Niaj hnub no, lub sijhawm xa khoom ntev dua thiab tus nqi nce ntxiv tau dhau los ua qhov kev txhawj xeeb loj ntawm peb cov neeg siv khoom.
Nov yog qee yam tseem ceeb:
Txog lub sijhawm xa khoom ntev dua:
Muaj ntau tshaj 2,500 tus neeg mob uas kuaj pom tias muaj COVID-19 thiab yuav luag 20,000 tus neeg mob uas tsis muaj tsos mob hauv Shanghai txhua hnub. Vim muaj kev sib kis COVID-19, chaw nres nkoj Shanghai txawm tias raug kaw rau ob peb hnub. Feem ntau cov thawv yuav tsum tau hloov mus rau lwm qhov chaw nres nkoj, xws li Qingdao, chaw nres nkoj Shenzhen, thiab lwm yam. Qhov no yeej ntxiv qhov deb ntawm kev thauj mus los. Ntxiv mus, qhov ntim khoom thauj ntawm txoj kev loj tau qhia tias muaj kev poob qis zoo li pob tsuas vim yog kev pabcuam kev loj raug ncua thiab kev sib tsoo ntawm cov chaw kuaj mob ntawm ntug kev.
Yog li nws ncua lub sijhawm xa khoom uas dhau qhov kev cia siab thawj zaug.
Txog tus nqi nce ntxiv:
Kev thauj mus rau lwm qhov chaw nres nkoj tsis yog tsuas yog ua rau lub sijhawm xa khoom ntau ntxiv xwb, tab sis kuj ntxiv
tus nqi thauj khoom. Ntawm ib sab tes, cov nqi ua haujlwm thiab lub sijhawm tau nce ntxiv, vim yog qhov thaiv ntawm chaw nres nkoj Shanghai; ntawm qhov tod tes, kev siv txoj kev tswj tsheb khiav ntawm txoj kev, ua rau tus nqi ntawm kev hla tsheb hla xeev nce ntxiv.
Qhov nce nqi kuj yog los ntawm tus nqi khoom siv raw khoom kim dua hauv tsev thiab txawv teb chaws. Piv txwv li, cov khoom siv raw siv rau hauv kev tsim cov teeb, xws li hlau, hlau, zinc thiab lwm yam, tsis txaus vim tias lawv tsis tuaj yeem xa mus rau lub Hoobkas rau kev ua tiav raws li kev tswj hwm kev tsheb khiav nruj heev. Thiab Led chip, driver, aluminium kuj raug siv thaum lub sijhawm tsim cov teeb LED. Vim tias lawv muaj tsawg, nws tsis yog qhov xav tsis thoob uas lawv cov nqi nce siab.
Vim muaj kev tsis sib haum xeeb thoob ntiaj teb ntawm Lavxias thiab Ukraine, cov nqi khoom siv raw hauv kev lag luam txawv teb chaws tau nce siab thaum muaj kev ntshai ntawm kev muab cov khoom siv raw, vim lawv yog cov neeg muab khoom hlau loj tshaj plaws hauv ntiaj teb. Yog li ntawd, cov nqi nce siab, ua rau cov nqi tsim khoom hauv tsev siab dua, uas ua rau muaj kev nce nqi hauv kev lag luam hauv tsev hauv Suav teb.
Zenith Teeb pom kev zoo yog cov chaw tsim khoom ntawm txhua yam LED txoj kev teeb, yog tias koj muaj lus nug lossis project, pls tsis yig tiv tauj peb.
