Kev khaws cov ntawv sau hlau thiab xa nws mus rau kev coj ua dua tshiab tsis tsuas yog cov xwm txheej thiab ib puag ncig, tab sis kuj tuaj yeem ua qhov nyiaj tau zoo heev. Txhua xyoo qhov ntau ntawm kev lees txais seem hlau yog loj hlob, thiab cov tseev kom muaj rau kev txiav thiab purity ntawm raw cov ntaub ntawv tsawg zuj zus. Tawm tsam cov teeb meem qaum kev nce nqi rau cov khoom siv rov ua dua tshiab, kev paub txog kev txiav cov khoom qub hauv tsev tuaj yeem nqa cov nyiaj tau los tiag tiag.
Ua ntej koj muab pov tseg cov khoom siv hauv tsev qub, koj tuaj yeem tau txais txiaj ntsig los ntawm lawv hauv kev paub zoo ntawm lo lus. Cov khoom siv hluav taws xob feem ntau muaj cov hlau tsis haum, uas tuaj yeem tau txais txiaj ntsig heev rov qab rau cov ntawv tshwj xeeb. Yog lawm, koj yuav tsis tuaj yeem khwv tau nyiaj ntau los ntawm kev rhuav tshem koj tus kheej cov cuab yeej tawg, tab sis yog tias koj tau txais kev lag luam tiag tiag thiab khaws cov ntawv hlau los ntawm cov txheeb ze, cov phooj ywg thiab cov khib nyiab, ces koj tuaj yeem rov tau txais cov nyiaj hauv tsev neeg.
Cov khoom tseem ceeb ntawm tooj liab
Ib qho tseem kim tshaj plaws thiab cov khoom siv hlau hauv cov khoom siv hluav taws xob yog tooj liab. Nws yog cov hlau no uas ua rau cov neeg nyiam saib khoom seem ntau dua li lwm tus, vim nws cov nqi siab thiab dav siv vim nws lub zog.
Piv txwv li, lub raj qub TV tuaj yeem ntim tooj liab nrog qhov hnyav nrog txog 1.5 kg. Qhov xwm txheej phem dua nrog cov qauv tshiab ntawm TVs semiconductor, txawm li cas los xij, lawv tseem tuaj yeem khaws cov tooj liab li 0.5 kg. Cov tub yees txias thiab lub tshuab hluav taws xob tseem muaj cov ntsiab lus zoo ntawm tooj liab windings thiab cov khoom seem, cov ntsiab lus tooj liab ntawm cov uas ncav cuag 1 kg. Tab sis feem ntau cov tooj liab qhov chaw hauv lawv yog sab hauv ib qho txhuas lossis txawm tias qhov cuam tshuam-cam hlau, uas cuam tshuam rau kev siv "grinder" thiab zoo heev ua rau kev cuam tshuam ntawm kev rho tawm ntawm tooj liab seem.
Koj tuaj yeem tau txais tooj liab rau kev ua haujlwm thiab hauv cov khoom siv xws li: hloov pauv, pib, pib txuas, pib sib nqus, teeb roj fluorescent. Kev tsim tawm ntawm cov hlau ntshiab hauv cov ntu no tsis yog siab heev, tab sis vim yog lawv txoj kev siv thiab siv ntau, lawv yog qhov zoo nkauj los ntawm cov ntawv tsis yog siv roj.
Yuav Ua Li Cas Sau Nyiaj Tooj Liab?
Txhawm rau ua kom zoo dua rau kev sau cov khoom seem, nws yog qhov tsim nyog los tsim cov txheej txheem rau kev sau cov khoom siv tooj liab, lawv cov khoom xa mus rau qhov chaw ntawm txoj kev xav, faib rau nws tus kheej thiab, tau kawg, xa mus rau qhov chaw khaws khoom. Cov hauv paus tseem ceeb ntawm cov tooj liab seem suav nrog thaj av pov tseg, chaw tsim vaj tsev thiab cov chaw txawb chaw cia khoom. Chaw nres tsheb tuaj yeem ua qhov chaw nres tsheb thiab cia khoom. Koj tuaj yeem, yog qhov tseeb, nqa tawm qhov kev txheeb xyuas ncaj qha rau ntawm qhov chaw, tab sis rau qhov no koj yuav tsum tau tas li muaj tag nrho cov cuab yeej tsim nyog nrog koj, yog li qhov kev xaiv no tsuas haum yog tias koj muaj lub tsheb.
Txais tooj liab kom tawg tau yog ib nrab ntawm kev sib ntaus sib tua. Qhov tseem ceeb tshaj plaws yog kom muaj txiaj ntsig rau muag cov mined hlau. Thaum lub xyoo, cov nqi rau cov khoom tsis muaj qhov quav yuav hloov tau zoo heev, thiab txij li lub caij ntuj sov yog lub caij tseem ceeb rau kev ua haujlwm tooj liab, nws yog qhov tsis tsim nyog xa nws thaum lub sijhawm no. Nws yog qhov zoo dua khaws cov tooj liab mined kom txog thaum lub caij ntuj no thiab tos rau qhov nce ntawm tus nqi ntawm kev lees txais, yog li nws zoo dua yog muab tes tooj liab rau cov ntawv sau rau hlau.
