Lub ntsiab tseem ceeb ntawm Lub Cawv Cawv Teeb

Cov teeb roj cawv feem ntau siv rau qhov ntsuas kub hauv qhov qis qis hauv kev sim tshuaj. Tab sis thaum ua kev sim uas yuav tsum muaj qhov kub siab dua xws li" hluav ncaig hluav taws xob txo tooj liab oxide", lub teeb cawv muaj teeb meem ua haujlwm nyuaj. Tsis tas li ntawd, thaum lub cawv teeb tau siv rau cov nplaim hluav taws, cov nplaim daj ntawm lub teeb cawv yuav tseem cuam tshuam rau qhov kev sim tshwm sim. Yuav ua li cas nce qhov kub ntawm cov nplaim taws teeb ntawm lub cawv teeb thiab tshem tawm cov xim daj ntawm cov nplaim teeb ntawm cov cawv teeb ib txwm muaj teeb meem loj hauv tsev kawm nruab nrab kev sim tshuaj qhia." cov nplaim hluav taws tsis muaj roj ntau lub hom phiaj cawv cawv" tsim los ntawm peb kev sib xyaw ua ke rau cov cawv teeb thiab lub tshuab tawg, thiab tuaj yeem tshem tawm" daj" ntawm cov nplaim taws nyob rau hauv ib txwm teeb pom kev zoo, rau cov nplaim hluav taws cov tshuaj tiv thaiv, iav raj ua, thiab cua sov dav dav Thiab qhov kub thiab qhov siab tshaj thiab kub sim ua kom yooj yim.

(1) Raws li qhov khoom siv hluav taws xob cua sov.

(2) Nqa cov nplaim hluav taws tawm.

(3) Kev kuaj cov kab mob me me yog siv rau kom tsis muaj menyuam, thiab lwm yam.

(4) Kev ntsuas ua iav.

(5) Kev tsim cov khoom siv tes ua lwm yam.
