a. Iyo Deoxidation nzira inosarudzwa seinotevera:

FF: Simbi yakaurayiwa zvizere ine nitrogen inosunga zvinhu mune huwandu hwakaringana kusunga inowanikwa nitrogen inowanikwa (semuenzaniso min. 0,020% yakazara al kana 0,015% solux al).

b. Iko kukosha kwakanyanya kwe nitrogen hakuratidze kana mimwe yemakemikari ichiratidza mashoma ehuwandu hwehuwandu hwe0,020% neine shoma al / n chiyero che2: 1, kana zvakakwanira zvimwe zvisungo zve-n-zvinosunga zviripo. Iyo n-inosunga zvinhu ichanyorwa mugwaro rekuongorora.
