Kev sib xyaw xim yas yog ua raws li peb cov xim xim liab, daj thiab xiav, kom phim cov xim uas nrov, ua tau raws li cov xim sib txawv ntawm daim npav xim, yog kev lag luam, thiab tsis hloov xim thaum ua thiab siv.Tsis tas li ntawd, cov xim yas kuj tuaj yeem faib ua ntau yam haujlwm rau cov yas, xws li kev txhim kho lub teeb thiab huab cua tsis kam ntawm cov yas;muab cov yas qee yam tshwj xeeb, xws li hluav taws xob conductivity thiab antistatic zog;Cov xim sib txawv ua liaj ua teb mulch films muaj cov haujlwm ntawm cov nroj tsuag los yog kab tshuaj tua kab thiab kev cog qoob loo.Hais tias yog, nws kuj tuaj yeem ua tau raws li qee qhov kev thov los ntawm kev sib xyaw xim.
Vim hais tias cov xim yog rhiab heev rau cov yas ua cov txheej txheem, ib qho tseem ceeb ntawm cov txheej txheem yas yog txawv, xws li xaiv raw cov ntaub ntawv, toner, machinery, molding tsis thiab cov neeg ua hauj lwm, thiab lwm yam, yuav muaj xim txawv.Yog li ntawd, kev sib txuam xim yog ib txoj haujlwm zoo heev.Feem ntau, peb yuav tsum tau them sai sai rau cov ntsiab lus thiab tsub zuj zuj ntawm cov kev paub dhau los, thiab tom qab ntawd muab cov kev xav ntawm cov xim yas sib xyaw ua ke txhawm rau txhim kho cov xim sib xyaw kom sai.
Yog tias koj xav ua kom tiav cov xim sib txuam zoo, koj yuav tsum xub nkag siab lub hauv paus ntsiab lus ntawm cov xim xim thiab xim sib txuam, thiab raws li qhov no, koj tuaj yeem nkag siab tob txog kev paub txog kev sib txuam ntawm cov xim yas.
Thaum kawg ntawm lub xyoo pua 17th, Newton tau ua pov thawj tias xim tsis muaj nyob hauv cov khoom nws tus kheej, tab sis yog qhov tshwm sim ntawm kev ua ntawm lub teeb.Newton refracs tshav ntuj los ntawm ib tug prism thiab ces project nws ntawm ib tug dawb screen, uas yuav qhia ib tug zoo nkauj spectral xim band zoo li zaj sawv (xya xim liab, txiv kab ntxwv, daj, ntsuab, cyan, xiav, thiab ntshav).Lub teeb ntev thiab luv luv ntawm qhov pom spectrum ua ke los ua lub teeb dawb.
Yog li, xim yog ib feem ntawm lub teeb thiab yog tsim los ntawm electromagnetic nthwv dej ntawm ntau qhov ntev sib txawv.Thaum lub teeb nthwv dej tau npaj rau ntawm ib qho khoom, cov khoom xa tawm, nqus lossis cuam tshuam qhov sib txawv ntawm lub teeb nthwv dej.Thaum cov kev xav tsis thoob ntawm qhov ntev sib txawv txhawb tib neeg lub qhov muag, lawv yuav tsim cov xim sib txawv hauv tib neeg lub hlwb, thiab yog li xim tuaj.
Lub npe hu ua kev sib txuam xim yog tso siab rau lub hauv paus theoretical ntawm peb lub ntsiab xim, thiab siv cov tswv yim ntawm cov xim ntxiv, cov xim rho tawm, xim sib txuam, cov xim sib xyaw thiab cov xim achromatic los npaj cov xim uas xav tau los ntawm cov khoom.
