prereduction

1.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.

采用氢生-原子荧光光谱法,用L-半胱氨酸预还原法,对涂料中砷和锑进行了析。

2.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，还绍了高含碳球团的优点，认为高含碳球团有一定的应用前景。
