Rau lub raj mis iav nws tus kheej, nws cov khoom tseem ceeb yog silicon dioxide thiab ib qho me me ntawm sodium oxide, calcium oxide thiab lwm yam. Lub raj mis nws tus kheej tsis muaj cov tshuaj phem. Nyob rau tib lub sijhawm, iav fwj yog ib puag ncig thiab siv tau dua tshiab piv rau cov ntaub ntawv yas thiab cov khoom siv tshuaj. Nws tuaj yeem hais tias yog kev txhim kho loj hauv keeb kwm ntawm tib neeg lub teeb pom kev lag luam khoom siv thiab kev tsim muaj zoo. Cov iav fwj muaj ntau yam kev siv hauv peb lub neej. Lawv tuaj yeem siv los ua cov thawv ntim dej los pab txhawb peb lub neej, thiab lawv kuj tuaj yeem siv los ua cov khoom siv tes ua los kho kom zoo nkauj rau peb ib puag ncig. Qee tus phooj ywg tuaj yeem nug, vim tias cov iav fwj tsis muaj tshuaj lom thiab tsis muaj mob thiab yooj yim rau kev tsim khoom, vim li cas muaj kev rov qab tshwj xeeb ntawm cov fwj pov tseg? Dab tsi yog qhov tseem ceeb siv?
(1) Txuag cov peev txheej
Txawm hais tias iav tsis yog qhov khoom tseem ceeb rau nws, cov khoom xyaw tsim rau kev tsim tawm kuj yog cov khoom qub. Tab sis rov qab siv cov fwj qub tuaj yeem txuag lub zog rau ntau yam. Lub zog siv hluav taws xob tsis yog tsuas yog siv cov khoom nyoos rau ntawm qhov chaw xws li xuab zeb thiab silicon. Qhov hluav taws xob, thee, thiab dej tsim nyog rau kev tsim khoom tom qab nws kuj yog kev siv ntau. Raws li kev txheeb cais, nyob rau xyoo 2015, kuv lub teb chaws ib xyoos tsim tawm ntawm cov cawv txiv hmab thiab iav fwj tau txog 50 billion. Nws tuaj yeem xav tias yuav siv hluav taws xob thiab haus dej npaum li cas. Yog li nws yog qhov tsim nyog kom rov qab siv cov hwj.
(2) Txhim kho kev siv
Tom qab lub hwj tau rov ua dua, lub zog tuaj yeem txuag tau thiab qhov nyiaj khib nyiab tuaj yeem txo kom tsawg. Nyob rau tib lub sijhawm, lub khob iav rov qab tuaj yeem siv tau cov khoom siv raw khoom rau kev tsim cov khoom lag luam. Txij li cov iav fwj muaj ntau lub zog ua haujlwm tom qab siv dua, kuv cov txheeb cais pom tias kev rov ua dua tshiab ntawm cov fwj iav tuaj yeem ncav cuag 30%, thiab kwv yees li 3 billion lub khob fwj tau rov ua dua txhua xyoo.
(3) Txo cov khib nyiab kom tsawg
Rov qab siv cov hwj siv txo qis kom cov khib nyiab ntau ntxiv hauv cov chaw nyob deb nroog thiab hauv nroog, tuaj yeem tiv thaiv ib puag ncig hauv zos thiab txo cov kab mob loj hlob. Nws muaj cov txiaj ntsig zoo ntawm kev tiv thaiv ib puag ncig.
Tom qab nyeem cov lus saum toj no, koj puas paub lub ntsiab lus tseem ceeb ntawm kev rov ua dej khib nyiab? Muaj ntau ntau yam teeb meem kev sib raug zoo thiab nyiaj txiag muab zais tom qab lub raj mis me me. Yog li thov koj tsis txhob muab pov tseg rau hauv koj lub neej. Muab nws tso rau hauv cov thawv ntim khoom kuj yog ib qho yooj yim ntawm kev ua siab zoo.
