Raws li cov khoom siv tsis tau ntawm kev lag luam, kev tshawb fawb ntawm cov khoom lag luam tsim khoom ntawm cov txheej txheem thiab niaj hnub no, cia txoj kev sib sib zog nqus ntawm cov txheej txheem ntawm tshuab ziab khaub ncaws {}}
Ua ntej tshaj plaws, kev xaiv ntawm cov ntaub ntawv raw yog qhov tseem ceeb {}} zoo tshuaj ntsuam xyuas yog qhov yuav tsum tau ua kom muaj cov khoom siv raw ua kom tiav cov khoom siv {}}
Tom ntej no yog kev tsim khoom ntawm cov tshuab ua kom huv si ntawm lub tshuab ua kom zoo nkauj thiab cov khoom siv nruj ua kom ntseeg tau tias lawv qhov chaw ruaj khov thiab ruaj khov nyob rau hauv qhov kub thiab kub siab chaw .
Tom qab ntawd los rau lub rooj sib txoos ntawm lub tshuab ziab khaub ncaws .} Thaum lub rooj sib tham tau ua tiav, nws yuav tsum tau ua raws li kev sib dhos, nws kuj yuav tsum tau kuaj xyuas cov khoom sib dhos, kev nyab xeeb thiab kev nyab xeeb ntawm cov khoom.
Tom qab kev sib tw ua ke tiav lawm, lub tshuab ziab khaub ncaws yuav nkag mus rau cov duab thiab cov khoom lag luam tsis zoo, tab sis tseem ceeb tshaj, nws yog los tiv thaiv corrosion, tab sis tseem ceeb tshaj, nws yog los tiv thaiv corrosion, yog los tiv thaiv kev zoo nkauj, tab sis tseem ceeb tshaj, nws yog los tiv thaiv corrosion, yog los tiv thaiv corrosion thiab zoo nkauj} Cov cuab yeej siv hluav taws xob}
Thaum kawg, txhua lub tshuab nqus kom muaj kev soj ntsuam zoo ua ntej tawm ntawm cov hoobkas {}} Kev kuaj mob, kev tshuaj xyuas kev nyab xeeb, txhua lub cuab yeej tuaj yeem ntsib tus neeg yuav khoom {}}
Cov txheej txheem ntau lawm ntawm lub tshuab ziab khaub ncaws yog qhov ua kom zoo dua qub ntawm cov tshuab raj thiab kev sib tw ua kom zoo dua qub, nws ntseeg tau tias cov kev ua kom zoo nkauj ntxiv rau kev txhim kho ntawm txhua txoj kev ntawm lub neej.
