Qhov pom kev ntawm txoj kev tsheb ciav hlau yog hais txog qhov pom ntawm cov xim. Yog hais tias nws yog ib qho yooj yim mus nrhiav tau thiab pom, nws muaj siab visibility. Txhawm rau ua kom pom kev pom ntawm cov paib tsheb thaum hmo ntuj,iav hlawsyog tov rau hauv cov xim los yog kis tau rau saum npoo ntawm txheej thaum kos cov xim pleev xim, uas tuaj yeem cuam tshuam lub teeb lub tsheb rov qab rau tus neeg tsav tsheb lub qhov muag, yog li txhim kho qhov pom ntawm cov xim kos duab.
iav hlaws daiyog cov xim tsis muaj xim, pob tshab uas muaj lub luag haujlwm ntawm refraction, tsom thiab kev taw qhia ntawm lub teeb. Nws qhov sib ntxiv tuaj yeem txhim kho qhov ci ntsa iab thiab kav ntev ntawm cov xim pleev xim rau lub hauv paus ntawm kev txhim kho visibility.
Kev xav tau rauiav hlaws
iav hlaws daiyuav tsum tsis muaj xim thiab pob tshab spheres uas muaj lub luag haujlwm ntawm refraction, tsom thiab kev taw qhia ntawm lub teeb; lub roundness yuav tsum siab; yuav tsum muaj ob peb impurities, cov hais yuav tsum sib xws, thiab yuav tsum tsis txhob muaj iav hmoov ntau dhau. Covtxoj kev npavcov neeg tsim khoom pleev xim tau qhia tias qhov kev xav ntawm cov xim pleev xim los ntawm coviav hlawspre-mixed nyob rau hauv cov xim thiab coviav hlawskis tau rau saum npoo ntawm txheej. Yog hais tias lub roundness thiab refractive index ntawm lubiav hlawsyog siab thiab particle loj tis yog tsim nyog, lub reflective nyhuv ntawm cov xim xim yuav zoo. Lub particle loj ntawm lubiav hlawsyog matched nyob rau hauv ib tug tej yam kev faib ua feem kom paub meej tias coviav hlawshauvtxoj kev npavxim txheej adhere. Thaum siv,iav hlawsntawm qhov sib txawv qhov ntau thiab tsawg yog raug thiab poob tawm nyob rau hauv lem raws li lubtxoj kev npavpleev xim rau, kom covtxoj kev npavxim tuaj yeem txuas ntxiv kom pom lub teeb.
Pebtxoj kev npav tshuabtau muab faib ua peb hom raws li cov txheej txheem sib txawv: kub yaj kos tshuab, tshuaj tsuag txias tshuab, thiab ob lub ntsiab lus cim tshuab kom tau raws li koj cov kev xav tau sib txawv.
