    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 Ntsuas Hydrostatic

    Txhua qhov ntev ntawm cov yeeb nkab yuav tsum tau kuaj los ntawm tus neeg tsim khoom kom muaj lub zog hydrostatic uas yuav tsim cov kev ntxhov siab hauv phab ntsa yeeb nkab tsis pub tsawg dua 60% ntawm qhov tsawg kawg nkaus ntawm qhov kub thiab txias. Lub zog yuav tsum txiav txim siab los ntawm cov qauv hauv qab no:
