prereduction

The content of As and Sb in paints are analyzed by hydride generat io n atomic fluorescence spectrometry (HG-AFS) and L-cysteine prereduction proces s.

采用氢化物发生-原子荧光光谱法,用L-半预还原法,对涂料中砷和锑进行了分析。

The results show that the coal, oxygen and energy consumptions of fast prereduction at high temperature and final reduction in iron bath are less than those of COREX process.

另外，还绍了高含碳球团优点，认为高含碳球团有一用前景。
