1, kev sib xyaw ua ke siv kev nkag siab yuam kev
1.1 Yuav cov khoom sib xyaw ntawm tus nqi qis
Vim yog kev sib tw ua lag luam hnyav, chaw sib xyaw rau raw khoom kev tswj hwm nruj. Cov chaw sib tov vam tias yuav yuav cov khoom siv raw ntawm tus nqi qis tshaj, yog li kev sib xyaw ua ke.
Cov chaw sib xyaw ua ke yuav ua kom cov khoom lag luam poob siab, tau ua rau ua rau cov khoom lag luam sib xyaw ua kom qis qis. Thiab qhov chaw sib xyaw dav dav hauv daim ntawv cog lus yuav khoom tsis tshua meej meej cov qauv kev lees txais. Txawm hais tias muaj, nws tsuas yog pom meej raws li GB xav tau, thiab qhov xav tau ntawm gb feem ntau yog tus qauv qis tshaj. Qhov no ua rau cov chaw tsim khoom sib xyaw hauv rooj plaub uas yeej qhov kev twv ntawm tus nqi qis, qhov ua tau zoo ntawm cov khoom sib xyaw tau qis, feem ntau tsis tshua muaj raws li qhov xav tau ntawm NATIONAL tus qauv, nws nyuaj rau ua tau raws li qhov xav tau ntawm lub chaw sib xyaw rau kev siv admixture.
1.2 Txwv cov nyiaj sib xyaw
Kev sib xyaw chaw txiav txim siab txheej txheej ntawm kev sib xyaw ua ke tus nqi saib xyuas yog nruj, thiab txawm tias cov nyiaj ntawm cov cement, cov khoom sib xyaw kuj tseem xav tau meej. Qhov no yuav zam tsis dhau mus rau lub tuam tsev txheej txheem hauv kev sib xyaw ua ke tsim, tsis txhob tawg los ntawm kev txiav txim siab txheej txheej ntawm kev sib xyaw ntawm qhov xav tau ntau tshaj plaws.
1.3 Tsis muaj kev saib xyuas zoo thiab sim ua pov thawj ntawm cov khoom sib xyaw
Tam sim no, rau kev khaws cia ntawm cov khoom sib xyaw, feem ntau cov chaw sib xyaw yog rau cov ntsiab lus ruaj khov, txo cov dej, qhov ntom ntom, ua kom cov dej ntws nrawm thiab lwm yam ntsuas ntsuas ntawm 1 ~ 2 kuaj pom, ob peb qhov chaw sib xyaw rau kev sim ua vaj tsev.
Hauv kev xyaum tsim khoom, peb pom tias txawm hais tias qhov sib xyaw ntawm cov ntsiab lus muaj zog, txo qis dej, ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom tawm thiab lwm yam kev ntsuas ua haujlwm kom ua tau raws li qhov xav tau, kev ntsuas ua haujlwm tseem yuav tsis tuaj yeem ua tiav thawj qhov kev sim, uas yog , cov dej txo tus nqi dej tsis txaus, lossis hloov tsis tau zoo.
