, tab sis los ntawm cov khoom siv, kev tsim kho, thiab ib puag ncig.
Ua ntej, txheej zoo muab lub hauv paus rau kev xav. Huab cua-tiv taus thiab siab- adhesion txheej tuav cov iav hlaws tsis tu ncua. Tsis zoo-cov khoom zoo tau yooj yim chalks thiab tawg, ua rau poob sai sai.
Qhov thib ob, iav hlaws yog lub hauv paus ntawm kev xav. Cov hlaws nrog siab refractive index, roundness, thiab uniform loj xa zoo dua reflectivity. Cov qauv zoo tagnrho yog ib nrab -embedded, ib nrab- nthuav tawm rau kev ua haujlwm zoo.
Kev tsim kho tseem ceeb sib npaug. Lub pavement yuav tsum huv si thiab qhuav; txwv tsis pub, adhesion yuav ua tsis tau. Daim ntawv thov kub, thickness, thiab hlaws hlaws txhua lub sij hawm cuam tshuam qhov sib xws thiab kav ntev.
Ib puag ncig thiab kev siv tsheb tsis tuaj yeem raug ignored. Hnub ci, nag, thiab roj npog hlaws dai; hnyav tsheb accelerates hlaws poob. Siab - txoj kev ntim ntau yuav tsum tau hnav ntau dua - cov ntaub ntawv pov thawj.
Nyob rau hauv luv luv, siab - cov cim kev zoo cia siab rau cov ntaub ntawv zoo, kev tsim qauv, thiab kev saib xyuas kom zoo kom ua tiav ntev - kav ntev, ruaj khov, thiab pom tseeb hmo ntuj.
