Nyom,
Lub Koom Haum Ntxov Hauv Zej Zog
Ntim khoom thiab cov khoom siv dai,
Nws tau muaj nyob rau lub ntiaj teb rau ntau txhiab xyoo.
Thaum ntxov li 3700 BC,
Cov neeg Iyiv thaum ub ua iav ornaments
thiab yooj yim khob iav.
Niaj hnub nimno neeg,
Iav tseem txuas ntxiv txhawb kev nce qib ntawm tib neeg lub zej zog,
Los ntawm lub tsom iav raj ntawm tib neeg kev tshawb nrhiav ntawm qhov chaw
Optical Iav Lens Siv
mus rau fiber ntau iav siv hauv cov ntaub ntawv kis,
thiab lub teeb lub teeb tsim los ntawm Edison
Nqa lub teeb ci ci iav,
Txhua tus cuam tshuam txog lub luag haujlwm tseem ceeb ntawm cov ntaub ntawv iav.
Nyob rau hauv lub koom txoos niaj hnub no,
Iav yog ua ke
txhua qhov ntawm peb lub neej.
Nyob rau hauv cov kev tsoos txhua hnub noj teb,
Lub iav cov khoom coj kev ua tau zoo,
Nyob rau tib lub sijhawm, nws ntxiv kev zoo nkauj thiab txoj kev xav rau peb lub neej.
Hauv tshav pob ntawm cov neeg siv khoom lag luam entrators,
Txawb xov tooj, khoos phis tawj,
LCD TV, LED teeb pom kev zoo thiab lwm yam khoom siv hluav taws xob
Tsis muaj qhov xav tau rau cov khoom zoo ntawm cov khoom siv iav.
Nyob rau hauv daim teb ntawm cov kws ntim ntim,
Iav yog kom ze rau peb kev noj qab haus huv.
Hauv thaj chaw ntawm kev loj hlob tshiab,
Nws yog inseparable los ntawm kev pab ntawm cov khoom siv iav.
Photovoltaic iav los ntawm photovoltaics
kom tsim lub zog hluav taws xob txuag hluav taws xob
Raws li zoo li lub tsheb zaub iav thiab cov iav tsheb,
Cov Khoom Siv Cov Khoom Siv Hauv ntau cov subdivisions
muaj lub luag haujlwm irreplacable txoj haujlwm.
Thaum ntau tshaj 4,000 xyoo ntawm kev siv,
Iav thiab Tib Neeg Tib Neeg
Kev sib raug zoo sib txawv thiab kev sib raug zoo,
ua tau dav pom tau los ntawm cov pej xeem
Ntsuab, ib puag ncig phooj ywg thiab rov ua dua tshiab
Cov ntaub ntawv ib puag ncig ib puag ncig,
yuav luag tib neeg tib neeg
Txhua txoj kev txhim kho thiab kev nce qib,
Muaj cov khoom siv iav.
Cov khoom siv raw khoom ntawm iav yog ntsuab
Ntawm cov khoom sib txuas lus silacic uas suav tus qauv tseem ceeb ntawm cov iav, silicon yog ib qho ntawm cov muaj ntau heev hauv ntiaj teb, thiab silicon muaj nyob rau hauv daim ntawv ntawm cov zaub mov hauv xwm.
Cov ntaub ntawv raw siv hauv iav yog tsuas yog Quartz xuab zeb, Borax, Sorax, Serax, lime me me ntawm cov chaw tso quav
Cov ntaub ntawv raw no tsis zoo rau ib puag ncig thaum kev tiv thaiv kev tiv thaiv tau siv thaum siv.
Ntxiv mus, nrog rau kev txhim kho lub khob thev naus laus zis, kev xaiv ntawm cov khoom siv raw ua tsis muaj kev tiv thaiv kev nyab xeeb rau kev siv tshuaj tiv thaiv kev nyab xeeb kom ntseeg tau qhov ntsuab thiab noj qab haus huv Xwm ntawm iav raw khoom.
The production process of glass mainly consists of four steps: batching, melting, forming and annealing, and processing. Tag nrho cov txheej txheem ntau lawm tau ua tiav cov ntse tsim thiab kev tswj hwm.
Tus neeg teb xov tooj tuaj yeem teeb tsa tau thiab kho cov txheej txheem tsis muaj nyob hauv chav tswj hwm, uas tau siv txoj kev coj ua haujlwm tag nrho, uas tau txo qis kev siv haujlwm ua haujlwm thiab txhim kho kev ua haujlwm ntawm cov neeg ua haujlwm.
Thaum lub sij hawm ntau lawm cov iav, ib tus lej ntawm cov khoom zoo thiab emission soj ntsuam cov ntsiab lus tau ua kom cov iav ntau lawm ntsib cov qauv kev tiv thaiv hauv tebchaws.
Tam sim no, hauv cov txheej txheem ntau lawm ntawm cov iav, cov peev txheej tseem ceeb ntawm cov iav yaj yog cov khoom siv uas muaj zog los ntawm cov nkev roj thiab hluav taws xob.
Nrog rau kev txhim kho thiab kev nce qib ntawm cov iav ntau lawm tshuab, kev siv tshuab hluav taws xob ua kom zoo dua qub thiab kev siv hluav taws xob zoo thiab txuag hluav taws xob.
Txij li thaum cov txheej txheem sib txuas siv cov pa nrog lub ntsiab lus ntawm nitrogen oxides tsim los ntawm kev sib txuas hluav taws xob tau tsim los ntawm cov kev sib txuas yog kuj tau txais cov khoom siv cua sov thiab lub zog loj.
Nyob rau tib lub sijhawm, txhawm rau txo cov kuab paug paug, lub khob Hoobkas tau nqa tawm desulfurization, kev kho kom tsis kam lees thiab hmoov av tshem tawm cov roj flue.
Cov dej hauv cov iav kev lag luam yog tsuas yog siv rau ntau lawm txias, uas tuaj yeem pom tau tias cov dej rov ua dua. Vim tias cov iav yog qhov tsis muaj zog, nws yuav tsis ua rau cov dej txias, thiab lub khob iav muaj cov txheej txheem kev ywj pheej yuav tsis tsim cov dej khib nyiab.
