a. Txoj kev deoxidation yog raws li nram no:
FF: Cov hlau uas tua tag nrho uas muaj cov khoom sib txuas nrog nitrogen txaus kom sib txuas nrog nitrogen tau (piv txwv li tsawg kawg 0,020% tag nrho Al lossis 0,015% soluble Al).
b. Tus nqi siab tshaj plaws rau nitrogen tsis siv yog tias cov tshuaj lom neeg qhia tias muaj tsawg kawg nkaus Al tag nrho cov ntsiab lus ntawm 0,020% nrog qhov tsawg kawg nkaus Al/N piv ntawm 2:1, lossis yog tias muaj lwm cov ntsiab lus N-binding txaus. Cov ntsiab lus N-binding yuav tsum tau sau tseg rau hauv Daim Ntawv Tshuaj Xyuas.

Kev piav qhia txog khoom

Peb cov kav dej tiv thaiv hluav taws yog ua los ntawm kev siv cov txheej txheem ua tib zoo uas txuas ntxiv khoov cov hlau zoo mus rau hauv cov duab kauv thiab tom qab ntawd vuam cov kab sib txuas kauv kom raug. Cov txheej txheem tsim khoom tshiab no tsim cov kav dej ntev, txuas ntxiv uas tsis yog tsuas yog muaj zog thiab ruaj khov xwb, tab sis kuj txhim khu kev qha rau ntau yam kev siv. Txawm hais tias koj xav tau thauj cov kua, cov pa roj lossis cov khoom khov, peb cov kav dej tau tsim los kom tiv taus qhov nyuaj ntawm cov chaw ib puag ncig hnyav, ua kom muaj kev nyab xeeb thiab kev ua tau zoo.

Ntxiv rau lawv txoj haujlwm tseem ceeb ntawm kev xa cov kua thiab cov khoom siv, peb cov kav dej sib txuas ua ke kuj zoo tagnrho rau kev siv hauv kev tsim kho thiab kev lag luam. Lawv qhov kev hloov pauv tau ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau cov haujlwm tsim kho, cov txheej txheem kev nyab xeeb hluav taws, thiab lwm yam kev xav tau tseem ceeb.

Thaum nws los txog rau kev nyab xeeb, peb cov kev ntseeg siabkab yeeb nkab hluav tawsyog cov kev daws teeb meem uas ntseeg tau. Peb nkag siab txog qhov tseem ceeb ntawm kev tsim cov txheej txheem txhim khu kev qha, tshwj xeeb tshaj yog nyob rau hauv cov chaw muaj kev pheej hmoo siab. Yog vim li ntawd peb thiaj li muab qhov zoo thiab kev ntseeg siab tso ua ntej hauv txhua yam khoom uas peb tsim tawm.

Qhov Zoo ntawm Khoom

1. Ua ntej, lawv lub zog ua kom lawv tuaj yeem tiv taus cov xwm txheej hnyav, ua rau koj muaj kev thaj yeeb nyab xeeb hauv cov xwm txheej tseem ceeb.

2. Tus qauv tsim kauv ua rau lub yeeb nkab muaj zog dua, ua rau nws ntws tau zoo thiab txo qhov kev pheej hmoo ntawm kev xau. Qhov no tseem ceeb heev rau kev siv hluav taws uas txhua ob tseem ceeb.

3. Peb txoj kev cog lus rau qhov zoo txhais tau tias peb cov kav dej tiv thaiv hluav taws ua tau raws li cov qauv kev lag luam nruj, ua kom ntseeg tau tias ua raws li txoj cai thiab kev ntseeg siab. Los ntawm kev xaiv peb cov khoom, koj tsis yog tsuas yog nqis peev rau kev nyab xeeb xwb, tab sis kuj tseem nyob rau hauv cov kev daws teeb meem uas txhim kho kev ua haujlwm zoo.

Qhov tsis zoo ntawm cov khoom

1. Ib qho tsis zoo yog tus nqi teeb tsa thawj zaug, uas tej zaum yuav siab dua li lwm cov ntaub ntawv.

2. Cov txheej txheem vuam, thaum ua kom ruaj khov, tuaj yeem ua rau muaj qhov tsis zoo yog tias tsis ua kom raug.

3. Kev saib xyuas tsis tu ncua kuj tseem ceeb heev kom tiv thaiv kev xeb thiab ua kom lub neej ntev, uas tuaj yeem ua rau cov nqi khiav lag luam nce ntxiv.

Cov Lus Nug Feem Ntau
